Reset firewall to defaults not working

Hello Jane,
We regret to hear about the inconvenience caused to you. We would request you to run the AVG remover tool to remove AVG completely and re install it using offline installation file based on your OS ( 32 bit or 64 bit).
To run remover tool, please visit http://www.avg.com/tools#tba2 and click on "AVG Remover" to download the remover tool and run it on your PC. It will ask you to select which product you would like to uninstall. Please select "AVG Protection" and follow the setup instructions to uninstall AVG. Once the tool is run, your PC will automatically reboots. After the restart, please check if a folder with name AVG Remover is created under C:\ and remove it.

The instruction to "reset firewall to defaults" is not working, therefore I have no firewall protection!  How to fix?
