Download Shareazza. It's a freeware program w/o scumware/spyware. It is based on the Gnutella/Gnutella2/eDonkey networks. (As opposed to Kazaa - Fasttrack network). It tends to be a slower, but you can pretty much find anything out there. And the good news is that it also handles bittorrents. And I've never come across anything faster than a good bittorrent download once it gets rocking!!!
So once you have Sharazaa installed, just surf the web and find a good link. Sharazaa will pop up and your bittorrent download will begin. Easy as pie.
www.zeropaid.com has all kinds of info on P2P clients and you should find a link to Shaeazza there.
