blocking unknown programs that attempt to "phone home"

Hello All,

 

I am running Norton Internet Security 2011.

 

I am familiar with Settings==>Network Settings==>Program Control, which can be used to block internet access for a KNOWN program.

 

Is there a way perhaps to set up a pop-up that will tell me if some UNKNOWN program tries to "phone home"?

 

Thanks ahead of time!

 

Best Regards,

Bob
