This problem arrived a few weeks ago: prior to that everything had been working fine for 2-3 years. Now Chrome refuses to connect to the internet, and Google Earth won’t run because it can’t connect to the server. Firefox runs fine, though, as does my email and other browsers. Having tried a number of things (virus scans and checking firewall permissions etc.) I closed Kaspersky Total Security, going back to Windows Firewall. And everything worked. So the problem is caused by Kaspersky. I can manage without it - I have alternative anti-virus I can use, for instance - but I have a good while paid on my subscription so I would prefer to use it. if anyone has a helpful suggestion, I would be grateful. Oh, and I have also tried uninstalling and reinstalling both apps, which didn’t help. As I say, Kaspersky is the problem. i run the latest version of Windows 10 Home.
