    windows defender virus definition

    Thanks very much Andrew,

    not sure I follow you. The security scanner you suggested does not indeed find any malicious software on my PC. however this does not solver the issue of windows failing to download the latest virus definition. It still complains about internet connection.
    Also tried to remove Microsoft essentials as lacrumb suggested but it's not listed in my programs for some reason.

    Regards

    Nash

    Windows defender virus definitions update question

    With your Avast installed the real-time Defender protection is disabled, but it should still be available for an on-demand scan and should have kept its definitions updated.

    You should see definition updates listed in your Update History....

    ...and in Reliability History.
