Can't connect to websites

Thank you for your prompt reply. I disabled the AVG Internet Security, and I was able to access all sites. Once I restarted my PC, with the protection back on, then the same issue occured. 
What should be my next steps? Thanks.

Thank you for replying back to us, Sophie.
We appreciate your efforts in resolving this issue.
Now please try to change AVG Secure VPN server location to Gotham City or Wonderland and then check if it helps.
Also please mention the version of AVG Internet Security program being installed on your computer.
(Open AVG Internet Security – Menu – About).
