I did eventually found the correct menus. In case of someone else is recently switched from another AV-product to Avast! as Me. Here is short guide how to repair and exclude.

  1. From Avast! main menu go to MaintenanceVirus Chest
    At Virus Chest Click with right mouse button the line:
    BrCtrCen.exe | C:\Program Files (x86)\Brother\ControlCenter3
    (I got many of the above lines because of multiple driver re-installation attempts they were located just in different directorys)
    Select the Restore option from pop-up window.

  2. Then go to REAL-TIME SHIELDS menu and click Expert Settings button next to the right border.
    From a new pop-up window select exclusions menu and add the the directory mentioned at phase one to the excluded directories by clicking small add button at bottom of the window.

  3. Reboot and Brother control center should be back up.
