Spyware - Different Types

Spyware is more dangerous than a virus. It can steal personal data and track your internet habits. It might be concealed in a free screensaver or other software that you download. Computer safety expert Leif Wheeler advises us to be aware of any offer of free software. Many times, spyware is hidden in legitimate software. Be cautious of deals offered by well-known companies. Crooks and thieves often create web sites that resemble Adobe, Google or Microsoft, says Wheeler. They instruct you to download upgrades which secretly contain spyware. Common sense should tell you to download things like screensavers or wallpaper only from a company's registered web site. Have a safety talk with anyone who uses your computer. Run an anti-spyware application. The schemes for stealing are the same, notes Wheeler. What's changed is the technology. The rest of us have to try to stay one step ahead.

There is a type of spyware that the New York Times has labeled as "Stealware" and what spyware researcher Ben Edelman refers to as "Click Fraud", also known as "Affiliate Fraud". The most notable vendors of this kind of spyware are 180 Solutions and WhenU. This spyware redirects the payment of the rightful affiliate's commission to the account of the spyware vendor.

An instance of spyware rarely "exists" alone. An afflicted computer can rapidly become corrupted with a lot of spyware devices. Frequently, users will notice erratic behavior and a decline of the system's operation. Spyware contamination can cause considerable inappropriate CPU activity, network traffic, disk usage and the slowing-down of the legitimate uses of these resources. Stability issues, system crashes and application crashes are also very common. Spyware which disrupts the networking software normally causes problems connecting to the Internet.

A Trojan horse, by definition, sneaks in a danger-some program cloaked as something acceptable. Many spywares get spread in this way. The representative of the spyware presents the program as a suitable utility, for example, as useful software or as a web-accelerator. Users then install the software not suspecting that it could do harm to their computer. A classic case of this is Bonze Buddy, a spyware application designed to trick children, claims that: "He will explore the Internet with you as your very own friend and sidekick! He can talk, walk, joke, browse, search, e-mail, and download like no other friend you've ever had! He even has the ability to compare prices on the products you love and help you save money! Best of all, he's FREE!"

Often times, spyware programs are revealed by visibly presenting advertisements. Some spyware simply displays pop-up ads on a pre-determined schedule. For example, a pop-up may appear when the user opens a new browser window. Yet other types display ads when the user visits a specific type of site. Spyware developers use this as a selling point when pitching their wares to advertisers who want to buy ad placement in pop-ups shown when the user lands on a particular site. It is also one of the reasons why spyware programs collect and store information on user behavior.

Computer Viruses - 4 Easy Ways To Keep Your Computer Free Of Computer Infections

Computer viruses normally infect a computer via email. The following are some suggestions to make your computing safer.

  1. The safest way to avoid a computer virus is not to open an attached email file - if you do not know what it is, who sent it to you, or you were not expecting it (even if it is from somebody that you know.)  This is especially true if the file has any of the following extensions: .pif, .vbs, .scr, .exe, since thsee files are programs that will run on your computer when opened.
     
  2. Don't use the preview pane in Outlook. Some viruses can infect a computer just from the preview pane.
     
  3. When in doubt, contact the sender. Write back to them and ask what is the attachment. If the attachment is valid, they will tell you what it is and what it does.
     
  4. Delete a suspected message, by holding down the SHIFT key and hit DELETE.  This will permanently delete the message.  Just hitting the DELETE key (without the SHIFT key) does not remove the message, but simply moves the message to a deleted folder that can be opened.

However, if you just want to skip all the details and stop messing around with preventing computer viruses, just do what I did; download the a trial of anti virus software from a high quality software vendor, run the program and be done with it.

See the download link below for the automatic PC Tools AntiVirus™ software. I personally use this software to skip all the hazzles with computer viruses.

Remove Nyxem Virus

Nyxem has been programmed to delete Power Point, Word, Excel and Adobe PDF files starting on the 3rd of February and the 3rd of every month thereafter, Besides destroying those types of files, the worm also attempts to disable anti-virus software so that it stops updating and it can also disable the mouse and keyboard of infected PCs. It has also been reported that some Internet users have already lost important files after becoming infected by the Nyxem worm mainly because the clock time on their computer was wrong.

Many antivirus manufacturers have already released patches for Nyxem, but it is estimated that thousands of computers are still infected. Most of these infected PCs are believed to be located in India, Turkey and Peru but many other computer systems worldwide could be hit soon as the Nyxem virus will mail copies of itself to contacts in a user's address book.

To prevent getting infected by the Nyxem worm and the loss of critical data files you should not open attachments or click on Web links within these e-mails, especially if these e-mails have a porn-related subject line. You should also backup any important files that you want to preserve. It is also recommended to scan your computer for viruses.

How Does A Virus Spread

"I love your site and your Tourbus Newsletter! I would like to know how a virus propagates over a network? If you get a virus on one computer - do other users on the network have to do anything to get infected? Is there a good way to protect against this?"

Great question! There are several ways for a virus to spread from one computer to another. Let's look at those, and ways to prevent the propagation of pestiferous programs.

Careful With That Paperclip...

The most common is via an email attachment. I'm not aware of any current exposures in popular email software that allow a virus to spread simply by opening or reading an email.

But plenty of people are still willing to open anything that pops into their inbox. Opening an attachment without verifying its contents with the sender is asking for trouble. Never run a program that you save to disk from an email attachment without anti-virus protection in place. The same goes for Word documents, which can have viruses in embedded macros.

Dubious Downloads

Another common way for a virus or spyware to spread is by piggybacking on other software that you download. If you just can't resist the latest toolbar, file-sharing gizmo, coupon dispenser or email enhancer, you may be at risk. Often these and other downloads come with malware, free of charge. Running a good anti-spyware program will reduce your risk.

Just Click NO!

Ever been to a website and gotten one of those "Click here to install and run {Whatever}" popups? Just click NO! Unless you know for sure that you need to press OK (such as when downloading security updates from Microsoft) then treat these popups as threats to your computer.

