Transmission of viruses through encrypted e-mail

I am trying to find any information on viruses being transmitted through encrypted e-mail. I have not heard of any cases, but my upper management is concerned. We are rolling out MS 128bit encrypted e-mail for our users and use NAV for virus checking. Our NAV contact has told us that the NAV program on the individual PC should catch the virus upon opening the file, but we would like an outside opinion. Any information would be greatly appreciated.
NAV correctly configured for automated updates should catch any viruses sent through encrypted e-mail. Encrypted e-mail is nothing more than a secure pipe (or transport) from one point to another. Once the e-mail is received on your desktop/server, a virus would be detected if NAV is correctly updated and maintained.
