Programs named ‘XP Antivirus 2009′, ‘XP Virus 2008’, ‘’Vista Antivirus 2009′, or ‘Antivirus XP 2009′ are malicious programs disguised as antispyware utilities that are spreading through the Internet.

‘XP Antivirus 2008′ usually comes up after you install a video codec (especially from a pirate or warez site) and can include trojans, malware and viruses.

‘XP Antivirus 2008, 2009′ normally generates fake and misleading system popup error messages so end users are actually tricked into paying money for it.

These could have names such as zlob.trojan, trojan.vundo and trojan.downloader.
