    Windows update and windows defender issues

    We suggest you to avoid installing any cleaner or anti-virus software that may interrupt the function of Windows Defender. Make sure that Windows Defender is always on. To do this follow these steps:

    • On the Start menu, type Windows Defender and hit enter.
    • Click Settings.
    • Turn Real-time protection on.
    We also recommend you to install the latest update for Windows Defender.

    Should you have further questions, feel free to get back to us.

    Windows defender couldnot update

    virus and spyware definition couldnot be updated

    Did you restart the computer? Sometimes that will fix such update issues.





    What virus definitions are installed in WD?





    When did WD last install updates?

    Any other security program installed?





    https://support.microsoft.com/en-us...b59cebc4f24/how-to-protect-your-windows-10-pc
    Note the statement "If you want to use Windows Defender Antivirus, uninstall all of your other antivirus programs and Windows Defender Antivirus will automatically turn on. You may be asked to restart your device."







    The behavior you are describing may occasionally occur if another antivirus program is installed or there are remnants of a third party antivirus program still installed.





    Go to Security and Maintenance, look in 'Security' and see what program is listed under Virus Protection. Windows Defender will not be enabled and functioning properly if there is a program other than Windows Defender listed.





    Suggest you follow the steps recommended in Problems
    starting Windows Defender in Windows 8/8.1/10     to include (but not limited to) running SFC, scanning for malware with Malwarebytes and running the software removal tools for any
    security software (AVG, Baidu, Kaspersky, McAfee, Norton, whatever) to include a trial versions of McAfee or Norton that may have previously been on the computer followed by a restart of the computer? List of
    anti-malware product removal tools

    If you cannot resolve the issue suggest post back in this thread with further information.





    Alternatively - - -





    You may prefer to install a third party antimalware program (which should disable Windows Defender).





    There are a number of viable free and paid options available – take your pick…
