  1. Not Getting Defender Definition Updates


    I have Task Scheduler set to check for Defender definition updates every 15 minutes, which it is doing without interruption. The virus definition update history lists the last 50 updates and I usually receive 8-12/day. However, when I look at the definition update history, the last update occurred on 2/3/2020. Even when I check for updates manually, I am not receiving any definition updates. So, it is either that, for some reason, I am actually not getting the updates, or I am getting them and they are not registering in the virus update history. Also, there are no error messages. Any ideas?

    Windows Defender Definition Updates.

    Thank you Elba for the prompt reply. However, there is a problem: In "Control Panel" under the "Programs and Features" page > "View Installed Updates" the " Windows Defender Definition Updates" are NOT listed. Consequently, I cannot delete/uninstall them.
    The same thing happens when I use "Settings" >" Updates & Security" > "View Update History". Here the Definition Updates are all listed but I can't uninstall them either. Any other suggestions?

    Thanks again, Fred
