I am flying to visit my elderly sister tomorrow, and I have just been advised that she needs new/upgraded AV protection. She had NIS 2009, but the subscription was not renewed, and I don't know how long ago that occurred. I do know how to recover her product key (her NIS disk can't be found). What is the best and fastest path to getting her running with the current product? Do I need to remove NIS 2009 first? Would downloading NIS 2010 be superior to purchasing a new boxed edition? I want to help her, but I don't want to spend any unnecessary time doing computer maintenance.
Thank you for any help!