Sometimes It's NOT Nice to Share

If you are on a network, and you allow your hard drive to be shared (enabling other network users to read and write your files) then you are WIDE OPEN to the stupidity of the other users on the network. If any one of them got a virus, there's nothing to prevent it from copying itself to your computer via the network share. Unless you absolutely have to share your hard disk, don't. You can check to see if you have enabled sharing by right clicking on the drive icon in My Computer, then select Sharing.

The SneakerNet Menace

And don't forget portable media, such as floppies, CDROMs, and those nifty little flash drives that connect to a USB port. Assume that any file you copy from external media could be infected. Keeping your anti-virus protection enabled and updated should protect you here.

Computer Viruses The Nasty Truth

The term, "virus", in computer technology, refers to a self replicating application that spreads by making copies of itself by inserting into other programs, other executables or documents, and when executed begins to perform harmful actions on the system. All computer viruses are deliberately created, not always malicious and some of them may be benign and simply annoying.

Non-Memory Resident and Memory Resident Viruses:

Non-Memory resident viruses, when they are executed, immediately look for other hosts that can be infected. When they infect these targets, they transfer control to the application program they infected. A non-resident virus has a finder module and a replication module. The finder module, once it finds a new file to infect, calls upon the replication module to infect that file.

Memory-Resident virus stays in the memory and do not look for hosts to infect when they are executed. It stays active in the background after its host program is terminated, and infects files as soon as they are opened or accessed by other programs or the operating system. It does have the replication module like the non-memory resident virus, but without the finder module.

Types of Computer Viruses:

File Viruses: These types of viruses are the most common, and mostly infect open files and program libraries on an operating system. The virus functions by inserting itself into a host file, modifies it in such a way that the virus is executed when the file is opened. They are also known as left viruses. Today, there are known viruses infecting all kinds of executables of standard DOS: batch command files (BAT), loadable drivers (SYS, including special purpose files IO.SYS and MS- DOS.SYS) and binary executables (EXE, COM). There are also viruses targeting executables of other operating systems - Windows 3.x, Windows95/NT, OS/2, Macintosh, Unix, including the VxD drivers of Windows 3.x and Windows95.

Macro viruses: Macros are used in most word processing programs such as Microsoft Office in order to automate or simplify recurring tasks in documents. Macro viruses are those viruses that use the application's own macro programming language to distribute themselves, in which an unwanted sequence of actions is performed automatically when the application is started or something else triggers it. These macro viruses may inflict damage to the document or to other computer software but are relatively harmless, and are often spread as an e-mail virus.

Boot Viruses: These were one of the most common viruses prevalent during the early and mid 1990s, when the use of diskettes was popular. These viruses infect or substitute their own code for either the DOS boot sector or the Master Boot Record (MBR), which controls the boot sequence of the PC. The MBR is executed every time a computer is booted so the virus will also be loaded into memory on every startup and spreads to every disk that the system reads. They are typically very difficult to remove, and most antivirus programs cannot clean the MBR while Windows is running. So, bootable antivirus disks are needed to fix boot sector viruses.

Script viruses: They are a division of file viruses, written in a variety of script languages such as VBS, JavaScript, BAT, PHP, HTML etc. They can form a part of multi-component viruses or infect other scripts such as Windows or Linux command and service files. If the file format, such as HTML, allows the execution of scripts, they can infect it.

Virus Removal Software And Information

I hate viruses, and so does everyone else who has ever gotten them or will get one. Since 2006, 1 billion people have the internet, which means that there are now more viruses then ever.

Viruses come in many forms and with many different problems attached to each kind. Some viruses are designed to mess up your entire computer and destroy all data; others are made just to show you unwanted advertisements every once in awhile. Either way, they shouldn't be on your computer and can be removed by you manually or by virus removal software. First though, let's discuss the most common types of computer viruses and what they can do to you or your computer.

The most known and damaging virus type that exists right now is the worm virus. This type of virus can duplicate itself and it will use the email addresses from your address book, and send itself to those people. This means your friends and family computers could even become infected with this virus.

The next most dangerous type of virus is the Trojan virus, which is a sneaky one, hence the name. Trojan viruses sneak in by disguising itself as a program that provides a legitimate function. But really it is a virus that will damage your computer or steal personal information like passwords. There is also the backdoor Trojan virus, which if your computer was infected with it, someone could take control of your computer through your network or the internet.

Another more common virus is just a plain old fashioned file virus. File viruses can attach to real software, so that whenever you use the software, it will load into your memory and infect other files that are associated with that program. That means that the most important documents and data could be destroyed by one simple click!

The next type of viruses I will discuss is the most common on all computers today, and that is Adware and Spyware. Adware is basically just advertisements that are saved on your computer, and show them selves sometimes in a random pop-up or when you type in a web address that is incorrect. Spyware is actually the worst of the two because spyware can log your every keystroke, record every website you go to, and report your statistics back to an individual or company.

Those are really the main types of viruses that exist and are most common on the internet today. Using that knowledge in conjunction with virus removal software, you will be allowed to make sure every virus is removed and not still lingering around somewhere waiting to come out again.

Before I end this article, I would like to give you some very important tips that everyone should know, taken first hand from my computer experiences over the past 10 years.

The most important tip has to do with a computer crash from a virus. Bad people make bad viruses, and those very bad viruses will do things like deleting all of your data, destroying your operating system and maybe even actually altering you're BIOS. Your BIOS controls a lot of technical details on your computer, like your CPU's exact speed, system temperature and most of your components.

This is what you need to do to ensure you can recover from a virus like that. First off make a clone copy of your hard drives data every week, backup your BIOS once every time you change it or a part on your computer. By doing these steps, which actually take very little time with the right tools, you will be protected against bad viruses that destroy that information. All you have to do is restore the BIOS and fully restore your hard drive from the clone image you have, and your computer will be back to normal.

