    Connection lost during Defender Antivirus KB2267602 install: cannot delete for reinstall

    Is KB2267602 installation required?

    Today I looked at my Update History and noticed the following regarding KB2267602:

    "Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.291.1488.0)(2)

    Last failed install attempt on 4/9/2019 - 0x80070643"

    I have seen some locked threads on this subject and am not sure whether to try and download it, if possible, or not. I can't find KB2267602 listed in my list of Installed Updates. I use Norton Security Premium and have the
    periodic scanning turned off in the Windows Security - Virus and threat protection section. (Maybe that is why it didn't update, or do I even need it?)
