DP's Security Bits

Windows Virtual Angel is a computer infection from the the Rogue.FakeVimes family of rogue anti-spyware programs. This infection is classified as a rogue because it purposely displays false scan results, hijacks your computer so that you are unable to run your normal applications, and displays fake security warnings to scare you into thinking you are infected. This family of infections is spread via three methods. The first method is through web sites that have been hacked to display malicious code that installs the rogue on to your computer without your knowledge or permissions. The second method uses online advertisements that pretend to be online anti-malware scanners that state that you are infected and then prompt you to download and install Windows Virtual Angel in order to clean it. The final method is through the use of Trojans that pretend to be software required to view an online video.

Once the rogue is installed on your computer it will be configured to start automatically when Windows starts. Once started it will perform a fake scan and then state that there are numerous infections present. If you attempt to use the program to remove these infections, though, it will state that you first need to purchase it before it can do so. This is a scam as the scan results are all fake, and in many cases, the infected files do not even exist on your computer. Therefore, please ignore the scan results and do not purchase the program.
