If you have been having trouble for that long there seems to be some issue with your installation.
Reinstalling with the Norton Removal and Reinstall Tool will give you a fresh install. Download the tool from www.norton.com/nrnr If you use Identity Safe be sure to back up your data in the CSV format. Run the reinstall tool. Be sure to run LiveUpdate manually, rebooting as necessary until no updates are available. Reboot once more and see if things are correct again.
Have that just abou five time reinstalled. But after about 3 housrs once again tessl me "you have Anti spy ware switched out", and iti is not possible "to fix".
After (any of many) RnR it seems few hours as working,
Than (this morning again) goes Antivirus out, with message "YOU have antispy detection switched out" :-) :-) .-).
Than at "Fix" are updates downoloaded (about 101 MB) a and installed (updates 1 to 8). But updatinf is not completed, and Antivirus is switced out, and scans no more.
Run the Norton Removal Tool. Reboot the PC afterwards. Install the Norton Internet Security 2013. Once installation is complete, uninstall the program using the add / remove program. This will clean up any mess that Norton Removal Tool fail to remove. Reboot the PC.
Run the Norton Removal Tool. Unlike the first run of the Norton Removal Tool, it shouldn't prompt you to reboot the PC at this stage. It will simply launch a browser window. Close the window and reboot the PC.
Go to C:\ProgramData and delete "Norton" and "NortonInstaller."
Reboot the PC.
Run the Norton Internet Security 2012 installer. Go to settings --> Web --> ID Safe and create a local ID Safe vault. AFTER you have done that, run the Norton Internet Security 2013 installer. Reboot the PC as prompted.
When the PC has rebooted, try importing the backup you created earlier by going to settings --> Web --> Identity Safe --> Import data. Browse to the location you save the .csv file. Click OK.
Run LiveUpdate until it says no update needed. Reboot the PC as prompted.
Once this is confirmed, reboot the PC to remove all the old files (I know that upon engine changes, there usually have two files. One is the old and the other is the new. Only a reboot will get rid of the old file).
My version (Norton Antivirus) is not downloadable (only NIS Norton Internet Security, or Try 30 days version).
Hope only, that at end of Ramadan comes my Antivirus programmer back to work, and corrects last version of Upgrades 1 to 8, which to time cannot to be O. K. installed.

Launch the program and make sure it's running 20.3.0.36 or later. As of March 6, 2013, Norton is currently holding back the 20.3.0.36 update for Norton Internet Security 2013. See the announcement here. This may change in the future.
