You should be able to find your Wi-Fi access point and it should say it is secured with WPA or higher or be listed as unsecured (wide-open). One way to detect what type of Wi-Fi access you have is to right-click the Windows Network icon in your system tray.Seems that is the way they set up their consumer routers. Here in the USA, Xfinity Wi-Fi routers (also Comcast) are set up as wireless hotspots where anyone can connect to that access point without a password, much as you can see from where you are. Wi-Fi access is controlled by the router, and not the Avast Firewall.
