Good thread, this, and my thanks to those who flagged up the problem.
Updated my McAfee Viruscan yesterday (27th Nov) with the 21st Nov DAT file and checked the setting to scan all e-mails and downloads. Got my copy of the virus this AM from "Milan Galant" with no subject message - just the "Re:". Virus scan spotted it before opening and stopped me in my tracks. Told me the name of the virus and what to do.
Now, it is just possible that there is a connection between the update and the attack, isn't it...? No, I'm just being cynical. But what better way to convince the customer that he has bought a good product?
McAfee's Web Site must be one of the worst in the World for pushy marketing but as far as I know, the Product is OK.
