Virus Trigger, otherwise known as VirusTrigger, VirusTrigger 2.1, is new deceptive anti-spyware application. Virus Trigger was created to invade a user’s privacy and attempt to compromise the Internet community. Virus Trigger tends to issue misleading and exaggerated system scan results. Virus Trigger usually installs itself onto a PC without the user’s permission, via Vundo Trojan, another virus or various phony software. Virus Trigger tends to display fictitious system alerts or phony security alerts, so as to trick the user into purchasing the full version of Virus Trigger, supposedly to ensure the removal of all the potential and reported problems. Not only does Virus Trigger cause the user’s machine to slow down dramatically, it would also put their privacy and data at risk.
