Avast loses folder exceptions to restart

Good morning , I’m new here on the forum , bought Avast but I’m having some difficulties to manage it, put some machines in the field and installed avast remotely the same , however, have an ERP system that avast "kills " the executable finding what a virus is , there will the way and place as an exception not to be scanned while the computer is on, functions normally , but if restarting loses this exception.
