Windows 10: Defender reports a zip virus on github download but no explanation nor protection history

When requesting a zip of the master the download is refused and a warning pops up and then goes away. Looking at defender I cannot find what the problem is. Nothing in protection history and looked everywhere I could think of.smart app control is disabledI looked in the event viewer alsoI have no idea why a no-name virus is reported.I can tag and publish and the download zip from the publish or tag download fine, no virus warninggithub desktop can download the entire project, no warning.Just cannot ask for a zip. I am guessing something in the zip caused the problem, but I have no idea how

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.
