I am so sorry that your 30-days expired trial period Norton Anti-Virus has expired, therefore; you
CANNOT BE UPDATE when it already expired after 30-days trial period was over.
You
MUST HAVE TO purchase a renewal version yearly subscription of Norton Anti-Virus that will automatically replaced the 30-days expired trail period.
