No. But..if you exchange files with PC users it's a good idea to scan them with Virex. (Which unlike Norton Antivirus for Mac *will* detect PC viruses.) That way you can at least let them know about it. As for keeping virus definitions up to date, that's only half the battle. Even with the latest definitions you still need to scan the drive regularly in case something slipped through between the updates. -- T. Patrick Henebry tphenebry at comcast.net
