Spybot – Search & Destroy detects and removes tens of thousands of spyware and similar malware from PCs. It can also clean usage tracks and fix registry issues. Spybot is freeware for personal use.
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 haven’t 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.
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-Search & Destroy allows you to fix some registry inconsistencies and extended reports.
