Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I can provide advice about Norton Internet Security, and its reinstallation or renewal.
Renewing a subscription with Norton or Symantec with regard to their software, is best done through that same software.
Check your subscription status using the software (you must be online at the time, and have internet access.)
Then if prompted that your subscription status is 'expired' or similarly, go to the link to Renew.
At what point in that simple chain of procedure, does the procedure break down? I will help you through it.
