Win 10pro/64-1909; after installing NIS, I added to the firewall some apps new rules and everything was ok, the firewall allowing to make changes without any special user confirmation; I also added new trustworthy subgroups and related apps to be ruled, this operation also led without any problem. From yesterday I found that something has changed, when I try to apply a new rule to an app a pop up ask me for “user confirmation……….”; also, and this is really strange and worrying, the insertion of a new app is not allowed (NIS firewall opens the window to make the app (.exe) choice, but then nothing is added to the subgroup). What has happened? I don’t think it’s virus related, after making a deep scan nothing suspect was found
