The malware discovered these days disguises itself as WGA

A virus discovered these days disguises itself as Microsoft Windows authentication software.

Named W32.Cuebot-K, the malware spreads through American Online messaging software. Deceiving the unsuspecting user, he disguises himself as the so-called Windows Genuine Advantage and then takes effect after the first restart.

This will turn off Windows XP's built-in firewall and open a back door so that potentially attackers can infiltrate the infected computer by exploiting the vulnerability. It also downloads and installs additional malware on your computer by connecting to the Internet.

The program tries to forward itself to other users in the form of an empty message under the file name "wgavn.exe". According to software security companies, users of AOL's instant messaging app are not the only ones at risk.
