Hello. I had a quick question about Norton Anti-Virus 9.0. I purchased it about 2 weeks ago and installed it on my powerbook, but then I decided to sell that powerbook and got the new 15 Al powerbook. Can I install it on the new 15 Al or do I have to buy another retail version of Norton, which I don't mine doing. I did reinstall the OS on the old powerbook which deleted all my data and programs including Norton, which I did not register because I was in the process of thinking whether or not to get a 15 Al or not. Any help would be much appreciated. Thanks
