The SysInternals tools are awesome. ProcessExplorer's ability to show which processes are linked to which DLLs really helps.

The latest versions of HiJack This also have a process explorer that is helpful. I'm not even sure if the program cleans spyware, but it sure can detect it.

I would suggest installing the MVPS Host File when you are done, and updating it weekly at least. It prevents your computer from even THINKING about talking to malicious websites.

Yes, than Mozilla and SpySweeper (which I still think is plotting to take over the world, but that's another story).

Good luck, you can do it, unless its a rootkit, in which case SysInternal's Root Kit Revealer may help, though I haven't tried.
