This is pissing me off. I work hard to keep a clean system and have been
using computers since the 70's. I have scanned my system with for virii and
malware and found nothing.

Any ideas what to check next?

Spammers often use incorrect return addresses when sending spam. Some
spammer may have acquired or guessed your email address, and started
using it as the return address when sending spam. In this case, there is
likely to be nothing on your computer that can be fixed to prevent such
mail again.

However, you can read the headers of the message originally sent and find
out where to report the spammer to, and probably get it stopped at the
other end.

Be careful about trying to report spam from unfamiliar providers
without doing a Google search for that email provider and making
sure they are an actual email provider and not a spammer that's
set up their own software to act as an email provider, though,
since such spammers often use the return addresses of any email
they are sent as addresses to send more spam to.

Deciphering spoofed headers correctly is not a trivial exercise.
Those who wish to complain to the admin of the sending
server should avail themselves of the free services of SpamCop.
