I would like to ask where I can set up trusted networks in the firewall and if I can set them up at all. I found Friends, but I can not change any values there. There is a set range of 192.168.0.0 - 192.168.255.255. I just want to set some networks as trusted. Is it set up somewhere?

Update mirror is broken. My virus definiton is 170620-2 when update mirror is on. When I turn it off, avast updates databse on 170622-4.
Pc, where update mirror is set is connected to internet of course
