Sounds familar. I have two friends (both with MBAs) and when it comes to taking care of their computers they are lost. One I installed adware and he couldn't believe what it found. Then Spybot put him into shock. By the time I was done he thought he had a new machine...repeated with my other friend later that day. Amazing, very smart people but fail to understand what it takes to keep their computers going.
We all have our specialties. It amazes me when smart people do things that I would regard as completely asinine. They just don't know any better.
