Calling up Norton desktop

I recently bot a new computer and moved from Windows XP to W7 and have Norton Internet Security running.  I now want to change some settings in it, but for the life of me can't find the exicutable file to do that. 

 

I have found   Program Files (x86)\Sumantec, and searched for all executables w/in it to no avail.  I've gone to start/All Programs and searched for both Symantec and Nortion, but I didn't find anything that worked for me.  I've even gone to the Windows control panel / Programs folder for a list of programs to uninstall or change.  That didn't give me any clue.  Sorry for sounding so dumb, but I don't know what file or shortcut I want, and W7 doesn't list all the executables to pick from.  So please help.
