[DefCon]

I do not use outlook as a mail client.
I use a web-based mail service only.
I am getting fewer of these this week than last.
It was 2 0r 3 a day last week, only 2 or 3 total this week.
Some are messages with infected attachements.
Some are 'send' errors from various postmasters
rejecting mail that was spoofed w/ me as the sender.
I suspect somebody w/ the virus has my email address in their address book.
I tried warning my contacts, but most of them are not very computer savy,
and most of them just respond w/ a ?huh?.

I suspect somebody w/ the virus has my email address in their address book.

If you check the headers, you can find the ip address it came from (it will be the ip address in the Received From: line added by the first mail server it hit at your ISP - everything before that is a lie). You can take that and go to www.dnsstuff.com to find out which ISP owns that address. Forward it to abuse@ that ISP. They can check their logs and find out who it's coming from.
