The Norton Firewall is causing issues with paying online, as it is blocking the two step verification process used by Mastercard, without issuing the usual 'do you want to enable this' pop-up.
My son who is an experienced computer scientist could not work out how to stop this happening. He suggested using windows Firewall and Norton for the rest, but Norton disallows this configuration. So the only option is to uninstall Norton. We could not find the right page in the Norton online help, either.
In any case, it has massively affected the performance of the laptop.
If you have any direct links to the correct information I'll gladly give it another go.
Thanks
