HI all,

After installing Norton Security I always receive this error code using Windows Update: Windows Defender – KB2267602 (definizione 1.225.2575.0) - Errore 0x80070643

This error is related to Windows Defender that is not enable and not disable at all , the application is in CRITICAL state , the service WinDefend is STOPPED but I could do nothing, Enable it or Disalble the automatic launch.angry

Anyone has this problem or a solution ?

I prefer avoid to uninstall Norton Security but maybe this is the only solution. frown

Thanks to all !
