I've been using Norton products since 1999 and have decided to not renew. Each version brings new problems, too many to list here. The last issue is I can no longer use Norton Antivirus with Outlook 2010. With the Norton add-In enabled not only is Outlook excessively slow (launch - very SLOW, send, receive) but it resets all my Outlook categories to the 6 default Outlook color categories (all my custom categories are gone). This impacts everything I do, all my categorized emails, tasks, contacts and calendar items.
