Someone has hacked into every computer I have and stolen files and taken up house-keeping to the degree that sometimes I can't get into my dial-up, because he is in there and my ISP does not let that many users on at once. In one computer, I opened at e-mail with no attachment and in about 5 minutes, my computer crashed. I have hundreds of IP numbers but they are very misleading and I can't get anyone to listen to me. How do I prove that the person I suspect is actually the person who is doing this? I'll take all the help I can get.
