So... sorry, but it's too late! You're
joining the thousands of other
folks in the same fix.
And, the more you've posted, and the more your messages have been saved on
people's PCs, the more virus/worm messages you get. I had to disable the
e-mail address that I'd had for years and had used un-disguised in my
newsgroup posts -- the mail server was getting multiple tens of megabytes of
virus/worm e-mail for me every day.
I broadcast a message to everyone in my secure address book (not in OE nor
Outlook, because I don't want to be the source of such mail on the offchance
that my computer became infected) and they set up an AutoResponder for a few
days -- it sent a message that was easy for human to determine what the new
address was, but not easy for a spam-bot getting a returned message to
extract. So far, I've had neither spam nor virus messages to the new userid,
and you won't see it in my headers, anymore, either.
