Windows 10 browsers are not connecting to internet but any else is...

So Im using my mobile data on my pc with usb modem ofc and so now randomly (couldv been after update) chrome or any other browser doesnt take internet connection, youtube page worked in chrome buy anything else no. Other apps like steam works well with net and even games do so it shouldnt be internet problem. Whenever I launched a new tab (witch/twitter/fb or whatever page) then it said err_connection_closed or later with on err_timed_out, looked up for some help on yt, did the cmd stuff with ip reset and flush and other things there were said, cleared out chromes data but still nothing, uninstalled chrome then tried to install it back from Edge or explorer but ofcourse nothing worked, Edge said page is not safe or something.. Tried safe mode but what else to do there if no connection and theres no option to make safe mode with connection... also same with me sharing net to pc (like wifi).. need help, soo frustrated already.

Welcome to the forum check all browsers sent set to use a proxy. Open a CMD prompt type

What do I write to CMD prompt? Still no idea whay proxy is tho

Yes you open a. CMD window then type the CMD. Normally you connect direct to the net but with a proxy you don't you connect to a server that supplies the net often there set wrong or some anti virus run one but if you remove it then the server isn't there. You got to browser Network setting and make sure you don't have one set as this will stop all internet

If I write CMD in cmd prompt then it says "Microsoft Windows [Version 10.0.17134.345]

And Im not connected to a proxy server, it is on "Automatically detect settings"
Also I have free Avg antivirus and also free Avast.

Nevermind this all. The main problem was AVG antivirus... somehow or somewhy it blocked every browsers connection to the internet connection but still allowed steam or other apps or games to work.
