Have you scanned for Spyware and viruii in general?And possibly need a few critical updates as well. Could be an old worm attacking if security updates are lagging.

Windows Updates
Good antivirus program
One of the most important things of all...behind a good firewall, in my opinion...I prefer routers because they provide a basic hardware firewall through their NAT.
Make sure your Administrator password is not left blank.
