Torrents for teh win....
...as others have said. However, if you must MUST lower yourself into the fetid pile of shit that is peer to peer filesharing, avoid Limewire, BearShare, Kazzaa etc etc. They are all virus ridden spyware stuffed pieces of excrement.

There is a freeware bit of software called Frostwire that's actually ok tho, so that might be worth a look if you want to spend 48 minutes waiting for the new Coldplay single to download only to find it's either corrupted half way through or is actually an illegal jpeg of an 8 year old's fairy closet.

Bittorrent wise, look at Isohunt, piratebay.org, or torrentspy. ABCtorrent is a good program for actually downloading stuff.

Another word of warning tho - if you are indeed totally clueless, avoid all of this. Its riddled with spyware and viruses and illegality and stuff. Once you properly understand virus checkers and spyware and stuff of that ilk, gaz me and I'll run you through it.
