Spybot – Search and Destroy is a program that detects and removes spyware including adware, dialers, keyloggers, trojans, and usage trackers. It is updated quite often to keep up with the ever growing number of spyware programs. One of my favorite features is “Immunize”. It immunizes your computer against some 94,000 threats like blocking bad websites and downloads before they can cause harm to your computer. Spybot also gives detailed descriptions of the threats it finds. This is very helpful.

Spybot – Search and Destroy works on Windows. It is free, but the author accepts donations.
