I'll have to look at Pestpatrol. As a field engineer, all I see everyday is spyware. My experience is this:
1. If you are only using spybot or ad-aware, you're not clean, you need to use both. Basically saying there is no single tool that finds everything. And I don't care what anyone else says, if you scan with spybot, scan with ad-aware after and I'll bet money you find more junk, even if its only registry entries (and no, I'm not talking about stuff in either program's quarantine)
2. Spysweeper is nice, but I see it fail to load a lot on xp machines for some reason. I frequently see an error about failing to load software lists.
3. Even with all 3 tools, some spywares cannot be removed. I bumped into CWS_NS3 yesterday, did a google search, expecting I would have to edit registry keys in safe mode, nope, found nada.
There is no good enterprise solution, but I'll look at Pestpatrol. Right now we're relying on proxy to just kill web access for problem users.
