your pc is the sickest i have seen for a long long time. no firewall no anti-virus.
i think you should stop downloading from limewire and the torrent sites untill you learn a little more about p2p in addition stop downloading free games, they really aren't free. poker, bingo and stuff like that
get rid of norton and in the meantime get the free avg and the free firewall from zonealarm or comodo.
if you continue without reasonable good protection and large downloads from p2p, you are going to spend most of your time visiting here or other similar sites. and very little time enjoying computing.
this is only advice!
get well soon:wave:
