Que Puedo Hacer Si Mi Computadora No Prende

Hello Im trying to deploy avast through caspersuite to our macs when we image them and what not and its not working correctly. I was wondering how you guys do something like that? I talked to avast support and they said to use a repackaged installer, I am fairly new to mac so unsure on how to do that. is there a tool to use to do such a thing?
