AntiVirus 2012 Update creates second update folder: can't merge or delete

I just updated my  AntiVirus from 2011 to 2012.  As with other products I was expecting that once the update was finished, it would delete the now unnecessary update files.  WRONG.  It did update the existing Update Folder in my Program Files Folder, but then when on to create a whole new folder with programs in "My Documents" section plus add an icon and shortcut to my desktop.  I can't delete the icon without deleting the folder and programs therein.  Nor can I combine the contents of both install folders.  What is going on?
