Win32 Virus Removal

Windows Test Master is a rogue program that poses as an anti-spyware in order to scare the user into giving away personal and credit card information. Being part of the Fake Microsoft Security Essentials infection, Windows Test Master does this by first displaying fake Microsoft Security Essentials alert messages suggesting that an Unknown Win32/Trojan has been found on your computer.

Windows Test Master will then perform a fake scan at the end of which it will state that one of your files has been infected with Trojan.Horse.Win32.PAV.64.a. The same alert message will then suggest that in order to get rid of this infection you need to download and install Windows Test Master. Pressing ok will start an automated process in which Windows Test Master will infect your computer further and reboot your system.
