Has My PC Got a Virus ?

What is a virus? The term broadly describes any program that tries to hide a malicious function or spread copies of itself on to as many computers as possible.

Believe it or not most viruses are benign, displaying a message or picture at a specific time. There are some malignant viruses that can cause damage to your files and programs. Most viruses in circulation fall into six key classifications:

1. Worm - a self contained program that can spread functional copies of itself to other computer systems.

2. File Infector - attaches itself to ordinary program files, it usually ends in exe or com.

3. Trojan Horse - Noramlly a non-replicating program, designed to perform malicious damage, such as destroying all word processing documents.

4. Boot Sector Infectors - These attach themselves to the boot sector of a disk, either on your hard drive or on any floppy disk that you insert into your floppy drive.

5. Master Boot Record Infectors - Infect the master boot program preventing it from starting in the usual way, for example constantly restarting.

6. Multi-partite viruses - this can infect both the master boot records, or files and disk boot sectors.

How does your PC pick up a virus? They don't just occur, they are introduced to your PC by an outside party and can be avoided if you take appropriate precautions.

Downloading files from the internet or receiving e-mail can put you at risk of virus infection. Contrary to popular opinion it's not generally possible to contract a virus by simply reading an e-mail message. The damage is done by executing files that are attached to your message without first checking for viruses. This could also occur by importing information from floppy disk files that were created on an infected PC.

How do I know if I have a virus? Generally, some of the symptoms might be a discrepancy in the amount of memory you have, running out of hard drive space unexpectedly, programs running or loading slowly, unidentified files appearing, and unexpected crashes or failure to load. These symptoms could also be due to a number of common technical problems, don't automatically assume that you have a virus the moment anything looks out of the ordinary or slows down.

The best way to ensure protection from viruses is to install a specialised piece of software often referred to as anti-virus software or a virus checker. This continually scans for possible problems and alerts you before they can inflict any damage.

The Best Ways to Protect Your Computer Against Viruses

Computer viruses are deceptively small, and though they seem benign, they can cause immense damage. Viruses can have an effect that ranges everywhere from deleting your hard drive, hijacking your web browser and stealing your personal information. A large percentage of computer viruses travel as email attachments. They are often disguised as a funny picture or some other seemingly safe type of file. However, once the attached file is opened the virus can infect your system.

The other most common way for viruses to spread are in simple executable files (.exe for pc's and.app or.dmg for macs), often disguised as part of other programs and that get installed when you run them. These types of viruses, often known as trojans for the stealthy way they get on your computer are harder to diagnose and solve. It is imperative that you never click on, open or run a file or program unless you are sure the author can be trusted.

There are several things you can do to help protect your computer from viruses and malware. The first step is to understand whether or not your computer is already infected. There are a number of symptoms which are emblematic of virus infection.

* Slow Speed - if your computer is 'taking a long time to think about things' such as loading programs or saving data, then your computer may be infected.
* Lost Drives - If you are unable to access certain drives, like disk drives or partitions, you need to run some malware removal.
* No Response - This can be the result of a virus, although that is not always the case as software incompatibilities or hardware configurations can have the same effect.
* Crashes/Reboots - it stands to reason that if your computer starts shutting down and starting itself back up you have a serious virus on your hands.

You can do a number of things to help protect your computer from virus attacks. Many of these are simple or easy, but they should not be ignored just the same. Always remember to:

* Shut Your Computer Down - If you are sure your computer is off then you never have to worry about what it is doing when you aren't using it.
* Disconnect from the internet - Now that no one uses dialup anymore, connecting to the internet hardly takes any time. Best to leave your computer disconnected whenever you can.
* Untrustworthy Programs/Files - If you didn't download it, ask for it or anticipate opening it, then don't open it. If you aren't sure who sent you a file or why you are being asked to download something delete or abort it.

If you do happen to contact a computer virus, which happens to most of us despite our efforts, you need to consult a malware removal specialist. This can come in the form of anti-virus programs and security suites, or tech support specialists highly trained in virus removal. Anti-virus programs can detect and delete many types of malware that could harm your computer, whereas a removal specialist can help you troubleshoot the viruses that can hide from security software. Don't forget to always keep your firewall up and your anti-virus software constantly updated, especially if you spend a lot of time on the internet.

New fake antivirus accepts SMS payments

There's a new twist with some fake antivirus scareware that has cropped up. It accepts payment via SMS, according to antivirus firm CyberDefender.

Typical rogue security programs infect the system first, then display pop ups warning that the computer is infected, and request payment to clean it up. The new programs are seemingly more genteel, asking for the money before the program is installed and infects the system, said Achal Khetarpal, threat research director at CyberDefender. Of course, a payment does nothing to "fix" a system and means criminals now have your money and possibly your credit card information.

When a potential victim happens upon a Web site hosting the malware, a dialog box pops up that looks very much like an installer window for a legitimate antivirus product, according to screenshots from CyberDefender. It says "Welcome to" and names a popular antivirus software and suggests closing other applications. If the victim falls for the ruse, it then displays a message that says "To complete installation, you must go through activation" and offers several ways to pay, including SMS (Short Message Service), WebMoney, and credit card.

If you click "cancel", the program won't install, compared with typical fake antivirus programs that have already infected the system by the time the victim realizes what is happening and keep displaying the annoying pop-up messages, even after reboot, Khetarpal said.

The company has seen five versions of the rogue security programs masquerading as software from Avast, Norton, McAfee, BitDefender, and RootKitBuster, and they, as usual, target Windows systems.

Khetarpal could not say how widespread the malware is but said he has seen it in a "lot of Web sites" and in relation to search results for popular and trending topics.

Fake AV scammers aren't the only ones to hop on the SMS payment bandwagon. Scammers were found to be seeking payment by SMS for fake browser updates earlier this year, according to GFI Labs.

Kaspersky Lab warns of fake trial resetter app

Kaspersky Lab, a developer of secure content and threat management solutions, is warning users of key generators and software cracks that can steal information from computers.

The malware, identified as Trojan-PSW.MIL.Agent.wx, disguises itself as a Kaspersky Trial Resetter, which is used to reset a software evaluation period that has expired.

Instead of extending the evaluation period of a legitimate software, it steals information from the infected computer -- from passwords saved in a web browser to other installed applications.

Kaspersky Lab said Microsoft's Internet Explorer is the browser most targeted by the virus, followed by Mozilla Firefox, Google Chrome and Opera.

The Trojan has so far stolen information from MSN accounts (400), Ebay accounts (175), Facebook accounts (169) and ICQ accounts (116), the company said.

"I hope these statistics will convince you that downloading pirated software is not a good idea," said Kaspersky Lab security expert Nicolas Brulez.

He added, "Users who thought they were downloading a crack for a security solution ended up being infected. It's also clear that saving your passwords within your browser isn't the best idea."

According to Brunez, a total of 1,109 computers -- or an average of 48 a day -- have been infected in 23 days. The malware was reportedly created on January 31 this year and was detected on February 6.

Germany is said to have the most number of infections at 29%, followed by Holland (11%), France (3%), Poland and United Kingdom (1% each). The remaining 55% are spread out across the globe, Kaspersky Lab said.
