One of my friends from high school worked at an electronics shop repairing computers. So I got all my computer repairs done for free!
Once when he was getting rid of some viruses that had infected my computer, he showed me the security log. It was long, with tons of entries. I don't think I would have the patience to sit and go through something like that.
I suppose it would be a good record to have in a court case for something like computer hacking though. But I sure don't envy the person whose job it is to go through those things!
