Fake/Rogue Software

There are a large number of fake anti-spyware programs active on the Internet. Typically, widely-distributed Web banner ads falsely warn users that their computers have been infected with malware, enticing them to download the rogue software. Once installed, the software uses human engineering and false positives to manipulate the user into purchasing the software. These programs do not actually remove spyware — or worse, may add more.
The following is a partial list of known rogue software. Often the same software is distributed under several names.
