Avast Firewall

I spend a Lot of time locking down my computer with the Avast Firewall to my Very Strict parameters.
My Avast is Password protected with a complicated password, in fact 2 separate passwords just for Avast.
Ad yet Somehow all my Firewall settings keep being changed to allow intruders.
My Family Never touches this Passworded computer as it also controls our home network and they live for the internet.
I don’t think I will be renewing my License.
This is not up for discussion.
Thank you.

when you change avast firewall settings do you reboot after?

still same problem?

Yes I always reboot especially with Windows.
My access point to the internet is Protected by pfsense fully loaded Snort etc, No internet access, only Console Cat6 to Router ( DD-WRT soon) then this PC.
