Run LiveUpdate
Applicable for: Windows
LiveUpdate keeps your Norton protection up to date and helps safeguard your device from evolving cybersecurity threats.
If you turned off Automatic LiveUpdate or have been offline, check when you last received Norton device security updates and run LiveUpdate, if necessary, to ensure you have the latest virus definitions and program updates.
Make sure that you are connected to the Internet.
When running LiveUpdate for the first time after you install your Norton product, it may take longer than expected. Please wait while LiveUpdate downloads and installs all the available updates.
Run LiveUpdate to get the latest Norton product updates
-
Open your Norton device security product.
-
On the left pane, click Security.
-
In the Security window, in the LiveUpdate section, click Open.
-
In the Norton LiveUpdate window, click Update Now/Check Now.
-
When Norton LiveUpdate finishes, click Done.
-
Run LiveUpdate until you see the message, "Virus definitions are updated".
-
Exit all programs and restart the computer.
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.
Check for the following easily fixable issues that often cause LiveUpdate problems:

Your computer is not connected to the Internet

LiveUpdate running first time after installation usually takes more time to complete
-
Your computer has insufficient disk space
-
Your computer's date and time are not correct
