Your connection is not private

Alan,
I understand this must be annoying, let’s try to fix it together.
I suggest you to change the firewall network profile from "Public" to "Private" and check if that fixes the issue. To change this settings, please open the AVG Internet Security and click on Menu>Settings>Components>Firewall>Customize>Network profile.

Also, please Enable all the System Rules under Menu>Settings>Components>Firewall>Customize>Policies.

In case issue persists, please provide me a screenshot of the error message. Here is a link with the steps to create a screenshot: http://avgclick.me/getscreenshot . You can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.

Hello!
My computer is running Windows 10. I have installed and am using Avg Antivirus. When you trying to open some websites (youtube, facebook…) they won't load and I am facing the error as below:

Your connection is not private

Attackers might be trying to steal your information from www.youtube.com (for example, passwords, messages, bank information or credit cards).

NET::ERR_CERT_DATE_INVALID


Some my friends suggest me uninstall AVG and then the error is gone.Anyone has the same problem ?

Your internet security blocked SSL connections, and there is nowhere to turn off “SSL Scanning” feature, you can try to disable the program temporarily to check.
You can open the webpage in Incognito mode. If the webpage works, a Chrome extension is causing the error.
