Can't connect to websites

Thank you for trying to help me to resolve my issue. I still can not access any websites, the message I got are "This site can't provide a secure connection", "Connection was re-set". I have tried your suggestions as follows:
1) turn off AVG internet security : after I restarted my computer, the protection is back on, then same issues occurred.
2) try change my VPN location to Gotham City, the same problem still exist.

Please advise next steps or other solutions. Thanks
