URGENT HELP PLEASE - Symantec Email Proxy

I really hope I am not infected, but a little worried.  Here is my system:

 

Windows Vista x64

Norton Internet Security 2009

Email client:  Microsoft Outlook 2007 (using Outlook Connector to connect to MS Hotmail account)

Recent install:  Microsoft Sync Center (for my new Blackjack II cell phone)

Using Firefox 3.0.5 w/ AdBlock Plus and NoScript

 

Lately I am getting the following error come up on the screen when I am not using email:

 

Symantec Email Proxy cannot scan your email messages because your network is not properly configured. 

 

Now, what I've read online leads me to worry this might be a virus, except all of the messages I've seen so far online have the following number underneath:  "1003, 13.  In my situation, the number is "1003, 16".  Not sure if that makes a difference or not.

 

Not experiencing anything else that would lead me to think I'm infected (no slowdowns, Hijack This log doesn't show anything unusual).

 

Is anyone else getting this?
