I use BT Broadband Option 3. After dowloading the software from the BT Yahoo software centre . have had countless problems, ultimatley resulting in the loss of my network connection. Fortunately my system restore point resolved the problem, however I cannot download BT Broadband online help, or norton utilities without the same problem occuring. Despite having forced the removal of all the Norton antivirus utilities (which download did not complete properly), the computer still seems to think they are there and that seems part of the problem. The desktop help function results in an error message and subsequent loss of connection. In fact the only software I can download without problems is the browser. BTs useless technicians have been unable to help, and although I feel this problem may not be resolved I was wondering if anyone had any ideas.
