Okay, I've got pretty good protection, but I may need another anti spy tool................?

I have McAfee Security with anti virus and anti spyware, and Spyware Terminator. But I know that no one tool will stop all spyware and viruses. I want all the protection I can get for free. What other anti spyware (besides Windows Defender which is garbage) can you recommend personally? I need one that's light on resources and won't slow my computer. Thanks.

Both are free.

Spybot - Search %26 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. 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. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S%26D is free.
