Windows 10: Loads of System 32 folders have been blocked by windows defender

So recently I looked through my recently blocked folders by ransomware protection (Built in to windows defender) when I noticed loads of programs like MoUso core worker.exe and explorer.exe had been blocked from making changes which I find weird considering windows defender is an application designed by microsoft. What should I do?

Windows Defender is blocking too much saying it viruses

Hi Sam,

Based on the screenshot that you've provided, Controlled Folder Access is turned on, blocking most apps that you're using. We suggest that you turn it off to allow blocked apps in Windows Defender. Follow the steps below:

• Select Start > Settings.
• Choose Update & security > Windows Defender.
• Select Open Windows Defender Security Center.
• Select Virus & threat protection, and then choose Virus & threat protection settings.
• Under Controlled folder access, turn it on or off.
• Once done, try accessing the apps and see if you can now access them.

Should you need further assistance, feel free to post back.

Hi Aeolus0,



You can add allowed folder or apps in the Windows Defender Controlled Folder Access, as it basically blocks almost every changes when it is turn on. You may try to follow these steps to add allowed apps:

• Open Windows Defender Security Center then select Virus & threat protection icon.
• Click the Virus & threat protection settings.
• Click Allow an app through Controlled folder access.
• Select Add an allowed app, navigate and select the app you want to add, select Open then click Yes.
• You might be prompted a UAC to continue.
• You can click the Remove button if you want to remove the added app.
• Close the Windows Defender windows.

On the other hand, if you want to allow a blocked app in Windows Defender Security Center, you may check this

The DWORD is set to 0 and I cannot get the process you suggested in the "NOTE" portion of the tutorial to work. Two attached screen shoots will show the before and after attempts to change the Permissions necessary for access to the DWORD change.




Access is denied. (Note-Protected folder in Defender is turned off)
