Spybot: Search & Destroy
Spybot: Search & Destroy has been around for a long time, and quite frankly, is probably one of the best spyware and adware removal programs available on the Internet. Although the developers will gladly accept donations, the program has remained free to download and use over the last decade.
The interface is simple and easy to navigate, allowing users to quickly access the program's features via a navigation bar located to the left. Outside the two main spyware and adware removal tools, the software does a number of other useful tasks, such as block browser hijackers, repair the registry, clean out cookies, and more.
Spybot also provides a cool "immunize" tool, which will block the installation of spyware before it occurs (typically by modifying the hosts file). Want real-time protection? Spybot can do that as well, running two processes in the background: Resident SDHelper for adding a second layer of protection for Internet Explorer, and Resident TeaTimer which prevents unwanted files from installing on the PC.
