Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications.
Free for private use. Companies and institutions need to buy licenses for the commercial versions of our software. There are two editions of Spybot S&D for non-private use: Spybot S&D Small Business Edition and Spybot S&D Corporate Edition.
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. If you see new toolbars in your Internet Explorer that you havent intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware.
