AV Security Suite Removal

AV Security Suite is fake anti-spyware program which imitates a legitimate antimalware application and belongs to the notorious Antivirus Live family of rogue malware. It acts in the same manner as its predecessors, Antivirus Soft and Antispyware Soft, by trying to convince users to buy a license for the software. AV Security Suite enters a user’s computer via Trojans that arrive at the user’s system via infected PDF files. Once it has been installed on the user’s system, AV Security Suite starts performing fake system scans at regular intervals, returning results that claim that the user’s system is under serious threat. It also creates a number of harmless files that it later detects as dangerous viruses. AV Security Suite uses a Windows-style GUI and pop-ups generated from the Windows taskbar to convince users that this is the real thing. Then it claims that the currently installed ‘trial’ version is inadequate to remove the previously detected false ‘threats and urges the user the pay for the ‘full’ version of the software. However, the ‘full’ version is no more capable of cleaning a user’s system than the ‘trial’ version; therefore no user should ever purchase the false license to this rogue software.

As soon as you find a copy of this malicious software installed on your computer, you should take steps to delete AV Security Suite. AV Security Suite removal involves the stopping of processes, removal of files and folders and the deletion of registry entries. However, before attempting this you should restart your computer in Safe Mode.
