When I open Outlook, Iget a lot of ';returned mail';?

Nothing shows up in my ''sent mail'' area. Over past few weeks I have received several hundred returned mails.

I usually use Mozilla and have Norton for my ''protection''. I have used the Norton technical support chat (for about $70 one time fee) 4 times to no change! They take control of my computer and use programs such as ''hijackthis, smitfraudfix, killbox.net''.

The returned mail all use variations of my address (meaning prefixes which I do not have, most are random letters)

I started to receive a ton of regular incomming mail prior, with the same theme. They all have a ''hot'' stock tip. It shows a multi-colored text area on top, below that box are several paragraphs of text which is all cut up as far as the subject goes.

And yes some do have attached files of which I never opened. Both Yahoo mail and somtimes Norton would detect viruses and not allow. Sorry for the long msg, hopefully this has been seen by someone!

Thanks in advance for any ideas.

One of two things for the most part.

1. A spammer is using fake NDR messages in an attempt to get past SPAM filters.

2. A virus is doing the same thing.

In either case, there's not a lot you can do. Just delete them without opening them.
