>>Same here. I was using Ad Aware too, but it wasn't finding/removing some things completely (like Alexa), and it also had a regular "false-positive" occur for one good app. I got Spy Sweeper about a month ago, and it's doing a much better job.

>I talked a little bit too fast. An hour after it was running, I got the blue search bar again on top. I run it again and it just can't remove that anymore.

I didn't mention that I also DLed and ran a complete scan of McAfee Anti-spyware, in addition to Spy Sweeper, to get my Dell/XP clean. Between them, they got everything - but as Fred said, I think it required at least one boot-scan, maybe 2.
