text: how can i tell if someone has hacked into my pc,and whom it might be?   goto http://www.symantec.com, get the system works and the firewall. i have a sygate, but sym owns that now too. get behind a "hardware" firewall like netgear as well.. pluggin your excess ports with cobal viruses will keep out sneakers, but my sygate watches them and lets me know who is comming and going and what for. rule of thumb. if you don't recognize the program don't allow it until you look it up.. yea its a pain in the butt but its really the only way to stay half way on top of it. if you download anything ftp, game mods whatever.. scan them before you open them. not fool proof but its better then just bending over and greasing it for them!. my nortons system works (symantic) back traces and so does my sygate..pretty handy. three times it traced all the way back to the persons computer, i got names, phone numbers addresses. i called the guy in germany on the phone, then is ip. the one in guam was a college student. got him in big trouble. the university admin actually contacted me to let me know. and the person in prog.. i just got a hold of the ip and let them know. but to tell you the truth.. since i got behind a hardware firewall.. no problems!. get one (around $120.00) and beef up your security for pete's sake.. microcrap has some killer freebies like malicious software remover and you get a free version of adware from lavasoft.. also.spybot seek and destroy from safer networks.. free free and free..
