Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Before this happened, or even when Norton said your account was blocked, did you receive an email asking you to change your password ***** enter a new password?
Or, did the Norton block page have you change your password ***** enter a new password?
( if you havent done so, do not try to change your password ***** )
Also, what browser are you using, firefox, internet explorer, google chrome?
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
