Windows 10: My virus protection - Defender - on Windows 10 is out of date.

I'm getting notifications that my virus protection is out of date. "Security intelligence" says I can "manually check for updates." When I do that a graphic starts to spin and says "Checking for updates . . . * but it never updates. I've tried it several times.

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.

How to turn on Window Defender virus protection.

I installed Malwarebytes Anti-Malware. Now my Windows Defender is turned off. I need the virus protection but am unable to turn on Defender virus protection. I am using Windows 10. Any suggestions?

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.

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

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