I agree about the malware, I often make this analogy. I was in an exam today and people went to turn on their computers to write the test, we have two hours, and Windows decides to do an update. No asking, no options. These aren't power users; these people struggle with basic computing and are trying to get through school. So the administration worked with them so they could actually write the test but come on. You don't have control of your machine with Windows and I find that inappropriate.
