tried the various solutions on google still the same. This command will scan the system for the corrupted files and replace them.Malware can also be equally responsible in preventing the update of Windows Defender.Whilst it was reported that Norton was installed I did not know if this would cause problems.I uninstalled Norton then returned to the Security Settings and turned off WD before reinstalling Norton.
