I accidently deleted the antivirus software when i tried to clean up my hard drive. I have the product key and serial number of the Norton Antivirus, but can't find the link to download the software for mac. All the links direct me to the download for windows. I've spent two hours poking through the norton website and waiting to get connected with a customer support rep with no help at all. I have to say Norton has the worst customer support. Can anyone help? Many Thanks!
