I can tell you've never actually tried to uninstall McAfee.

The one (and forever only!) time I had McAfee on a computer (it was free, bundled with TurboTax) when I went to uninstall it after it expired it took an hour-long discussion with their tech support, and even then I am pretty sure remnants were left. About the only software I ever saw that did a "better" job of embedding itself into all aspects of the computer was Norton. I won't allow that one in my computer either!
