Windows 10: windows defender anti-virus protection disabled

my virus and threat protection displays a message "your virus and threat protection is managed by your organization". I do not have and organization to manage my virus and threat protection. There were several downloads allowed by One Drive, "file only" and two were anti-virus programs which I deleted but I still get the above message. Any ideas why this could still be happening?

Anti Virus Problems

You should not be using more than one anti-vrus program on your computer. Read the
IMPORTANT NOTE about not using more than one anti-virus program in this

topic.

The inability to turn on Windows Defender 8/10 is typically the result of having a third-party anti-virus installed or failure to remove it properly (completely). Since Windows 8/10 Defender includes anti-virus protection, it is
disabled during the installation of another anti-virus program. If a trial anti-virus (i.e. McAfee, Norton, etc) came
preinstalled on your computer or you installed one, Windows Defender will be turned off (disabled). Windows Defender recognizes the install and automatically disables itself when other anti-virus products are used
to avoid conflicts. Windows Defender will remain disabled until that anti-virus software has been completely uninstalled. In some cases, you may need to download and run the anti-virus vendor's clean up tool to remove any remaining
remnants.

After removal of the third party anti-virus, Windows 8/10 Defender needs to be
activated if you choose to use it. When uninstalling the third-party anti-virus Defender should automatically turn itself on but sometimes you may receive a message indicating
your system has no protection...click here to turn on Windows Defender. If not, and Defender remains disabled, you will need to manually turn it on.

Is Windows Defender the only anti virus program I need?

Clarification, please.

Note that this is a Win10-specific thread.

Are you suggesting that Defender in Win10 (and Win8) does not include an anti-virus component or are you suggesting that Defender in Win10 (and Win8) does not provide sufficient (adequate; comprehensive) protection?

 

Windows Defender Real-time Protection will not turn on

Did you follow the steps recommended in Solutions : Support



How about the steps recommended at http://www.bitdefender.com/uninstall/



Try running the removal tools for any security program that you previously used on the computer and be sure to reboot after using each tool. See
List of
anti-malware product removal tools



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