about one year ago i purchased a cd version of bitdefender v10 which supplies 2 users for 2 years each of antivirus and antispyware. i had kaspersky at the time (and still do), but the bd v10 deal was a good deal and found a way to fit it in the budget.
i installed one license on my sisters computer (it works great, by the way) approximately a year ago.
there is still an unused license. i still have kaspersky on my own computer for 2 more years, so i have no need for it. how long can i wait to take advantage of this unused license? thanks, Ed
