The Free Software Catalog

Anti-Spyware

These are the best and most effective free anti-spyware packages available. It is a good idea to have at least one of these packages installed. You don't necessarily need to run the active scanner all of the time, however, you should scan your machine on a regular basis. Perhaps once per month or even once per week depending on the kind of sites you tend to visit.

Be wary of some free anti-spyware programs that are really just fakes. While they may or may not remove spyware from your PC they are often nothing more then adware. All of the ones listed here are safe.
