    Windoes defender has blocked access to my computer


    So, I was on Facebook, clicked a link in Facebook and Windows Defender appeared with all kinds of warnings and is telling my access is blocked for security reasons. Anyone know what this is?

    :)

    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.

    Block ALL Programs Except Allowed Ones

    You can block programs using Windows Defender, for example (ignore the strange title):
    Please Wait... | Cloudflare

    Turn On Windows Defender Block Suspicious Behaviors in Windows 10  

    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.
