Regarding NVidia drivers I allways disable KIS when I install them.
I had never any kind of popups from NVidia.
But that's the sensible way of doing things:-if you're installing anything on your PC,as long as you know what it is ,want it and know its "clean" you should always disable any ant-virus software you're using,if I remember correctly from when I had a nvidia card its even in their installation instructions
This is from nvidia website:-
Driver Installation Hints
•"Download Accelerator" utilities should be disabled when downloading any drivers.
•Do not run virus protection software in the background while installing the drivers. This prevents the driver from configuring itself properly.
