beeuuem , your link doesn't work for me. If you have another laptop/pc you can get online then download the removal tool, from here , heed the warning if you run the other programs and make sure you have your licence key handy for reinstalling. Copy to flash drive and copy it to your desktop on the non working PC. Run the tool and reboot. Check internet connection and repair if necessary. Reinstall Norton.
