How to remove "Antivirus Soft" fake security program? (Uninstall guide)

Don't Copy From This Blog...

Antivirus Soft is a fake anti-virus program that is usually distributed through the use of fake online anti-malware scanners and various other bogus websites. Actually it's a Trojan virus, but it shows up as anti-virus software and even pretends to be a legitimate one. Antivirus Soft is a scareware or badware from the same family as Antivirus Live. Once installed, it simulates a system scan and gives a list of false computer threats or infections just to make you think that your computer is seriously compromised. The scan results are absolutely false, so don't worry. The only real infection is Anti-virus Soft itself. It will constantly ask you to purchase the program in order to remove the infections and to protect yourself.
