The following is a quote from the topic How to remove AntiSpyCheck
, which can be read in the Spyware and Malware Removal Guides and Reading Room
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.
