On one of my PCs when signing on to my account via Internet Explorer 10 / Windows 8.0 I get a message saying my browser is out of date (sometime it implies I am running Internet Explorer 7.0). It used to be OK but it isn't now; it is OK on Firefox on my PC, Internet Explorer 10 on another PC and my Android tablet. I can go into login.norton.com, sign-on, and that is OK and choosing 3 of the menu options is OK but if I choose 'My Norton' it goes to manage,norton.com and then I get the out of date message via manage.norton.com/Error/UnsupportedBrowser. Both Microsoft and Norton claim it is not their problem. Attached is the web page source (with some personal data changed) Any ideas? Thanks in advance, Pete.
