Spybot - Search & Destroy is an anti-malware application designed for on-access and on-demand scanning and removal of various kinds of malware, including spyware, adware, hijackers and trojan horses. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies.
Spybot not only provides detection and removal of adware and spyware but also antivirus protection. Spybot v2.2 includes a Professional Edition license valid for 30 days, so you can try and test all the features of the program.
