Hi Guys,
Norton Anti-Virus and Firewall from BT Yahoo! is being replaced by BT NetProtect Plus. If you're a BT Total Broadband Option 2 or 3 customer and you're using Norton, you must download the new service now.
If you don't download it by 30th June when the service stops, your PC will be left unprotected from online viruses and other threats.
See here:

Hope this helps.
