CONSTANT ERROR MESSAGE: “program trying to access email address information antivirus”

After recent updates to Outlook 2010 and Norton 360 [run on an Win 7 64-bit PC] Outlook no longer shows an active anti-virus program. And now I get this error message before it tries to check the mail: "program trying to access email address information antivirus".

How can I get Outlook to acknowledge the Norton AV module and stop these irritating messages?

Thank you!
