How to remove the ContraVirus (Removal Instructions)
What this program does: ContraVirus is a rogue anti-spyware application that is known to be installed on your computer without permission by Trojans. Once installed this software will supposedly scan your computer for malware, and report back what is found. In order to remove anything it finds, though, you must first purchase the full commercial version of the software. The scan results ContraVirus reports are fake and exaggerated and are used as a scare tactic to have you purchase the full version of the software. To make matters worse, the program actually installs two fake files, named c:\WINDOWS\wincom27.dll and c:\WINDOWS\system\ext32inc.dll, on your computer and states that they are malware when in reality they are perfectly harmless. It goes without saying that under no circumstances should you purchase this software, but instead remove it and the malware that installed it immediately.

An image of the Contra Virus program can be found below along with a removal guide.
