Nothing like that is running. I don't have limewire but do use utorrent. As far as I know that isn't running at all atm.
I use uTorrent, too.I get data transfer even when uTorrent isn't open, but only if I have uTorrent's port opened on my router. So I generally don't bother with port forwarding any more. uTorrent still works, and its no slower for it.
