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
