The remove button is greyed out for some items or applications in the App and file control’s Excluded tab in the Client Security or Server Security user interface

Issue:

The remove button is greyed out for some items or applications in the App and file control's Excluded tab in the Client Security or Server Security user interface.

Resolution:

The Remove button in the App and file control window's Excluded tab can be grayed out and unclickable for specific items or applications on the list because the exclusion has been created by an administrator as a policy distributed from the Policy Manager Console. You can ask your administrator to remove the exclusion. 

In the Policy Manager Console, the exclusion can be removed like by following these steps:

1. Open the Policy Manager Console
2. Select a host or policy domain from the domain tree
3. Go to the Settings tab
4. Navigate to the Windows > Real-time scanning settings page
5. Scroll down to the Files and applications excluded from scanning table
6. Select the file path from the list 
7. Click Clear row
8. Distribute the policy (Ctrl + D)

The Remove button can also be grayed out and unclickable if the administrator has prevented local users from creating exclusions locally on the devices. To allow local users to add exclusions:

1. Open the Policy Manager Console
2. Select a host or policy domain from the domain tree
3. Go to the Settings tab
4. Navigate to the Windows > Real-time scanning settings page
5. Scroll down to the Files and applications excluded from scanning table
6. Uncheck the Prevent users from adding scanning exclusion option under the table
7. Distribute the policy (Ctrl + D)
