Have you tried using adaware? If this spyware/scumware isn't wide spread they might not have it in their definitions yet, but I have had great luck with them. The URL is:

If anyone doesn't know: adaware is like anti virus software, but for spyware/scumware. They release updated definitions for it to keep you protected from the latest in scumware.
Give it a try, um, or don't.
