My netbook has Norton Int Protection and it's time to renew. itcosts $50 to renew that subscription. But for $60 we can get Norton 360 for three computers, although this is on CDs compared to a download for the renewal. T will be geting a new computer soon. When going to checkout, they are suggesting we get their download insurance for $7. That doesn't make sense to me if we are buying CDs. If we get the 360 is there any time limit for installing it on the 3 computers? Am I missing something? Seems deceitful to sell download insurance when you're not downloading anything. Anybody know about this?
