Blocking all content from certain TLDs
I've just had an issue where I nearly clicked through to a website based in Russia, masquerading as the Birmingham Post. It was an exact replica, and only because I spotted the website was actually .CO.UK.RU I didn't click through.
It made me think - is there a way to block access to certain TLDs/country codes? I doubt that I'll ever want to access a Russian website, so I'd like F-Secure SAFE to warn me if I go to such a website.
I can't find an obvious way to do this. Is it possible?
