because it slows down my laptop :I
what do you guys use, that isn't a ridiculously huge file like limewire and doesn't have a high rate of viruses?

A couple friends of mine use MP3 Rocket. Not sure about the rate of viruses, but they say they've never had a problem with it. :)
Edit: There are plenty of legal games, programs, books, music and videos that people can download using P2P programs. I know I do, because it's faster for me to download a freeware program from several thousand hosts rather than one heavily bogged down website.
Not everyone using LimeWire or other services are blatantly ignoring copyright laws.
