    Windows Defender - Security Warning


    I received a Windows Defender Security Warning. Trojan Spyware Alert - Error Code: #0x268d3. My computer is now locked. The pop-up box says to contact Microsoft immediately for assistance in unlocking. Do not attempt to logout or re-start as this could lead to loss of data or identity theft. Was on hold for 2 hours and phone battery died. Any suggestions on how to unlock without any danger?

    :)

    Microsoft rearranged the deck chairs again. In Win10 1703, Windows Defender Security Center is not the same as
    Windows Defender Antivirus. [sic] See

    Windows Defender - Security Warning

    windows defender & security center services keep turning off


    Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

    If you are getting any error codes please list those, that will be helpful in helping you.

    As torre suggested, might be a good idea to do a reset or even a reinstall.

    Windows 10 - Clean Install - Windows 10 Forums

    There are also some suggestions listed here:
