I'm sorry about the issue. Is this issue occurring with your Norton program?
Have you shut down / restarted the computer and check yet?
Please try a possible fix below:
Open your Norton program.
In the main window, click Security, and then click LiveUpdate.
When Norton LiveUpdate is finished, click OK.
Run LiveUpdate until you see the message, "Your Norton product has the latest protection updates."
Exit all the programs, and restart the computer, then check.
