I am presently using a Norton three user license that will expire in March of 2012. If I purchased a new CD via newegg.com which qualifies for a Norton $35 rebate, but don't install the new product until March 2012, would the license be good for 12 months. Or, if I run the CD, would 12 months be added to my active subscription? I'm sure if it would be it would also upgrade to A-V 2012. Thank you!
