I have tried everything but for some reason my windows defender is broken and I cannot find a fix short of a refresh of the OS

It says "Your PC couldn't be scanned. Some history items could not be displayed. Please wait a few minutes then try again. If that doesn't work, clear the history and then try again."

under my history there is nothing ..

As Mr. Boots said, it may be a disk error.  Alternately, some files Defender requires may be corrupted.

  1. Disable Windows Defender in Settings tab under Administrator section
  2. Delete the folder C:\ProgramData\Microsoft\Windows Defender\Scans

It may be hidden, and will require elevation to access it.

  1. Enable Windows Defender using the Security Center notification on your task bar

When you enable Defender, the files should be recreated.

    In order to delete the Scans folder, you first must take ownership of the folder. you can do this pretty easily...

    Right click the Scans folder, and choose properties

    In properties, click the security tab

    click advanced at the bottom of the security tab

    in this window, it will tell you the owner is SYSTEM with a link to change that

    Click the "Change" link in this window, and take ownership of Scans, and all sub-folders, and files

    Once done, click ok on all those new windows, then you should be able to delete the Scans folder.

    I have this problem also and i cant seem to delete the scans folder it tells me 

    You need permission to perform this action

    You require permission from SYSTEM to make changes to this folder

    Scans

    Date created 23/08/2013

    but before i get this message it seems to say x amount was recycled but it goes really fast.

    Any ideas why?

    Cheers,

    I have now got the new Windows 10 and i thought it would fix this error. I just received the error now :( Its driving me insane as i have to do a full scan to get me back to protected mode.  I hope someone can help.

    Thanks this essentially worked - I used the take ownership button under my context menu to take ownership of the folder, delete it, and then scanning worked. Thanks 

    Great -- thanks for confirming.
