Ok, I'll answer a couple of your questions:
-It's recomended that you leave your comp at rest for awhile, give it a break. It's never good to overwork something.
-About the spying thing, I don't really know but I don't think so. I mean, I'm sure that they don't want people to get illegal copies off their stuff, but I'm not sure if they'd get as far as to actually resort to spying.
