Spybot Search and Destroy
I personally like this anti-spyware, aside from being free the maker of the software is updating it o regular basis. This software works on Windows XP, Vista and Windows 7.
Spybot-S&D can also clean usage tracks, an interesting function if you share your computer with other users and don’t want them to see what you have been working on. And for professional users, Spybot-S&D allows you to fix some registry inconsistencies and extended reports.

Ad-Aware Free Anti-Malware 8.1.3
One of the first applications built to find and remove malware and spyware, Ad-Aware’s reputation is well-justified. The latest version continues the publisher’s tradition of adroitly addressing user concerns, but isn’t yet perfect.
Building on the improvements made in version 8, former Ad-Aware users should be glad to hear that the program installs faster than it used to. Without a doubt, though, this version of Ad-Aware improves greatly on what has come before. It loads faster during your boot cycle, and scans are faster. Empirical tests noted that while the Quick Scan finished in less than 10 minutes for version 8, the current version’s Quick Scan finished in under three minutes.
