I was browsing last night and Opera suddenly stopped working. It looks OK, but wouldn't connect to websites via speed dial. When I manually typed in web addresses, it did not connect to them. When I did a Google search, a page of results came up but any links I clicked on did not open. So eventually I uninstalled and resinstalled Opera, and I still have the same problem.
I can get into my Gmail account through Opera, but not anything else. I can connect to any web page in Edge and Chrome, so the problem is not with the internet connection. I also disabled Extensions in case one of them was suddenly causing problems.
My computer runs Windows 10, and I use Kaspersky Internet Security.
I'd really appreciate some advice. Thanks
