Hello @RaymondP_McIntosh
was LiveUpdate toggle switch off…after running NRnR tool?
and you’ve since called an extra Restart (not Shut down) machine since running the NRnR tool?
Have you reviewed LiveUpdate → Security History for ~24 hours to confirm?
Maybe, you need to run Norton 360 Remover → Remove only…for clean uninstall → clean install.
=============================================
Download and run the Norton 360 Remover tool for Windows here
fwiw ~ my preference is Remove only…with scour File Explorer for remnants and CCleaner - Registry - Scan for Issues + CCleaner…back up the registry before making changes. Just me.
