Cojo,
Not a problem. Keep it up and we can give you your own forum. hahahaha
Not to worry. Bell South Mail Guard works on messages coming into their mail server. Apparently, the infected message was cleaned before it was downloaded to your computer (that is what a mail client like OE does).
Naturally, since you have OE set to prevent opening attachments, you received the warning that OE prevented the attachment from opening. Sounds logical...right!
Sometimes, ISPs take down their systems without telling the users anything. The main thing is that everything is ok now.
Avast should be fine. Bell South Mail Guard got to the virus before Avast had a chance to scan it, so you actually have layered protection.
Rest easy.
