It sounds like a trojan or major virus of some kind, shut off or restart the computer, unplug from internet after making sure the latest updates are install for virus, etc. Then do a scan offline and see if it it finds the trojan.

Firstly, I doubt it is a hacker, unless your brother has some interesting information on his computer, more likely it is a newer virus, I would get an upgraded virus registry for my virus detection software, via, your other computer and jump drive it over.

After you have the file on the jump drive, you find your old file and replace it manually. After that run a virus scan, I hope this helps you fix your problem.
change your ip or format your pc or buy a new one
change isp's, use a router, try different operating system like linux, use secure passwords, add several more firewalls, if that fails either reformat computer and add all updates or disconnect computer from the internet ie turn it off.
