If I buy Norton 360 today, but do not activate it until a year from now, will the software and my subscription work normally for one year from the day of activation?

Normally, activation keys do not expire, therefore, if you purchased your Norton 360 subscription from a trusted source, you should have no trouble using activation key a year down the road. We say “trusted source” as there are cases when a great price is offered, but activation keys are either invalid or don’t last for time claimed in the offer. We always recommend Norton online store as a first choice. Certainly, retailers like Staples, Wal-Mart, Best Buy and similar are trusted, too.
