AntiSpyCheck is the latest rogue anti-spyware advertised
and installed through the Zlob Trojan. The Zlob Trojan is a malware that masquerades
as a video or audio codec required to be installed in order to watch a movie
on the Internet. In reality, though, when this Trojan is installed, it will
install a variety of malware that displays advertisements and fake alerts stating
that you are infected with various security risks. It will also advertise, and
install, the AntiSpyCheck program on your computer without permission.
Once installed, AntiSpyCheck will automatically start scanning your computer
and list various security risks that are supposedly present. In order to remove
any of these risks, though, you must first purchase the program. These supposed
infections are in fact not real. They are instead legitimate programs and directories
being falsely marked as infections in order to scare you into purchasing AntiSpyCheck.

window.
