Antivirus XP is a rogue anti-spyware program which is a clone of Antivirus 2008. Both Antivirus XP and Antivirus 2008 are known to come from Zlob.Trojan which is a Trojan infection that is usually downloaded through a fake video codec or malicious website. Antivirus XP may confuse computer users into thinking that Antivirus XP is a program that is related to Windows XP. We know for a fact that Antivirus XP is far from anything related to Windows XP or any of Microsoft’s products. Antivirus XP is an out-right scam and should be taken seriously due to the fact that it can potentially mess up personal data or files. (via)
