Once removed, manually remove any folders on drive C:\ that are labeled Avast, Norton, Norton installer and reboot. These are sometimes not removed by the uninstaller.
Next, log into your Norton account, download a fresh installer from there and re-install your product again. You hopefully should NOT get any errors. If you do get a screenshot of it so that we may review it for you. Here is how to get and post screenshots:
If you do not have errors. Live updates should run automatically at least once. If, it does not, manually run it and install whatever updates are available. Reboot when done. After this reboot recheck live updates a second time. If no updates are available you are good to go.
