I'm not sure the 'bounced' messages are related to the latest PC virus.
That's exactly what they are--they are indeed related to viruses.
There are two kinds of bounce messages you will receive.
The first kind looks exactly like a bounce message, but isn't. It is a message from the virus designed to trick you into believing it is a bounce. The idea is that people are more likely to look at bounces. GIBE-F and SWEN/A are two viruses that send out messages disguised to look like bounces.
The second type is a real bounce, but going to the wrong place. Most mass-mailing viruses, including Gibe, Swen, Minmail, and so on, also send out email with a forged From: address. Here's how it works:
Say Joe is infected. Joe's computers send out infected emails. But the emails don't have Joe's name in the From: field. The From; field is forged with Bob's name. That way, if a mail server bounces the message, the bounce goes to Bob, not Joe. It's easy to fake a From; address; I can send emails that seem to come From; your email address if I want to. If the email bounces, I don't get the bounce--you do.