That is all of my information on viruses, and my biggest tip is, if you really want to protect yourself against viruses you need to get virus protection software.

Remove Blackworm

Blackworm started on the 3rd of February and has been programmed to attack an infected computer on the 3rd of every month thereafter. So far it has been estimated that over 300,000 computers have been infected. It can also disable the keyboard and mouse of infected computers. Some Internet users have already lost important files after becoming infected by the Blackworm mainly because the clock time on their computer was wrong.

Like many Internet worms, Blackworm attempts to spread by mailing itself to contacts in a user's address book. The e-mails containing the worm can have a wide variety of Subject fields and attachment names. The worm also tries to add itself to the auto-start programs in the Windows registy. Once a computer in a network has been infected, Blackworm will try to infect all other systems in the network.

To prevent getting infected by Blackworm you shouldn't open attachments or click on Web links within these e-mails, especially if these e-mails have a porn-related subject line. You should also backup any important files that you would like to preserve. Most antivirus products will detect Blackworm assuming the worm hasn't disabled the antivirus software. It is also recommended to scan your computer for viruses and use a firewall.

How To Protect Yourself From Viruses, Spyware, Adware, And Other Nuisances

Spyware/adware is a new major concern for PC users everywhere. Infecting your computer silently (usually installed with programs that seem harmless), spyware and adware can collect personal information about you, as well as cause pop up ads to come up all of the time, changing your browsers home page, sometimes even completely disabling your computer's usability.

This article will show you how to protect yourself against harmful spyware / adware, as well as how to remove current infections, and how to protect yourself from viruses, hackers and other general "malware".

The first thing you can do, if you're an Internet Explorer user, is consider making a switch to the Mozilla Firefox web browser. Firefox can do everything that Internet Explorer can do, and much, much more. Plus it is almost completely spyware "proof", and is much more stable and secure than Internet Explorer. You can go to getfirefox.com for more information.

Next, you'll want to keep your computer up-to-date. To do so, you'll want to download all available updates from windowsupdate.microsoft.com (if you use Firefox, you will need to fire up IE to do this since Microsoft doesn't like people to use other browsers, so they have "banned" Firefox from accessing Windows updates).

Now that you've got a secure browser and have Windows up to date, it's time to talk about the anti-spyware software. The following is a list of the top three players in the free anti-spyware software game:

Spybot Search & Destroy
Download from: safer-networking.org
If you're only going to download one program, get this. Spybot is known as the king of spyware removal – and is completely free, ran buy a guy who volunteers his free time to keeping Spybot up to date.

Lavasoft's Ad-Aware
Download from: lavasoftusa.com
Ad-Aware is technically a for-profit program, but they have a freeware version of their paid software, which is just as good, in my opinion. It picks up a few things that Spybot misses, so it's good to run both.

Microsoft's Newly Released Anti-Spyware
Downlaod from: microsoft.com
Not a must-have if you have the above two programs, but it actually is a pretty good program, especially considering it's a Microsoft product. Might as well have it around to pick up anything the other two might have missed.

Take all of the programs that you have chosen to use, download, and install them. Then, one at a time, update each program, run them, and remove anything that they found. This should effectively remove any active spyware or adware on your system.

Now that you have spyware removed, you'll need hacker and virus protection. To keep hackers out, you will need to install a solid firewall. You can either use the old built in with Windows XP, or download a third-party one.

To activate Windows XP's built in firewall, follow these easy steps:

Click the Start button, and open up the Control Panel.

Open "Network Connections" (or "Network and Internet Connections", then "Network Connections" if you're using the category view).

If you're using broadband, or another form of connection through a LAN, right click on Local Area Connection (or the appropriate network connection), and select Properties. Click on the advanced tab, and click on Settings. Select "On", and don't select "Don't allow exceptions". Click OK on all windows to close.

If you would like to download a third-party firewall, Kerio Technologies has a great personal firewall that you can use. It can be found at kerio.com/kpf_home.html.

Grisoft offers a great freeware antivirus program called AVG Free. It is a great alternative to the common commercial antivirus software designed to milk you for more cash with their "update subscription" fees. Updates to AVG are 100% free, forever. AVG can be downloaded from grisoft.com.

To keep your system completely secure, be sure to scan for viruses, spyware and check for Windows updates every week or so. By taking these simple steps, your computer is now many times more secure and less likely to leak out personal information or get a malware infection.

Virus Scanning Or Virus Avoidance

I have had to fix hundreds of computers over the past several years and most of them could have been easily avoided by using antivirus software and making sure everything was up to date. This is not hard to do you just need to learn to make it a part of your routine.

Best Antivirus Software

Viruses are little executable programs that run on your computer, normally without you knowing and can cause an immense amount of damage to so little that you don't even notice. The best way to guard yourself is to not go on the internet, or even better don't own a computer. If that isn't a viable option for you then you are going to need a virus scanner. Most people are going to suggest Norton or McAfee but I have found these to be lacking. I have found in many instances that AVG virus scanner actually will detect more viruses than Norton will. AVG is completely free and can be found by searching through Google. Make sure you update your virus definitions on a regular basis, a minimum of once a week, I suggest every morning. This will ensure that you have the latest up to date virus list so that you are protected and also if you have one of those viruses you can clean and remove it.

Email a Virus Without Even Knowing

Next watch out for email attachments. If you do not know the person who sent the email, don't open it. Most new viruses spread by extracting your email address from other computers and sending you an email with the virus as an attachment.

Downloads From Sites

Some web sites request that you download an ActiveX DLL or Java Applet or some other piece of software in order to use a certain function on their web site. You need to be careful when deciding whether to download it or not. There are a few rules I follow to make sure that I don't download something I should. If you are on an adult site do not download anything unless you absolutely have to. Make sure that the site/company has a good reputation; this can normally be done by searching Google.

