How to turn off KDE4 Software Updater?

In my OS 13.2 with KDE4 desktop, the KDE Software Updater keeps bugging me to install updates, competing with YaST. How can I turn it off? I’d prefer that YaST handle my updates.

de-install the package ‘apper’ with yast

Step 1: Configure Desktop → Startup and Shutdown → Service Manager
Then uncheck the box for “Apper monitor”

Step2: Right click on tray, and select “System Tray settings”
Then uncheck the box for Software Update. (You might need to first unlock widgets).

I’ll give this a try.
