Which File Sharing program are you using?

For me, I'm using ARES. Thinking back I first started using Kazaa. It was like the greatest at that time. But that was few years back. Now it seem so useless. I tried downloading some stuff through it a few days back and whoa! The viruses just can't stop flowing into my computer.

I've tried using many other more File Sharing programs like BitTorrent, Limewire and so on. And until now none of them seem to be faster than ARES. I don't know what about you guys but I'm facing that problem. So far, ARES haven't seem to disapoint me yet. Hopefully it won't =)
