What kind of files are you finding with Trojans? I download all kinds of stuff on Shareaza and I never find any Trojans and I have McAfee... I also use Bittorrent all the time and never find any viruses in anything I download off of there either. The thing about bittorrent is that it is a community and anything containing viruses won't be around long cause it will be reported and the torrent then removed from the site.
