Monique, Please check if AVG firewall is configured with below recommended settings or not.
Open AVG Internet Security->Menu->Settings->Components->Firewall->Customize->Network Profile and change it to Private. Open AVG Internet Security->Menu->Settings->Components->Firewall->Customize->Policies->System Rules and set all rules to "Enabled".
Make sure the above settings are applied and let us know if the issue persist.
