I installed the Norton Internet Security suite on my iMac (OS 10.5.8) 2 months ago and it been working very well. Today I attempted to launch the Antivirus GUI and I got a msg saying "Norton AntiVirus could not open its preferences." I found that all the Norton tools were saying the same thing. I rebooted, uninstalled and reinstalled but I get the same result.
I have downloaded and run the "special" uninstaller. This did not help.
Has anyone encountered this before? Any ideas?
