    How to Update Security Intelligence Definition Version for Windows Defender Antivirus in Windows 10


    Windows Defender Antivirus is a built-in antimalware solution that provides next generation protection for desktops, portable computers, and servers.

    Windows Defender Antivirus uses security intelligence to detect threats. Windows 10 will try to automatically download the most recent intelligence via Windows Update to protect your device against the newest threats.

    You can also manually check for updates. A manually triggered update immediately downloads and applies the latest security intelligence. This process might also address problems with automatic updates. Windows Defender Antivirus and other Microsoft antimalware solutions provide a way to manually trigger an update.

  2. Security Intelligence Update for Windows Defender Antivirus - KB22676

    I just checked my PC and I got exactly the same Security Intelligence Update as you. It was pushed through Windows Update about 30 minutes ago. Prior to that I also had two standard Definition Updates for Windows Defender Antivirus earlier on today

    Security Intelligence Update for Windows Defender Antivirus - KB22676

    Is this new? Just got what I thought was a Defender Definition Update, but the name seems to have changed now to
    Security Intelligence Update for Windows Defender Antivirus. Same KB number, same numbering sequence, just a name change. Even Reliability History show some with Windows Defender Update today, then this one just now.

    Not a Platform Update, that remained at 1907.4.

    Anybody else?

    Security Intelligence Update for Winodws Defender Antivirus - KB226760

    Hi, might not be your PC:
    Windows Defender Error 0x80070643 Updating Definitions >> Winhelponline

    This page also gives ways to update manually meanwhile.

    And Defender is there but not as a real-time AV if you have another installed. Note this option e.g. (I have Avast and SecureAplus installed - the first is real time, the second something quite different- no conflict)

  6. Old "Definition update" = New "Security intelligence" ?

    Hi Laur

    My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

    Microsoft changed the name from Definition Update for Windows Defender Antivirus to Security Intelligence Update for Windows Defender Antivirus around the end of July.

    So, what you are seeing in Windows Update is safe.
