Odd, Norton had no problem with Nimda at work, haven't seen one in the logs for a while mind you, mostly KlezH & Yaha at the moment, plus one reported sighting of Sircam.

If it has you can get intelligent updater downloads manually at www.filelash.com Safest thing to do is ditch Outlook and get yourself a less vulnerable mail client. later jb
