How to Turn Off Norton Alerts

Instead of putting my Norton AntiVirus into "Silent Mode" all the time, I would instead like to know how to possibly disable Norton Performance Alerts and System Check alerts.

 

I can't seem to turn off Performance Alerts nomatter what settings I change, and I'll always get "updates" about "updater.exe" has been patched successfully or whatnot.

 

How do I turn all of these off?
