What works best for me is Lavasoft's AdAware SE Personal 1.06. It has a VX2 cleaner that takes off those adware/spyware files that were previously unremovable and the smartscan is FAST. You'll have to download the VX2 cleaner separately from the add-ons section and there's an updated version available. I used it today after I downloaded a file loaded with adware/spyware that I couldn't get rid of even with Norton's DoD wipe. It worked! Best of all....IT'S FREE!!!!! Just download the freeware version directly from their site.
