VistaAntivirus Pro 2010 is a fraudulent anti-spyware program which usually spreads via trojan. Once you start your computer it installs automatically. This fake security tool acts like a real one, but it is not so. Even if it states your system is infected, do not believe it.
As a trick this bogus system uses its fake scan results. It shows you numerous warnings and pop-ups claiming you have to buy “full” version of VistaAntivirus Pro 2010 and clean your computer from infections. It is also mentioned, this malware is a clone of XP Internet Security and Win 7 Internet Security 2010 malicious programs. All in all, do not fall for the blatant scam and remove this parasite as soon as possible.