Downloading From P2P

If you are downloading from a peer-to-peer program like Kazaa, Bearshare, WinMX or any other P2P program you are at your own risk. Most computers that I've seen that have this software on it end up having plenty of viruses and spyware. Now, this is not due to the P2P software itself but is due to the files that you are downloading through it. If you must have a P2P program, please make sure that your virus definitions are up to date at all times.

Don't Rely On Automatic Update

On of the worse things you can do is to rely on the automatic update that come with the antivirus that you have. This will normally not send you an update notification until a few days after there is an update that you can get. Any antivirus software that I've seen allows you to manually download any updates that are available.

When Should I Scan My Computer

I leave my computer running 24/7 and if you do the same I would suggest scheduling a time somewhere around 2:00am. This allows the scan to run when no one is on it and will catch anything might have gotten by the automatic scan for one reason or another. If you turn your computer off at night, I suggest a scan right when you turn it on for the first time that day.

Conclusion

You will probably still get a virus from time to time but it should be a lot less frequent and will normally be something minor that you will get. Also if you need up getting a virus it will normally be caught within 24 hours which will reduce the amount of destruction that it can cause your computer and to others.

I am an all around big Geek with too much time on my hands. My main services are web design/development and PC repair. I've been doing both of these for the past 5 years and consider myself pretty good at what I do but, more importnantly, I love it. Webcyte Design

The Top Twelve Threats No Computer User Should Ignore

The internet is undoubtedly a fantastic resource for families and offers a rich vein of educational content.

However, there are potential dangers - welcome to the seedy world of viruses, spam, trojans, pornography, spyware and other nasties.

These are the Top Twelve Threats No Computer User Should Ignore.

1. Viruses - A computer program that copies itself. They often disrupt your computer system or damage your data. Viruses are usually received by email attachments so be careful opening anything from a dubious source. They can affect anyone, for example, the destructive Mydoom worm affected one out of three small and mid-sized businesses.

2. Spyware - Sends information about you and your computer to somebody else. Spyware may send the addresses of sites you have visited or worse still, transmit personal information. With today's concerns about identify theft this is a real worry. For example, CoolWebSearch may hijack web searches, home page, and other Internet Explorer settings. Spyware is normally received as part of shareware or freeware downloaded from the web.

3. IP Spoofing - A technique to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an address indicating that the message is coming from a trusted host.

4. Trojans - An apparently legitimate computer program that is really intended to disrupt and damage computer activity by sending information, perhaps even passwords onto a third party without you knowing. As an example, recent emails entitled "Osama Bin Laden Captured" attempted to download the "Trj/Small.B." Trojan if the embedded URL was clicked. This trojan attempts to hijack the PC.

5. Spam - Unsolicited mail often promoting products of a dubious financial or sexual nature. Don't leave your email address on websites and internet bulletin boards as they are harvested by spammers.

6. Adware - puts advertisements on your screen. These take many forms including popups, popunders and advertisements that appear later, even if your browser is closed. Some are sent using the Windows Messenger service which allows a spammer to direct an advertisement straight to your computer by sequentially sending messages to IP addresses. Always irritating, they are also often of a pornographic nature.

7. Diallers - for those of us still with dial up modems, dialler programs redirect calls to a very expensive number. You won't know until you get the bill.

8. Hijackers - Hijackers take control of your web browser and may reset your home page, search bar and search pages. They can redirect you to undesirable sites or stop you going to particular sites.

9. Hackers - With so much personal data available online to anyone with a password you must be sure your password is secure. If you are using your mother's maiden name, your cat's name or your birthday then your password is at risk. Here are two tips for making a secure password. Method One - pick two random unrelated three letter words and two digits. Mix them up and what do you have? A secure password such as "red19cat" or "hotpin73". Method Two - pick a short sequence of words such as Now Is The Winter Of Our Discontent Made Glorious' and you have a password of "nitwoodmg". You could even change the I's and O's to digits.

10. Phishing - Emails purporting to come from reliable sources such as Paypal, Ebay or your bank. Often wanting you to verify your account details, they can look very realistic but are generally scams to harvest usernames and passwords. Always open a new browser winder and type the address there, rather than clicking on the link provided.

11. Hoaxes - Chain letters, scams, false alarms. At best they take up time and bandwidth but at worst vulnerable can be victims of fraud. Pass it on!

12. Stranger-danger – For those of us with children - do you know what they actually do when they are online? Are they working on homework tasks, downloading illegal music or pornography? Or are they chatting to strangers in chat rooms? You should consider blocking access to undesirable sites and logging their activity with a surveillance tool. Oh, and don't forget that where children are concerned, computers should always be kept in a family room and never in their bedroom.

Three Step Action Plan

There are three basic, essential steps that should be taken to ensure your PC is kept threat-free.

Firstly , be sensible when opening attachments or following email instructions from apparently reputable sites.

Secondly , make sure you are using the latest service pack of Windows as Microsoft is continually closing loopholes to tighten up security.

Finally, there's a range of low cost tools such as firewalls, antivirus, spam blockers and spyware killers available. Like everything else they vary in quality and you tend to get what you pay for so always do your research first and perhaps try a free trial before getting your credit card out.

Spyware Attacks! Windows Safe Mode Is No Longer Safe

Many of us have run into an annoying and time-consuming error. With your machine running goofey you decide to run a scan for trojans and spyware. Following the scan, which usually takes fourty minutes or longer if you scan the entire system, you are hit with the "access denied" error. Frustrating, for sure, but being the savvy computer user that you are you decide to boot to safe mode to take care of the issue. No spyware can load when booted to safe mode, right?

Wrong.

The newer variants of the CoolWebSearch, HuntBar, and VX2 infections all load even when safe mode is used. There are a few different ways of accomplishing this, the most common being that the spyware registers itself as a critical system process. This ensures that it is loaded regardless of what happens, and makes it much harder to shut down.

