It’s been a while, so here’s some more viruses to beware of:

Fizzer- An email-based worm, Fizzer copies itself to System32 and can turn non-executable files into copies of Fizzer with a .exe extension. It also force-closes any active programs with the keywords NAV, SCAN, AVP, TASKM, VIRUS, F-PROT, VSHW, ANTIV, VSS and NMAIN, in order to counteract antivirus software.

FakeSysDef - Distributed as “HDD Defragmenter”, this virus is one of many that claimed to be useful software to scan a users computer for hardware failures. In truth, once active it would generate false error messages and pop up a “Fix Errors” message. Once clicked, it would trick users into giving away their credit card information to purchase an “Advanced Module” to fix the non-existent errors. Some more threatening variants would block access to programs and forcibly restart the infected computer until the user attempts to purchase the “Advanced Module”.

Agent - Agent is a family of malicious programs, installed alongside other malware to serve as a backdoor. The Agent viruses root themselves into system directories and download additional malware on infected computers. Some variants are capable of masking other trojans in Task Manager, to prevent their detection and removal.
