All P2P programs are gonna put you at risk and prolly at some point, give you a virus. Some are a little safer than others. For basic P2p, I ;ole limewire, but make sure you're virus software is updated and running when using that shit. The best by far is torrents. You can still get screwed, but it seems that most people don't seed torrents that are malicious. It's not hard to figure out. If you're behind a router and having trouble, then troubleshooting it will give you a better understanding of your setup.
