  1. Can't update virus and protection updates from Windows Defender.


    For a while, maybe 3 or 4 years I was using Norton as my anti-virus software of choice. A few months ago I ditched it in favor of the free Windows Defender. However, after it warned me that the threat protection was out of date, I decided to update it. The problem. It seems to be broken. I have waited several hours for it to "update". I have attached some screenshots of what I am experiencing.

  2. Cannot turn on Windows Defender virus protection

    I had the same sort of symptoms. In the Windows Security Center, under Virus and threat protection, it said "Your virus & threat protection is managed by your organization."

    I note you mentioned the Registry Keys under HKLM/SOFTWARE/Microsoft/Windows Defender. Nice spotting, but it seems like there is another key that is causing the problem for some users.

    Steps to a solution:

    1. Press the Windows key and type "regedit"
    2. On the regedit icon that appears, right-click and select Run as Administrator.
    3. Navigate to the folder located at HKLM\SOFTWARE\Policies\Microsoft\Windows Defender (You can paste this into the address box at the top of the window, or navigate manually using the side directory structure)
    4. In this folder, there are probably two keys. Right-click and Delete the DisableAntiSpyware key.
    5. Exit regedit, and return to the Windows Defender settings screen (refresh it if necessary). Windows Defender should have the scan options available and working.

    Solution adapted from here, with a much more detailed solution here.

  3. 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.

    Can't update virus and protection updates from Windows Defender.

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