If you can't prevent it from loading then how do you kill it? The answer to that is easier than it might seem. If you're running Windows 98 or ME, then the easiest way is to boot to DOS, and use a command-line scanner to search your hard drive. These scans actually tend to run a bit faster, since they have more system resources available to them courtesy of no GUI being loaded.

"Well, that's all fine and dandy", you're likely thinking to yourself, "I run Windows XP. You can't read it from DOS." True. You can't read NTFS hard disks from DOS. However, you can use Barts PE.

Barts PE is effectively a stripped version of Windows XP. It boots completely from a CD, and loads a simple graphical user interface. Coupled with plugins, McAfee, for example, you can scan your entire computer without the fear that your nifty little infection has somehow loaded.

Virus Spreaders

Sometimes I wonder just what the world's coming to...

For some among y'all out there who read this column each week, you might've noticed a little while back that it didn't run for a week or so. As a result, I've had some people write and/or call and ask me just what was going on? Some thought I had decided to stop writing the column, some speculated that I had signed some kind of deal with "a big city newspaper" which meant that I couldn't write for my current ones anymore, and one person asked if I'd just "had enough?" For the record, the answer to each of those questions is a definitive "no."

I have a great time writing this column each week. It allows me to write about almost anything that pops into my mind, and I love having that kind of freedom. As a result, I seldom have a clue each week as to what I'm going to write about until I sit down in my chair and get to work. So, with that having been said, let me get right into the reason that "Free Wheelin'" went missing for a week or so. It vanished for a while due to the fact that some sweetheart out there in internet land sent me a virus.

That's right, a computer virus. One of those malicious little programs that's designed to wreak havoc on your computer. Viruses cost businesses and individuals tons of money each year, and for what? It makes no sense at all unless I give some thought as to just what type person sends out these viruses. It must be some super sloppy, maladjusted eighteen year old haint times three computer whiz whose closest contact with a woman comes through the serving line at his school's cafeteria, or some super-nerdy, pocket protector wearing geek who's mad at world because he doesn't yet possess a working personality. And, because these people would rather be anti-social than take a good, long look in the mirror we all have to pay for it. No one ever said that life would be fair, huh?

Fortunately, I'm pleased to report that I got out of my situation without too much damage. I did have to pay someone to reformat my hard drive, but I kept back-up copies of most of my stuff so I really didn't get hurt too badly. I also went out and bought some better anti-virus software, which hopefully will screen most of these cyber pests in the future. In the end, though, almost anyone can get nailed with a computer virus, and I've been far luckier than most - the people that fixed my computer told me that a lady brought in one a week earlier that had over two thousand viruses on it! It's a wonder that the "On" switch on her computer even worked with all that mischief lurking around on her hard drive.

In the end, I guess there are just some people out there who are sort of like walking cases of jock itch, they contribute nothing to the world and try and tear down those of us that do. People like the woman who walked up to my son recently at his job as a cashier at a well-known supermarket chain and presented him with over six hundred dollars worth of live lobsters and steaks. And what did she attempt to pay for all that food with? Food stamps. I kid you not, food stamps. Fortunately, the two food stamp cards she presented for payment had both expired, but, even with that happening, she proceeded to put down a dollar and some change in the hope that Will would be stupid enough to accept that for full payment. He politely told the lady that she was about six hundred some odd dollars short, to which she replied, "Well, I'll go someplace else and check my luck there."

So, for all you deadbeats, virus spreaders, bad check writers, child support non-payers, and the like, if I had my way I'd put you all in jail cells with Perry Como music playing in the background twenty four hours a day, serve you Spam sandwiches for breakfast, lunch, and dinner, and then assign guards to sit outside your cells who've just eaten large Mexican dinners. And that's just for starters - don't even ask me what y'alls daily recreational program would consist of. The way I see it, every dog has his day, and it's more than time for some of you bottom feeders out there to stop having yours...

Fighting Or Financing Malicious Software

Come on. Be realistic. How should I approach security for my computer in the same way as I would approach security for my car or home? The answer is simple, just apply the same principles, not the same mechanisms. Why do I want to protect my car and my home? It prevents people from invading my privacy. What else is it when someone breaks into your car? A thief has no respect for the private assets of someone else, he takes what he wants, and an arsonist has no respect for the private assets of someone, he burns what he wants. Squatters have no respect for any private property, they occupy whatever piece of land they want. That is why we have alarms, security systems and security guards to protect our assets and most important of all our privacy. We don't like strangers strolling round on our premises, we take the necessary precautions to keep them off our property by putting fences and walls around our houses.

Your computer is nothing other than your private electronic property. Why would you go to all the trouble to keep unwanted people away from your home if you don't mind it when unwanted software crawls through your PC? You make online purchases, do online banking transactions, log into your e-mail, enter several passwords to keep people from gaining unauthorised access your private and critical information. Sure, so why would you want a key-logger or password-grabber to infiltrate your computer and steal all your important and private information? You need an anti-virus program, a spyware and ad-ware scanner and some kind of resident shield to prevent all these malicious programs from accessing your PC. We are talking about millions of home users who don't have the kind of budget to afford all these programs. That is why so many people ignore the threats of malicious software because it is just too expensive and not that important, to them, to battle them. It helps nothing to educate users against these threats if you can't empower them.

Many of the big anti-virus companies refuse to distribute free-ware versions of their software to help home users battle these threats. After all, it is home users that are the easiest targets for infections and they are the pawns for Denial Of Service attacks. This is where smaller anti-virus and -spyware companies made the difference when they introduced free, fully functional programs for home users. They even maintain these versions by updating them as new threats make an appearance. It clearly indicates that their main goal is to fight malicious software and not only profit. Companies like these make a positive contribution to the online community by empowering home users to battle the villains of the online world.

Home users no longer have an excuse for not protecting their computers. Not only companies, but also individuals have developed some useful tools to help their fellow man. The biggest problem users may face now is to make the right choice between all the free security software available today. That is why informed members of the online community have to share their knowledge with the uninformed to help them make the right choices and stay clear of fraudulent and malicious software.

