I use Azureus Vuze (
www.azureus.com ) I get most my downloads from Pirates Bay or mini nova...Download Vuze and install and set it up. Then visit Pirates Bay or Mini Nova click on some thing you want to down load it will auto start the Vuze..The file will be zipped so you will need winrar or equivalent to unzip it..once you do that make sure you scan the file with AVG or similar to insure a clean DL...I used Limewire and man it really messed my computer up with trojans/virsus.IE Hacks
Few tricks on using bit torrents look for those with high seeder counts as it will speed up a download, read the comments left by others as sometimes there will be a dirty focker who puts a virus in there or its a shitty DL
Hope this helps good luck!
