Nod32krn.exe is the kernel service, nod32kui.exe is the user interface.

If kui is just the interface, then how come when you quit the control panel the kernel is still running?

Not sure what you are asking here, but it would make no sense if closing the GUI should stop the kernel service. Also when you quit the GUI what actually happen is that it's minized to systray so it's not actually closed. That's why nod32kui.exe is still running after you quit the GUI.

The "Hide" option is what minimizes it to the system tray; and when I quit it I get the following message:

Quitting the program will disable virus warning. Do you want to quit the program anyway?

Quitting the program will disable virus warning.

That simply means you will not get the big red warning screen. nod32krn.exe is still running and will continue to stop any malware.

Does quitting the control panel serve any purpose?

Not as far as I'm concerned. It may release some memory but not much.

Take a look at the help file and see if it clears some things up in your mind.

The NOD32 Control Center is the central management program of the NOD32 antivirus system. The system consists of the following threat protection modules:

AMON – the resident (running in operating memory at all times) or file system monitor. This program is the most crucial antivirus defense tool and should always be enabled.
NOD32 – (also referred to as the "on-demand" scanner) this is the scanner executed manually by the user, or automatically by the scheduler.
IMON (Internet MONitor) - this scanner provides the first line of defense by monitoring Internet traffic (POP3 protocol for e-mail and HTTP for files downloaded from the Internet via HTTP)
DMON (Document MONitor) - this scanner provides protection from macro viruses in MS Office documments, works with applications utilizing MS Antivirus API (e.g. MS Office 2000 and higher, Internet Explorer 5.0 and higher)
EMON (Email MONitor) – this scanner provides protection from email-borne viruses for MAPI compatible mail clients
The other Control Center sections are:

Update – this program provides automatic Internet/network update of key system elements including the executables and virus signature databases (a valid username & password is required).
Logs – a management tool for maintaining the system, virus alert, and on-demand scanner logs.
NOD32 System Tools – includes a variety of tools making the use of the NOD32 Antivirus System's user-friendly and powerful features. Includes Quarantine, Scheduler/Planner, Information, and System Setup.
