Spybot – Search & Destroy

Spybot – Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. 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.

Even if you don’t see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there’s no harm giving it a try to see if something has invaded your computer.
