A:Answer I believe so, just try to find an expiration date in the packaging. If there isn't one, then you should be able to activate it whenever you want. I do know that if you already have AVG installed on your computer, then this will override your other subscription. They don't stack on top of each other. I lost the 70 days I had left when I installed the new subscription. Called AVG customer service and confirmed that was the correct result. Bummer. I still love AVG though and will continue to use it.
