Help,

Why suddenly I don’t have internet connection using Chrome and IE?

We will need more information to help fully.

What avast version do you have avast free/pro/ais/premier and what version is it (12.3.2280 is the latest) ?
What is your operating system and firewall?
Are you getting any errors displayed to the screen ?

Has anything changed on your system around this time that you lost the internet connection ?
