Controlling updates

I apologize if this has been answered before.  I did a search of the boards and couldn't find an answer there.

 

In the past, there was an option to control when automatic updates downloaded and were installed.  I remember distinctly, because I used to have it set for 3AM every night, and I had to change that to 6AM because I started working 3rd shift at my job.

 

Where has that option gone?  I cannot find it anywhere and I am SO tired of Symantec hogging all of my resources in the middle of a project.  If it is really gone, I do not think I will continue my membership - it has become that frustrating for me.
