Off Topic - Virus Alert: Virus that can damage security applications.

[Guest guest]

There's a Trojan horse out there that is just itching to get on your computer. This variant of the Bagle worm, called BagleD1-L, damages any security applications and antivirus software you have on your computer and then attempts to connect with several Web sites, reports ZDNet. The good news is that it won't wreak havoc on your PC, and the Web sites to which it tries to connect do not contain malicious code; however, antivirus companies F-Secure and Saphos both believe that could soon change.

"Any Trojan horse which turns off your antivirus or firewall can open you up to further attack, even by very old viruses," Graham Cluley, senior technology consultant for Sophos, said in a statement. "This Trojan horse is aiming to take advantage of people's reflex reaction when they receive an executable file via e-mail. Users who want to install software on their computer should be receiving it from their IT department, not from friends at other companies or potentially dangerous spam mailings."

This Trojan is somewhat different in that it does not self-propagate by stealing the infected PC's address book, but it has been highlighted by several security companies because a high number of e-mails containing it have been detected, reports ZDNet. The executable files are named "doc_01.exe" or "prs_03.exe"; both are contained in a ZIP-file attachment that must be opened. The files have to be run manually before the computer is infected.
