Is there a virus on my pc

[system]

I also have had similar problems in the past (and continue to do so). Apparently, there is nothing I can do. My PC is clean, avast! scan is clean and so is MBAM. Gmail marks these e-mails from ‘me’ as spam.

From what I gather, other PCs / users to whom I have sent e-mail and am in their address book may have viruses / trojans which are spoofing the e-mail addresses. If I examine these headers, the e-mail is clearly not originating from gmail or my usual ISP smtp domains.

If anybody else has any suggestions to prevent this, I would be most appreciative.

no-if someone is spoofing you all you can do is report it to the ISP that it came from (pretty much useless)