Viruses, Trojans, And Spyware - Oh My!

Have you ever had to call Symantec or McAfee to ask them how to remove a virus? Or have you spent hours online trying to figure out how to remove spyware, only to find out that you did something wrong and now your computer won't boot? I know your pain and frustration with just trying to use your computer without worry. As a computer technician at ARCH Computing Services, I know how hard it can be to pay someone to remove viruses and spyware. In fact that's how I started in the computer business. I didn't want to pay someone to fix the problems that I usually caused. A little voice in my head told me "I can build a computer, it doesn't look that hard!"

Six years later, and a lot of dead computers in the beginning, have placed me where I am now. Let me tell you, it's a full time job, even when I'm not at work. There is always some new technology being developed, and of course security is a never-ending battle with new viruses, trojans and spyware daily.

The internet is full of how-to information. You can learn everything from how to make the perfect loaf of bread, tune your car, or remove a virus. Making a loaf of bread seems to be easy, and it probably is. Even if you end up making flat bread or burnt bread, you're not out a lot of money or in too much trouble. On the other hand, if you try to tune your car and break a spark plug or put the wires back incorrectly, it could end up costing you a lot more to fix it. All you wanted to do was save a few bucks and do it yourself. I've burnt bread and I've tried to fix my own car. The bread was thrown in the trash, the car I ended up taking to an auto mechanic and having it fixed right, which of course cost me much more than money, it cost me time.

You must be wondering what my point is. Yes, removing a virus or building a computer isn't really that hard of a task…if you live and breathe computers like I do and others do (we affectionately call ourselves Geeks). Let's take a look at the following scenario.

James is a real estate broker, and a damn good one. He makes his living helping people find the best buy for their dollar. As a result James keeps an extensive client list on his computer. Somewhere along the line he manages to pick up a nasty Trojan. His anti-virus software caught it but was unable to clean it. He does some research online and finds a site that explains how to remove the Trojan. After following the instructions he reboots his PC only to find that his machine will not boot. In frustration he goes to another computer and looks up information on boot problems and finds out that the best thing he can do is reformat his hard drive and re-install his operating system from his backup. Oh, by the way, he hasn't done a backup in over 6 months. By this time he has spent 4 or 5 hours trying to fix the problem, and now has the daunting task of re-installing his operating system without any backup…

The moral of the story here is that he literally wasted hours that he could have spent making a sale or helping a client purchase a house or land. Is the above scenario a little extreme? In some ways it is, but it doesn't fall too far from the truth. Many of the clients I see with virus or spyware problems have tried everything they can to remove the problem, only to find out they spent hours with no results, and often come out worse than they were. By the time they come to see me they are frustrated and just want it fixed. Unfortunately, this does cost them money that they didn't want to spend in the first place, and more importantly in this day and age, it costs them more time. Time is the great equalizer. If James had been able to make a 10% percent commission on a $200,000 house, spending the 65 to 100 dollars to clean his computer wouldn't have seemed very significant.

Nine times out of ten an infected computer does require a re-format and re-install. I don't say this lightly. It is usually much easier to backup and start over than spend hours trying to find every little piece of nastiness that was installed on your computer.

Spyware, Viruses, And Other Online Threats - Is Your PC Properly Protected

AOL and the National Cyber Security Alliance (NCSA) released their second annual Online Safety Study a few months back, and the results weren't pretty. While the latest survey did find that users were getting better at taking the steps necessary to keep their PCs properly secured, the findings show that there are still plenty of people who just don't understand online risks.

Some of the key facts uncovered by the Online Safety Study included:

  • 81% of home PCs lack one of the three main sources of protection - a secure firewall, anti-virus software, and spyware protection.
  • 56% of users had no anti-virus software installed, or had not updated their virus definition files in the last week.
  • 44% of users did not have a properly-configured firewall in place.
  • 38% of users lacked spyware protection.
  • Most telling, perhaps, is the fact that even in light of these findings, 83% of users surveyed still believed that their PCs were safe and properly secured.

The online security threat landscape has certainly changed from the days when viruses were home users' biggest worry, but the survey shows that users are largely not keeping up with the times. Every PC connected to the Internet today should be configured with the following (at an absolute minimum):

  • A personal firewall capable of filtering both inbound and outbound traffic.
  • Updated anti-virus software that offers real-time protection, the ability to scan on-demand, and email message scanning features.
  • Updated anti-spyware software that not only scans for and removes spyware on demand, but also proactively protects against threats in real-time.
  • Windows Automatic Updates turned on (to download and install critical security patches, service packs, and updates automatically), or weekly visits to the Windows Update web site to obtain the latest critical updates.

Thankfully, keeping your PC updated and properly protected against online threats needn't cost you a penny. There are a number of anti-virus, anti-spyware, and personal firewall programs available free for personal use. A simple web search will turn up direct links to some of the more popular options, which I will be discussing in more detail in future articles.

For the time being, however, considering beginning your PC lockdown process by taking a look at my beginner's guide to eradicating spyware, The Best Free Anti-Spyware Programs. A secure PC is a fast PC, so take the time to start locking down your home computer today. Your system will thank you!

Switch From Managing Email Security To Managed Email Security

The days of riding horseback through the wilderness to deliver a message are over. But make no mistake; we're not out of the woods yet. The digital world exposes us all to a virtual wilderness. Email offers simplicity to both the messenger and the malevolent.

Email has grown in vitality, now becoming the most important communication tool in the corporate world. The perpetuation of emerging threats has transformed email from an asset to a liability. Gone are the days when organizations could manually cope with the occasional email-borne nuisance. Email security has become a necessity and organizations must know the best way to ensure the integrity of their email network.

Perhaps an even greater threat to your organization's effectiveness is an over-investment in an under-effective email security solution. Organizations must seek a comprehensive, future-proof solution on a platform that integrates flawlessly with their current infrastructure.

