Hi guys. Ive recently started trying to extend my knowledge on hacking so i can prevent others from doing it to me...but the more i read the more i see that i dont know. Basically, over the past few weeks a friend of mine has been basically cutting off my internet. I have zone alarm running constantly, but he has the ability to make my cable die. ITs kinda sad...we'll be playing counter-strike or something and ill kill him or something stupid like that and he'll get pissed and say "brb...imma packet you" or something. Oh, another thing, i'm on a network so i dont know if the main computer needs to have something on it or what...cuz thats my parents and they dont want me putting stuff on their comp.

thanks for the help
