I installed TDR, and noticed folders named “!TDR.bin” and “ΩTDR.bin”. What are these?

    These folders are part of TDR’s Host Ransomware Prevention detection service and are normally hidden. If the Host Sensor detects changes to these files, the Host Sensor reports the event back to TDR as possible ransomware activity.
    Change the Hidden Files Setting in Windows
    If you have previously configured Windows to show hidden files, you can change this setting so that the decoy files are not visible on the Windows desktop and user folders.

    To change the hidden file setting in Windows 8 or Windows 10:
    1. Open File Explorer.
    2. Click View **to show the View ribbon.
    3. Clear the **Hidden Items     check box.
    To change the hidden file setting in Windows 7:
    1. Open File Explorer.
    2. Select Organize > Folder.
    3. Select Search Options.
    4. Click the View tab.
    5. In the Hidden files and folders settings, select Don't show hidden files, folders, or drives.
    For information about other methods to change this setting, see the Microsoft Knowledge Base article: : Show hidden files.