The email security market is not bound by in-house software or hardware solutions. Organizations can push the war against spam, viruses, and other email borne threats outside of their network using a managed service.

What is a managed service?

Unlike software and appliance solutions, a managed email security solution sits entirely outside of your network. With a quick change of your organization's Mail Exchange (MX) records, mail is routed through the managed service, effectively filtering your email and delivering only genuine messages to your network. Such an infrastructure offers a number of benefits over traditional appliance and software security measures.

Benefits

  • Instant Deployment
  • Zero Maintenance
  • Failover / Redundancy
  • Disaster Recovery
  • Scalability
  • Bandwidth Savings
  • Complete Threat Protection
  • Future-Proof
  • Platform Independent
  • Low TCO / Quick ROI

Instant Deployment

Since a managed service introduces no hardware or software into your infrastructures, deployments typically consist of only a simple MX record change. Moreover, managed solutions come pre-configured to maximize effectiveness with minimal user intervention.

Zero Maintenance

Updates to hardware and software are a necessary evil that demands time and money. This is especially true with security technology in order to stay ahead of new threats. But a managed service introduces absolutely no hardware or software into your infrastructure. All updates are performed by the managed service transparently to the end-user.

Failover / Redundancy

Implementing a redundant infrastructure is rarely cost-effective, especially in small to medium businesses. Yet, downtime is never acceptable. Deploying a managed solution is your ticket to enterprise-class reliability, without expending financial resources to integrate a redundant network infrastructure.

Disaster Recovery

Internal network and hardware glitches that compromise the availability of your email are inevitable. During downtime, not only is productivity lost, but also data which can cost your organization countless dollars. With a managed service, your email is queued during downtime. After connectivity is re-established, your email is promptly delivered to you. Organizations which deploy managed email security are able to focus solely on regaining connectivity, without worrying about lost messages during downtime.

Scalability

A managed service allows organizations the flexibility to grow without investing in additional information technology. Organizations with multiple geographic locations must purchase, implement, and maintain a software or hardware solution in each location that has a mail server. However, geographically dispersed organizations can be wholly controlled through a managed service, without any additional investments, installation, or maintenance.

Bandwidth Savings

Quality hardware and software solutions can effectively halt the flow of junk messages into end-users' inboxes. However, these junk messages still reach the perimeter of your network. Bandwidth is required to analyze all messages, and messages that are quarantined must be downloaded and stored. With a managed solution, only genuine messages reach your network. Spam, viruses, fraud, and malicious email messages are stopped before they approach your organization's perimeter.

Complete Threat Protection

There's much more to email security than spam and virus protection. Directory harvesting, mail bombs, phishing, dictionary attacks, and many other threats assault vulnerable organizations each day, causing countless dollars in damage and lost productivity. Most appliances and software solutions are only a piece of the email security puzzle.

More importantly, with a managed service you have professionals maintaining your email's security. Spam, viruses, and other email nuisances are growing more sophisticated, and require more sophisticated technology and know-how to combat them. A managed service supplies organizations with access to comprehensive technology and wisdom.

Future-Proof

Anti-spam technology, like no other, has an uncanny ability to lose effectiveness after a year or two. This is because spam is constantly changing, while your software and hardware is staying the same.

Spam is also growing in volume. A few years ago, you may have been receiving an average of ten spam messages a day. A spam solution with a 90% capture rate would catch all but one. Today, however, many users are receiving tens, even hundreds of junk messages a day. More intelligent software is needed to stop these additional messages, without misclassifying genuine ones.

A managed solution's core competency is to stay ahead of email threats. Thus, organizations are always plugged in to a cutting edge solution.

Platform Independent

Regardless of your organization's preferred OS and Mail Transfer Agent (MTA), a managed service can integrate easily into your infrastructure. Even organizations that utilize several operating systems and MTAs can quickly fit under the umbrella of a managed solution.

Low TCO / Quick ROI

Software and hardware solutions can rope you in with a large, non-refundable, upfront investment, and annual recurring fees. On the other hand, a managed solution is typically subscription-based, which can be cancelled at any time for a pro-rated refund. With a lower upfront outlay and minimal maintenance, organizations can realize a return on their investment in much less time with respect to traditional email security platforms.

Take Control of Your Email Network

Managed email security takes the burden off your budget and overworked IT staff and places it on the spammers. A managed service makes email what it was meant to be - an effective, hassle-free, business communication tool.

Free Computer Security Software - A Leaking Seal!

There is nothing wrong with taking less than adequate measures to prevent a bigger damage to anything you treasure if you have financial or other constraints, as long as this is done temporarily over a short time. Similar reasoning applies when it comes to computer security threats.

Unfortunately some (if not most) computer users tend to forget this. They search on the internet for free computer security software which they dump into their computers and hope for the best. Most of the free software developers consistently forget to inform the downloaders of the inadequacies of their software – and they are many and significant!

A simple search for free anti-spyware programs on any search engine yields significant results. If we exclude genuine beta-software from these results, almost all of these anti-spyware programs operate on the principle – "Get infected first, then call us". In other words these programs are reactive. They scan and destroy spyware as it's found in the user's computer. The real downside of these programs is that they offer no real-time protection. Are you surprised? Maybe you've forgotten that "there's no such thing a free lunch"!

The big computer security software developers spend millions of dollars every year developing products that can quickly detect and destroy new computer security threats like spyware, adware, viruses, hacking techniques, Trojans, worms keyloggers etc

Do you think the developers of free computer security software inject millions of dollars in order to bring users of their software regular software updates? I think not!

Computer security software is such a critical purchase that I think one should actually buy the software before bringing home a new PC!

The most critical software that you should have in you PC is:

  1. Firewall - To protect your PC from hackers and internal malware that maybe trying to "phone home"

  2. Spyware/Adware - To detect the "ETs" that are "phoning home" from your PC, endangering your sensitive information such as passwords, credit card numbers and other sensitive information. These programs also use lots of your critical computer resources. That's why your computer is slow and crashing lately!

