    Windows Defender Threat Definitions Update?


    Normally by this time of day I've had one or two definitions updates. None since last night late:

    I do a manual check regularly. I've noticed that in the past week or so MS seem to have gone for only one update per day. I've just checked again. Your 1.245.577.0 still checks out as being the latest version.

    Thanks for the info and time. I guess I'm just a little paranoid and it shows now and then.

    For the really paranoid who don't trust windows update to get it right, you can manually download and install the definitions from here...
    https://www.microsoft.com/security/p...tions/adl.aspx
    ...makes no difference though, you'll still get 1.245.577.0 (I've just tried)

    Apparently if you are a business customer running Windows 2016 Server...
    Windows Defender AV issues new definitions every 2 hours...
    https://social.technet.microsoft.com...nderATPPreview

    That would explain why the version number seems to have a big jump each time, on that basis I would expect the next one to be 1.245.589.0. Us mere 'consumers' only seem to get a daily update (would you really want them arriving every two hours?).

    I was wrong (but not by much). 1.245.591.0 is today's update. Tomorrow's to be 124.603.0 (or there abouts ?)

    Mistyped - I meant 1.245.603.0 of course. As a new one is issued every two hours and it appears that one gets published to windows update once a day each should be 12 higher than the last (with a little variability for early/late release).
