I am facing the same issue. I have re-installed Windows 10 afresh and all Drivers and the system works fine. AVG Free installed. Many websites I used to browse earlier are now blocked by AVG. All broswers like Chrome, Firefox and Edge are throwing out THIS SITE CANNOT BE REACHED. Internet is fully connected and only some sites are opening. AVG;s own support site is being blocked by AVG Free. I understand paid version users also face the same issue. AVG Tech team, who made this possible with the new program update are simply playing spoilsport and giving irresponsible answers which in no way will resolve the issue. There is no way to disable Anti Tracking in AVG Free as claimed by many AVG Tech Team members, who have deliberately created the site blocking issue to drive away AVG users from using their product. They ask for this and that and they are fully aware that they are the creators of this issue and deliberately, they are playing hide and seek by suggesting irresponsible answers to resolve the issue just to cause irritation to AVG users. Uninstalling AVG resolves the issue completely and then only I understood that AVG was the sole culprit behind THIS SITE CANNOT BE REACHED error. They know what needs to be done and that is, identify the person or team who deliberately created this issue for all AVG users and fire them out of the company and make alterlations in the program NOT TO BLOCK any websites. While AVG's own support site is getting blocked by AVG, one can imagin the frustration, angst and irritation it creates for the users. AVG Chief should immediately interfere and give an ultimatum to the team who deliberatley created this issue and STOP pretending that you are not aware of this issue so far. AVG team is fully aware of this issue and if they again and again play hide and seek and keep on suggesting irrelevant and irresponsible answers to users instead of resolving the issue thru a program update, they will sure pay the price of AVG being rejected by most users. DO NOT PLAY SMART BY PRETENDING THAT YOU ARE NOT AWARE OF THE ISSUES. YOU ARE WELL AWARE OF THE ISSUES FACED BY USERS AND YOU ARE SIMPLY ENJOYING THE SUFFERING BY THE USERS. You may stop pretending ignorance and do the needful urgently to resolve the issue.
