Read on IP ranges, and what different IP #'s mean different Things. As for Getting someone back, yes it would be nice and would satisfy your vengence temporarly, but how does big $ fines sound? yes it is illegal, and if we tell you how to hack someone than AO gets a bad rep. But bassically do whateveryone else has said, get a firewall, trojan cleaner, and from me, whatch what you download, use commonsense on that type of stuff. if u are suppossed to downoad a song and the extension is .bat instead of .mp3 or if you are supposed to download a program, and its only 832 kb, its mostlikely a trojan.
