Like I said, mIRC is safe for downloading since you don't 'share' files through it. It was designed to be a chat-program. Bittorrent, on the other hand, is like the most unsafe program when it comes to downloading since you share files as you download them and I've heard of quite a few people getting warnings in the mail because of sharing stuff through bittorrent. So use mIRC if you don't wanna get in trouble again.
