Common viruses

The MTX Virus. This is an evil little beast that sends e-mails to everybody in your address book, infects your system files and blocks access to the popular anti-virus web sites. Removing the infection is very difficult and the attachments to the e-mails are often obscene. If you have been infected, then you should call a computer expert to help you clean your system.

The Navidad virus: If your computer gives you a message "could not find winsrvc.exe" when you try to open anything then you have the Navidad virus. Most of the anti-virus vendors have a repair tool for the virus. Note you can still run many of your programs from the MS-DOS command prompt.

The KAK worm: A worm that uses html mail to spread and exploits a bug in Internet Explorer. At 5pm on the 1st of the month it will cause the computer to shut down, but apart from that it is just an irritant. Most virus checkers will pick it up but will not remove it properly. Download the "eyedog" patch from Microsoft.
