Easy way to turn Norton off?

Sorry for this very basic newbie quesiton, but I’ve just started using Norton Internet Security 2009.  Is there a quick way to turn it off, or is turning off each protection one by one (and then turning each one back on) the only way?  I’m thinking of a situaiton like when you’re installing a new program, and it’s suggested to turn off all other running programs during the installation.  Thanks for your patience,
