What about the rant about a different browser? So far, even with click happy relatives, 4 Windows machines I help maintain are spyware free after migrating them to Firefox ages ago. I actually forgot how long ago I had started this, until I found my mothers laptop was still running Firebird 0.7.

While changing the OS might not be possible, you can at least address the root of the cause in other ways, instead of maintaining 3-5 different spyware detectors.
