You use Kazza?
There are probably better P2P file sharing programs out there. Kazaa apparently has spyware in it, and is even vulnerable to a new worm..
Read about the worm here
You might want to try running Ad Aware on your system to see what sort of spyware crap Kazaa has installed on you. The thought of having software monitor and report my surfing habits is more than a little annoying.
