Issue

Active Protection blocks legitimate applications

Solution

Operations with Acronis backups

If you attempt to move, rename, delete or modify Acronis backup files in Windows Explorer, Active Protection asks whether you want to allow the Explorer to perform operations with backup files. Click Allow to permit Explorer to modify the files.

If you click Deny or do not click anything, by default any operations with Acronis backups outside of Acronis software user interface are blocked.

An application was blocked from modifying Acronis True Image settings

If Active Protection reports that an attempt to modify Acronis True Image files or settings was blocked, and you trust the corresponding application, usually you do not have to do anything and just ignore that message.

However, if you absolutely need allow modifying Acronis True Image registry and configuration files outside of Acronis user interface, you can disable the self-defence feature of Active Protection. Click here to see how.

2. Click on the Active Protection tab
3. Click Manage processes button:
   
4. Click Add button in the bottom right corner:
   
5. Browse to the executable file, select it and click Open:
   
6. Permission should be set to Allowed to start:
   
7. If later you need to remove the application from the list, move the mouse cursor over it. The option "Remove" will appear. Click it to remove the application from the white list.
   
    

Acronis True Image 2018: how to whitelist the executable

If you know what executable file was blocked by Acronis Active Protection, you can add it to the trusted list.

1. Launch Acronis True Image
2. Click on the Active Protection tab
3. Click Manage processes link:
   
4. Click "Add button" in the central left part of the interface:
   
5. Browse to the executable file, select it and click Open:
   
6. Verify that the status for the added application is "Trust":
   
7. If you will want to remove the application later from the list, move the mouse cursor over it. The option "Remove" will appear. Click it to remove the application from the white list.
   
   Please note that the white list is respected only by the ransomware detection component. The self-defence module ignores this trusted list, and if you need to allow an application modifying Acronis True image settings, you need to disable the self-protection as explained here.
