Comcast allows norton on 7 devices. I can not add a new computer because I have supposedly maxed out, but I don't even have 7 devices. I suspect the 7 devices include some I haven't had for years. Can I call up a list and remove these?
A list of your devices should appear when you attempt to insatll the 8th device and ask you to delete one of the old ones in order to add the new device.
Ensure you re loggd into Comcst as the Primary user, and working from your residential modum.
