This is a perfect example of why computers should be shut down at night, and not left on. If these "invasions" are being down while the computer is on-line, there are two things to do. First get a good firewall. Second, don't leave the computer logged on when it is not in use. If someone is sitting down at the computer and "invading" that way, change the password(s). --Sam Smilie
