One of my bosses at work swears up and down that her ex is spying on her computer. Supposedly the guy works for a company that is contracted out to install security and monitoring software on school computers and networks and he set up her computer. She doesn't know much. I told her I could reformat her computer and resecure it with some anti-virus and a firewall. My question is, how could I catch the guy in the act if he really was? I kind of doubt it, but her computer sometimes acts on its own and scrolls through stuff, exits windows/apps, and stuff like that. Also, usually when this happens, her internet/phone/cable TV goes out. I think it is all just a coincidence, but anyone have any ideas? How hard is it to access cable modems? I know the cable company can usually connect right in and see what is going on, I would guess it is just some standard/easy procedure. But I'm not sure. Bottomline is I'm just going to reformat anyway for peace of mind.
