While I appreciate Avast! switching security settings as I move from one network to another, I think it's annoying to be told this when switching among known networks. Twice a day, as I move between home and work, I receive a popup stating that change. I can see a rationale for prompting me when I encounter new networks but not for known networks.
I tried turning off in the settings/popup menu to no avail. I have 0 seconds for Info & Update popups & 5 sec. for Warning & Alert popups.
