I've seen debates here in the forums about which is better, Ad-aware or Spybot, for removing adware/spyware. Here is a pretty good review of them both at Flexbeta. There's a list of some of the applications that they installed and tested. I was amazed that there are some that I have used, that are supposed to stop some of what they are installing, ie, Panicware. Thanks to Warp2Search for this info.
