I read the minimum requirements of Norton AV 2009 upgrade, and they don't require an existent license/subscription.
So, if i Buy the upgrade Box of Norton AV 2009, I am able to activate my trial version installed on my computer?
Because usually I don´t pay for software, I use always freeware, and is the first time that I go to pay for any kind of software, and the upgrade version (on my local store, not online) it's ~10€ less (34,90€ vs. 44€).
