    Hello, Thank you so much firstly. I ran the fix list, here is the fixlog: https://drive.google.com/file/d/1x97wFQDE7DLZI3WFxyrsMi6uW7EpDl0n/view?usp=share_link

    If I also have a x32 folder in my program files, should I ran the frst for that as well?

    It looks like you've uploaded fixlist.txt instead of fixlog.txt.

    Hi Andrei,

    Please run the fixlist below.

    • Download fixlist.txt
    • Save Fixlist.txt to the folder where FRST64English.exe is located.
    • Close all programs.
    • Launch the Farbar Scanner tool and click "Fix".
    • Restart Windows when prompted.
    • Upload the output log file (FixLog.txt) to your OneDrive.

    Do you know how to get rid of the files that caused the problem? And also, if I do the steps you wrote above, is there any possibility to lose data?

    Hi Andrei, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.

    I understand the issue you have, nothing to worry I am here to help, This happens when there is a corrupted file on the Windows Defender folder or a reconfiguration is needed, for us to sort out the issue, kindly follow the steps below:

    Method 1. Reinstall Windows Defender

    Open the registry, then go to

    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

    Then delete the Windows Defender folder, restart the PC, and recheck it.

    If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

    Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/402753...

    1. go to this link: https://www.microsoft.com/en-us/software-downlo...
    2. Select Download Now, and select Run. You need to be an administrator to run this tool.
    3. On the License terms page, if you accept the license terms, select Accept.
    4. On the What do you want to do? page, select Upgrade this PC now, and then select Next.
    5. After downloading and installing, it should fix the issue.

    Reference: https://www.microsoft.com/en-us/software-downlo...

    Let me know how it goes and I hope that helps.

    Bernard
