SymUIAgent.app issue. Keep getting: You don't have persmission to use the app "SymUIAgent.app"

Hi - I recently installed Norton AV, Confidential and Firewall (via Comcast) on my Mac (running Snow Leopard).

 

I have a second account on the mac that is set up to use the mac parental controls.  Often when I log into this account, I get the message: You don't have persmission to use the app "SymUIAgent.app".  I choose "Allow Always" and provide the admin id and password.  It always asks for this twice, then goes away for a few weeks then starts the cycle gain.

 

I checked the forums which address this for users that installed Norton Site Minder.  I don't use Norton Site Minder.

 

Can anyone tell me how to stop these annoying popups?

Thanks.
