What file for Avast Program Update

I don’t let programs do automatic updates, so after about a month with CFP3 I tried to check for an Avast program update and failed with a message saying not enough user rights to continue. If I disable defense + it works. I assume I need to give more privileges to some file that I haven’t yet done so for. Anyone know what file that might be? I don’t want to get carried away giving privileges to too many files unless they need them. I really don’t mind the occasional popup if I feel it gives me more control over what the programs on my computer are doing. Thanks,

avast.setup allows udp/tcp out under firewall, avast.setup and setup.ovr installer/updater under D+ is what I show.
