Norton Remove and Reinstall did NOT make a clean reinstall

Hi.

Win (10) Update keep on DL Defenders updates and, tries to install them resulting in ERROR message.

Probably caused by the below Registry post:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows Defender

Name                Type            Data
DisableAntiSpyware        REG_DWORD        0x00000000 (0)
DisableAntiVirus        REG_DWORD        0x00000000 (0)

Should be:

DisableAntiSpyware        REG_DWORD        0x00000001 (1)
DisableAntiVirus        REG_DWORD        0x00000001 (1)

But, when I try to "Modify.." (RegEdit) I'm not allowed to do that - Even as ADMINISTRATOR!?

How do I fix this manually - Anyone have a clue?

 

B.t.w. what is this (Registry):

RemediationExe            REGT_EXPAND_SZ        %ProgramFiles%\Windows Defender\MSASCui.exe?
