I dont like the security center myself. Which is why I disable it.
If you would like to do this then,
right click on my computer
select manage
A window called computer management will pop up.
Expand the "Services and applications" icon by clicking on the +
Now select "services"
In the right column Scroll down to security center,
right click on it
select properties
and select startup type > Disabled
close everything , and restart PC.
