Problem with Keychain Access after Re-Installation NAV 11 under 10.6.2

I just installed OS 10.6 to a new MacBook Pro and migrated programs and settings from my old Lap with OS 10.5.8.

 

When starting AV or LiveUpdate, a message appears saying that LiveUpdate or Norton Antivirus or IRTools want to use the "Symantec" keychain in Keychain Access and need a password. Admin password or the Symantec Subscription Key seem to be wrong. When canceling, the message appears another 3 or 4 times, then the updating process seems to proceed correctly. 

 

I made a complete uninstall with "RemoveSymantecMacFiles" (as Ryan, 1_10_2010 suggested  in this forum) and reinstalled NAV11 but the problem is still there.

 

Any suggestions?
