Stopping Protection Center from Alerting Firewall Status

I have Norton Systemworks Basic Edition 11.0 installed and running on my Vista system without any other Symantec products.  The Norton Protection Center shows an alert which is related to my not having PC-cillin Internet Security Firewall (came with the PC) activated.  I've chosen not to turn it on because of its interference with Windows Media Center.  The Windows Firewall is being used, however.  Is there some way to have the Norton Protection Center program ignore that fact?  I'm tired of seeing an alert regarding something about which I'm already fully aware.

 

Thanks.
