This was really driving me nuts. For weeks now, Norton Antivirus 2000 for Windows NT has been bugging me that my subscription is about to expire. However, when I clicked the clickables, the only option it gave was to phone a number; a number that is apparently always busy.
There used to be a way to do this over the Internet! Symantec's Web site wasn't of much help; in addition to providing two more useless phone numbers, it told me that I should upgrade all software components, something I've done already.
At long last, I found it. In the Registry, find the key HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Norton AntiVirus\DefAnnuity. Under this key, locate the DWORD value InternetEnable. If this value is zero, set it to 1.
I should hasten to add that despite this minor inconvenience, Norton Antivirus and its $9.95/year subscription is one of the best ways money can be spent...
