AntivirSystemPRO (Antivir System PRO, AntivirSystem PRO, Antivir SystemPRO) is the latest in a series of fake anti-spyware, or rogue anti-spyware, programs. These programs are being distributed through sites hosting Zlob Trojans, which are malware that disguises itself as a video or audio codec that you need to download and install in order to use a particular video or audio file. Once AntivirSystemPRO is downloaded to your computer, it will automatically start and act as if it is scanning your computer. It will then provide a list of exaggerated and fake results including the actual Zlob Trojan that installed it in the first place. It will then prompt you to purchase the full commercial version of the software before you can remove these items. This is a complete scam, and the results are a tactic used to scare you into purchasing their software. It is recommended that AntivirSystemPRO be removed immediately from your computer system.
