    I recently got a new PC running Windows 10. I am using Defender for now, I am switching later on and it keeps blocking almost every app that is downloading or trying to access my files. These apps are trusted sources. It happened on some apps like Lightworks, paint.net, and even notepad.exe and my manufacturer processor app AMD. It even blocked an app from trying to access my memory. It's weird how it said that my administrator blocked this action even though I'm the administrator. Is it talking about TrustedInstaller or some other thing? This is really strange!! These are some screenshots.

    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.

    windows defender blocks programs

    You shouldn't disable Defender completely, it's protecting you against viruses and malware.

    The bit of Defender that's causing you grief is its Ransomware protection, or Controlled Folder Access as it is also known. This blocks access to certain protected folders (mainly your user folders) for any unknown or untrusted apps.

    While Defender has a whitelist of many apps it trusts by default, there will inevitably be some perfectly safe apps that are not on that list (yet). Your Open Office and my Libre Office are both 'unknown quantities' as far as Ransomware protection is concerned.

    You could turn off just the Ransomware protection, but that is leaving your files and documents less protected.. It is better to allow access for each app that's currently being being blocked. The easiest way to do that is Option One in this tutorial.

    Add or Remove Allowed Apps for Controlled Folder Access in Windows 10
