    Just received a new definition update, and quick scan appears to be normal, I think. *Smile

    The article is misleading in stating that...

    The bug affects ALL Microsoft's scan engines in ALL supported OS, that's Defender and Microsoft Security Essentials in Windows 7, Windows 8.x and Windows 10. It appears that the virus definitions are the cause of this bug. The bug is in ANY Microsoft AV that uses a virus definition from about 1.301.1600.0 or newer.


    Here I demonstrate the same bug in Windows 7 using MSE.

    If your manual Defender scans are failing, it's not you --

    Confirmed. The bug is fixed with definitions 1.301.1684.0
