Keep your Norton device security up to date
LiveUpdate keeps your Norton protection up to date and helps safeguard your device from evolving cybersecurity threats. Your Norton product runs LiveUpdate to install the latest security updates as and when new updates are made available on the Norton servers.
By default, your Norton product downloads and installs the latest definition and program updates regularly from Norton servers to help protect your computer from new threats.
If you turned off Automatic LiveUpdate or have been offline, you can check when you last received Norton device security updates and run LiveUpdate, if necessary, to assure that you have the latest:
-
Virus definitions that help protect your device against malware, unauthorized network access, spam emails, and much more.
-
Program updates that extend operating system or hardware compatibility, adjust performance issues, or fix program errors.
Security updates are available to you as long as your subscription is active. If the product displays your subscription status as expired, you may not be protected from emerging threats.
Check when your Norton product was last updated
-
Open your Norton device security product.
-
On the left pane, click Security.
-
In the Security dashboard, in the LiveUpdate tile, click Open.

Common LiveUpdate problems
A back-end service outage can stop LiveUpdate. To identify if there is a service outage, check the Norton Service Status page. In such cases, try running LiveUpdate after some time.

LiveUpdate running the first time after installation usually takes more time to complete
-
