Today a new issue happened with all my browsers (Chrome, Edge and Firefox)
When I try to launch a browser and go online, all the pages don't load. All I have is a message saying that the website (ex: youtube.com) is temporary unaccessible or was moved permanently. ERR_HTTP2_PROTOCOL_ERROR
When I start another program like steam, it's able to connect to the internet. Same with the windows 10 update center.
When I deactivate Kaspersky Internet Security app, all my browsers behave normally. It's only when I reactivate it that I lose my connection to most website I use.
Eveything was fine for the past year so I don't understand what happened?
Thx for your help!

Thank you for your help guys.
Finally I had to reinstall Kaspersky and all the issues I had have been fixed.
