I use Sygate Personal Edition firewall. I use it becuase it's free. When I was on Game Spy Network, I got scanned 3 times. My firewall has a back trace option which only tells some stuff I don't yet understand. I don't want them just to go scott-free. So, I was wondering that if I get scanned next time if there was a program that automatically locks on to their scanning attempt and just shuts down their computer. Nothing malicious or destructive, I just want something to shut down their computer. Thanks for any help.
