Antivirus XP 2009

XP antivirus 2009 is a fake antivirus software that has infected quite a few of our clients. After it is installed, they try to convince you that you have a virus on your system and that if you pay them $50, they can remove it and keep your system protected. It is very easy to remove, and below we will describe how to go about removing it.

The program is only caught occasionally by antivirus scanners. The (bastard) authors change the name of the file, and it seems to slip right past most scanners.

Fortunately, it is very easy to remove using combofix if you have an uninfected computer: Follow the steps below or go to http://www.bleepingcomputer.com/combofix/how-to-use-combofix for additional information.
