Verified Purchase(What is this?)
This review is from: Norton Internet Security 21.0 - 3 Computers, 1 Year Subscription (PC) [2014 Edition] (DVD-ROM)
I put the disc in and worked and not only that but it added all my days on to the 365 so I had 376. I've used Norton internet security for 5 years now and it gets better every year.
