XP Police Antivirus, XPPoliceAntivirus or XPPolice Antivirus, is a rogue anti-spyware program designed to trick users into believing it’s a legitimate Microsoft product. Needless to say, XP Police Antivirus has no relation whatsoever with Microsoft Corp.

XP Police Antivirus may be installed in the user’s computer system by a Trojan, such as Zlob, through a rogue video codec download or the user may have downloaded it from a rogue website. Once Zlob is installed, the user will receive a large amount of fake notification messages stating that his/her computer is infested with spyware. In order to remove these threats, the user will be redirected to a fraudulent website to further purchase XP Police Antivirus’s full version. XP Police Antivirus is also able to emulate a computer system scan. After XP Police Antivirus’s scanner is launched, the user will receive a list of spyware infections supposedly found in his/her computer system as a result.

XP Police Antivirus may be configured to run on every Windows startup. XP Police Antivirus may also cause computer system’s performance to decrease.
