XP Guardian Removal Guide

XP Guardian is a rogue Anti-Spyware program from the same malicious family of rogues as Antivirus Pro 2010, PC Antispyware 2010 and Home Antivirus 2010. XP Guardian makes its way into the system via a hole created by a Trojan infection. Once active, XP Guardian will deliver a fake system scan result to scare users into believing the system is riddled with malware. These scare tactics are just a ploy to get unwary to spend money on useless software. Do not become a victim of cybercrime and have XP Guardian and all related threats removed from the system immediately.
