Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. You should be able to use the new password ***** got from resetting on all the devices connected to this Norton account. As for Avast what happens when you try to uninstall it? What happens when you try to use Norton? Why are you using Norton rather than Avast or Microsoft Security Essentials?
