Hello @Radarman
Does running Norton LiveUpdate + Restart (not Shut down) machine help?
=============================================
fwiw ~ my boiler plate:
If your Norton is not working as expected and you’ve tried Troubleshooting → Reset to Default &or Repair Norton & clean re-install Norton 360…then…reach out to Norton support.
Note: Reset to Default resets Cloud Backup
Norton 360 Remover tool for Windows here
fwiw ~ my preference is Remove only…with scour File Explorer/Registry for remnants. Just me.
-----------------------------------
Maybe, try Troubleshooting → Record a performance issue &or Enable/Send debug logs
