Troubleshooting in Norton AntiVirus for Macintosh Protection problems
In Mac OS X v10.1, Norton AntiVirus scans only those files for which your account has access privileges. You can do one of three things:
If you ever log on and work as root, run the scan while logged on as root.
If you do not log on as root, running the scan while logged on as an Administrator scans all files that could be infected while using that logon. If you do not want to see the list of files that could not be scanned because of denied access, check Do not list permissions errors when scanning in Preferences.
Restart your computer from the Norton AntiVirus for Macintosh CD and scan your computer using Norton AntiVirus for Mac OS 8.1-9.x to avoid access problems.
I need to rescan files that have already been scanned
The Norton AntiVirus QuickScan file records whether you have already scanned a file using the currently installed virus definitions and libraries. If not, the file is scanned. If you want all files to be scanned regardless, you can use Norton AntiVirus to delete the QuickScan file at the root of each disk. The file is named NAV• 7.0 QuickScan in Mac OS 8.1-9.x and NAV• Mac800QSFile in Mac OS X v10.1.
To remove the QuickScan file
In the Norton AntiVirus window, on the File View tab, ensure that Show Invisible Files is checked.
Select your hard disk.
Click the QuickScan file. If there are QuickScan files from previous versions of Norton AntiVirus, select them as well.

Click Move To Trash. Click OK. Quit Norton AntiVirus. In the Finder, click Empty Trash.
After you have deleted the QuickScan file, the first scan with the new virus definitions will be slower.
