Firewall default settings help

I have noticed that EVERY time I start my computer that the setting for the firewall has
changed to HOME and not the setting that I last had it at which was WORK.

I tried to address this problem by writing a letter to tech service but was unable to
send my question … avast site would not let me enter my inquiry.

I would like to know how to tackle this seemingly simple problem . Why does the
program default to HOME setting ?

Are you connecting to the same network each time? I find the firewall does change when I switch WiFi networks
