I'm having a little problem. I have a motorola cable modem and have two laptops tied into it. one by ethernet and the other by USB. When I setup my AV and Firewall (Kaspersky AV and Anti-hacker) I thought that I was safe but after about 2 hrs. of being online (USB) all of a sudden I got a message that popped up on the taskbar saying a new user was added to my network but I have no network. Then I went into my network places and there was a new connection. Am I being hacked? How can I stop it? Please someone help me...... I have sensitive documents on this laptop and might lose my job if any of this info gets out........HELP!