  3. Anti-virus Software - These can either completely wipe out your critical data or render it or your computer useless. The most dangerous thing is that you may end up (unaware!) being a source of the virus (e.g. through email or infected website pages).

Here are common-sense measures you can take to protect your PC:

  1. E-mail - Avoid replying to chain letters. Also be very careful of image attachment. Hackers attach malicious JavaScript program on these.

  2. Regularly update your anti-virus definitions by running the update function of your security software.

  3. Before buying a computer security software or package make sure that it offers regular updates to keep up with new viruses, adware, spyware and other computer security threats.

I want to repeat what I said at the beginning of this article: There is nothing wrong in taking temporary security measures as far as your computer security is concerned (i.e. using free software/downloads). What is wrong is forgetting that the measure was supposed to be over a temporary period in the first place.

Blogs As Safe Haven For Cybercriminals

To blog or not to blog? Well, why not? Lots of people like either to write or to read blogs -- sometimes both. The much-quoted survey by the Pew Internet & American Life Project, says 27 percent read blogs. 38 percent of all Internet users at least know what a blog is. The survey was made in November 2004 and estimated that 32 million Americans to be blog readers by the end of 2004. So now there must be much more blog readers and writers.

But there has recently been bad news that spoiled bloggers' mood. The security firm Websense found that blogs are "being used as a safe haven by hackers for storing and distributing malicious code, including identity-stealing keyloggers." Since January, Websense Security Labs has discovered hundreds of blogs set by hackers.

There have been scores of articles on this topic since last week. See, for example, the article by Gregg Keizer "Hackers Use Blogs To Spread Worms, Keyloggers" April 13, 2005 at http://informationweek.com/story/showArticle.jhtml?articleID=160702505

The general idea of all these articles is the same: hackers turn to blogs. Blogs are suitable for them: there are large amounts of free storage space, no identity authentication is required to post, and there is no scan of posted files for viruses, worms, or spyware in most blog hosting services.

Such blogs experts from Websense Security Labs call "toxic". In its press-release "Toxic Blogs Distribute Malcode and Keyloggers" http://ww2.websense.com/global/en/PressRoom/PressReleases/PressReleaseDetail/index.php?Release=050412889 they explained how some malevolent individuals use blogs for their own gain.

In some cases cybercriminals create a blog on a legitimate host site and post viral code or keylogging software at the page. Then they attract traffic to the toxic blog by sending a link through spam or spim (the analog of spam for instant messaging (IM). So a good advice never follow links in spam is worth remembering.

In other cases, a blog can be used only as a storage mechanism which keeps malicious code (for example, updates) for Trojan horses that have already been hidden on the users' computers.

"To read or not to read blogs -- that's a question?" Of course to read them, to write them -- blogs are already a part of our culture. But be careful.

While PC users can do little to stay aside of toxic blogs except not following links in spam and spim messages, leading to these blogs. If a blog is used as a storage for malicious code, users can do nothing at all about it.

It is up for blogging tool operators to add security, such as anti-virus and anti-spyware protection, to blog hosting service. They can also limit the types of files that can be stored. And it is high time they made their service more secure, because literally millions of Americans might be in danger of picking malicious code, such as a virus, worm or Trojan horse, simply by reading a blog.

Alexandra Gamanenko currently works at Raytown Corporation, LLC -- an independent software developing which created a technology capable of disabling the very processes of information capturing -- keylogging, screenshoting, etc. It makes the company's anti-keylogging software a solution against information-stealing programs and modules.

Spyware. History And Description

The first known use of the expression "spyware" occurred on October 17th, 1994 in a post that joked about Microsoft's business model. Spyware later came to allude to snoop equipment such as diminutive cameras. In early 2000, the man who started Zone Labs used the term in a press release for a new product. Since then, the computer-community has used the term in its current definition.

Spyware often comes wrapped-in with shareware or other software, and with music CDs. The user installs a program, for example, a file-trading utility or music program. The installer also installs the spyware. Even though the acceptable software itself may not do harm, the wrapped-in spyware does. Occasionally, spyware authors will pay shareware creators to wrap-in spyware with their software. An example is the Gator spyware distributed by Claria. There are instances when spyware authors will repackage desirable free software with destructive installers that add spyware.

Another way of propagating spyware is by tricking users. A program will manipulate a security feature that is supposed to prevent harmful installations. Internet Explorer is designed to stop websites from starting an unwanted download. Alternately, a user action must normally trigger a download (like clicking on a link). Nevertheless, links can prove misleading. For example, a pop-up may look like a normal Windows dialog box. The box contains wording like "Do you want to improve your Internet experience?" with links that look like real buttons reading No and Yes. It doesn't matter which button the user selects, a malicious download will start, installing the spyware on the user's computer. Newer versions of Internet Explorer offer better security against this tactic.

Many unscrupulous spyware creators infect a computer by going after security weaknesses in the Web browser or in other applications on the targeted computer. When the user arrives at a Web site controlled by the spyware creator, the site includes code that forces the download and installation of spyware or infiltrates the browser. This kind of spyware creator will have broad knowledge of commercial-quality firewall and anti-virus programming. This is commonly known as a "drive-by download". It leaves the user an unfortunate onlooker to the intrusion. Conventional "browser attacks" target security weaknesses in Microsoft Java Runtime and Internet Explorer.

Another problem in the case of some kinds of spyware programs is that they will replace the banner ads on visited web sites. Spyware that acts like a Browser Helper or web proxy can replace a site's own advertisements with advertisements that benefit the spyware author. This can seriously affect the revenue stream of advertising funded web sites.

There have been instances when a worm or virus has delivered a cargo of spyware. For example, some attackers used the W32.Spybot.Worm to set up spyware that caused pornographic ads to pop up on the screens of an infected system. By re-routing traffic to commercial sites that are set up to funnel funds to the spyware creators, they can profit even by such obviously illegal actions.
