Can't access internet with Chrome, Firefox after Win 10 upgrade, Edge works fine though

Posted

Hi,


I just upgraded my mom's PC to Windows 10. Everything went well but after the upgrade only Windows Apps such as Edge can access the Internet, nor Chrome, Firefox or Avast can access the Internet.


I've of course checked Windows firewall, but everythings looks fine.


Please, help me - what shall I do?


Thanks in advance.
