How do I find out where an email REALLY comes from?

I have been getting some very clever email sent to me thanks to a virus.

The virus seems to be infected on someone's computer and is going through their address book and making a from line that is simular to the person it is sending itself out to.

For instance, if my email is complete@completetranslations.com, its from line says "admin@completetranslations.com"

the email says:

We regret to inform you that your account has been suspended due to the
violation of our site policy, more info is attached.

But my anti-virus program catches it:

The most you can usually get from email headers (to find out where the message came from) is the IP address of the sender. Sometimes you won't even be able to get that if it was sent through certain open relays. With that IP address, all you can really do is report it to the ISP and tell them that you are receiving these emails and then they may or may not do anything about it.
