    I assume its an update for Windows Defender?

    If so, I recommend trying to download and install the update via Get the latest definitions - Microsoft Malware Protection Center or via Windows Defender itself if not already tried.

    Yes it is an update for Windows Defender.
    I went to the website you indicated (thank you) but when I tried to download the update I got an error message saying Windows Defender was off. (see attached). When I clicked on start it said the app was not in a state to be started.

    I'm in 8.1 and I have Avast installed. Could that be the reason?

    Thanks again.

    Yes, when any third party virus application is installed, Defender is disabled...

    Thank you. I also use MBAM so I should be safe. I'll ignore the WD update.

    Usually when any third AV is installed you shouldn't get WD updates anymore.

    How can I tell Windows Update to add this update to the "ignored" optional updates so it doesn't present itself every time I restart the pc? Is that possible?

    I don't think it is possible, hopefully I'm wrong.

    I too hope you're wrong, but I think you are correct. 😩

    I have also noticed that KB2267602 is showing up in windows update from today.
    Beats me why because I have had Avast installed from day 1 on this computer, although I have just updated to their latest release (.2215) over the weekend.
    I wonder if the current Avast release has triggered the Defender update somehow ??
    I think I will ignore it for now and hope it 'disappears'.
