Ad-Aware - Product shot of Ad-AwareSpyware removal software works in one of two ways. Some spyware is designed to provide real time, ongoing protection by scanning all incoming Internet traffic and blocking any threat that it detects. Ad-Aware, for example, runs in the background as your work, and blocks any suspected spyware from being installed onto your PC. It also scans any files that are downloaded from the Internet for any components that it identifies as spyware, as well as preventing illegitimate program downloads and any attempts to alter your browser settings. Ad-Aware is one of the very first spyware removal tools ever developed. -
Spybot Search & Destroy LogoOther types of spyware removal software are specifically designed to detect and remove any spyware applications that have already been installed onto your computer. Spybot Search and Destroy, for example, scans your system to locate any files or registry entries that it identifies as spyware components, and removes these. This type of detection-and-removal spyware is more user-friendly and popular among users. -
Webroot Spy Sweeper - Product shot of SpySweeperWhen spyware removal software scans your computer for potential threats, it inspects each file, application and registry entry against a database of known spyware. It will then remove any matches that it finds. This database is maintained by the software's developer.
Since new spyware is constantly being developed, every each anti-spyware developer is constantly updating its database to keep current. For the same reason, it is important that you constantly update your spyware removal software. Some, such as Spyware Sweeper, will automatically update themselves each time there are updates available. -

Others, such as Spyware Doctor, first disable and isolate (quarantine) the spyware, which you will then delete manually. One key advantage of a spyware removal program such as Spyware Doctor is that it gives you detailed information on the nature, severity and origin of each threat, educating you on which websites to avoid in the future. -
