This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
Your best bet is to pop them a quick query here: http://www.eset.com/us/company/contact
It should be fine, as it is time based, but they'll be able to give you a definitive answer.
