The Quick Menu System Preference Pane in 10.6 is blank. There is no way to disable Quick menu.
That sounds like a bug in System Preferences. The QuickMenu is 32-bit still ,but when you launch System Preferences it should re-launch itself in 32-bit mode.
Try loading System Preferences from your Apple menu, and click on Norton QuickMenu. That should force System Preferences to re-launch in 32-bit mode.

Had to fully uninstall via command line script and reinstall. All is good now.
