I tried to log on to the mail server through the talktalk web site and got a similar message in the firefox browser. The same thing happened to me a while back with the natwest web site, AVG investigated and could not find an answer. natwest checked their site was secure. Firefox says it's a problem with the web site. where do I go from here?
