Temporarily Disabling McAfee Security Center 2007...?

McAfee 2006 had a function where you could right-click on the start menu icon and quit the program until you rebooted or enabled it again... but I can't find anything like that on the 2007. I'd like to be able to disable it for installing other things and my husband wants to disable it when he flies his Flight Sim programs... since he is not online when he does that, it's not needed.

Is there a quick way to disable McAfee Security Center 2007?

Thanx!
