Kazaa Cleaner will remove spyware bundled with the kazaa desktop. Personally I prefer kazaa lite, but hey, this would do well if you're like me and have a desktop machine where someone (else) has installed the "real" kazaa desktop and let spyware run free on their system.
Update: As BB notes (where I originally got the link) this may or may not be completely legit, and apparently gives your AV software a fit. I'm not using windows right now, so I neither can vouch for this. Anyone try it yet?
