I received an email telling me that there was a glitch with Norton Systemworks in calculating the amount of time left on it and my current subscription would be extended a year. I am currently using Norton Internet Security 2009 and my account shows it expiring on Dec. 8th, 2011 but NIS 2009 has not yet been updated to reflect this. I have 48 days left on my current sub to NIS 2009. Will it update to the 2011 date or do I have to actually renew my subscription?
