Upgraded Microsoft Office from 2007 to version 2010 32bit. NIS 2010 Anti-Spam works, however, no AntiVirus shows as installed in Outlook 2010 settings. Worked correctly with previous Office Outlook 2007, while running same Win7 32bit operating system. Have turned off Norton Email functions in NIS 2010, restarted system, turned features back on and still not integrating with Outlook 2010. Very important to know that I am properly protected with email! Contacted Norton support via chat, who advised me that "that feature is unavailable with NIS 2010". I have been using Norton products for many years and find that hard to believe as Norton has always been in the lead on their software. I purposely waited to upgrade Office 2010, to allow software companies to design their software accordingly.
