last week i had a problem with the firewall allowing avast installer to access the internet and i was getting this pop up 8 to 10 times a day any way i uninstalled the firewall the reinstalled it and that problem has stopped but now when i start the computer i have no internet if i run a diagnostic scan its says security or firewall may be stopping it so if i disable avast shields the internet come back on i the reinstate avast then everything is as normal
This may help. Check your Firewall Settings.
Make sure the Firewall “Profile” is set to Private, not Public.
profile is set to private
