Now your Norton antivirus is activated and ready to protect your device from virus attacks. You can also activate your product directly by clicking on Norton.com/nu16 but you are required to have any subscribed product from Norton family. Activation will offer your real-time defense by turning on firewall security. This will block all the malicious web pages and reduce the risk of data loss.
If you are experiencing any error while updating or activating Norton product, go to the link Norton.com/nu16 and this will automatic download the file. Alternatively, you can first uninstall the antivirus to remove any kind of file error, and then re-install it by using Norton Product key. Go to Norton.com/setup and reinstall Norton Setup to eliminate Norton errors.
