CW Shredder removes some variants of spyware known as the Coolwebsearch Trojan. The Trojan takes advantage of a flaw in a key component of Windows -- Microsoft's version of the Java Virtual Machine -- to install itself via popups often found on porn and illegal software (a.k.a. "warez") sites. Run CWShredder after installing, and have it look for updates. Then click the "Fix" button, and the program will both scan and fix any problems it finds. If your system does not have this kind of spyware, it will give you the good news.
