Chuck. We will probably never find out where it started. At one point Gene and I received the same virus email from each other at the same time! Both our machines were definitely 'clean' at that time. As well as NAV my machine sits behind a 'firewall' which 'stealth blocks' all ports in both directions when not in use. The firewall 'vets' everything. I can verify that by the fact the IP address that accompanies my posts is the firewall address and not that of any of my 3 computers. The address is the same whichever machine I am using.

The chances are that whoever has the 'virus' was the originally the recipient of a mass mailing which contained all our addresses and that we all receive these same emails simultaneously.
