I purchased Norton Internet Security 2007 It is current. The license (protection) I got with it is for up to 3 PCs. I now have a netbook. I want to put the Norton I have on it. My subscription for this is still good for over 500 days. Am I going to have to pay for this one or is this one covered with the subscription I have? Hope someone understands this. Also, If I can use the one I have, The netbook already has Norton 2003 on it bit it is expired. Will the NIS2007 write over the older version or remove it when the newer version is being installed?
