duuudes, 1 word: limewire. it does have adware, not very aggressive adware, but it does cause the occassional pop-up. you can get it at limewire.com, i think its the best p2p because its really easy to use, there are fast results, immediate downloads, fast downloads, and more search results than in any other p2p network. also, for those of you with the codec problem for wmp, just get wmp 10. i have it, its worth it, it comes with more codecs, and its pretty good. limewire returns mostly non-avi results, too. the only problem i found, other than the adware, is that if there are 2 or less sources, then it will say "Need more sources" this gets annoying, although the latest version allows you to "find sources."
