The nod32kui.exe process is associated with the Nod32 Antivirus from ESET. This process should not be removed to ensure that your system is secure. ESET only announces its presence when there's something newsworthy, like the interception of a virus in a user download.

Most of the time, the file nod32kui.exe runs silently. By default, the virus signature database updates itself quietly in the background without user prompting. The program's tray icon can pop up a notification balloon to tell you that a new set of definitions or program updates have been applied. Scans initiated from a right-click context menu can be run in the foreground or sent to the system tray to run silently in the background.

Known file sizes on Windows XP are 917504 bytes (40% of all occurrence), 921600 bytes, 950664 bytes, 949376 bytes, 851968 bytes, 778240 bytes, 782336 bytes, 847872 bytes, 28672 bytes and 103424 bytes.

The program uses ports to connect to LAN or Internet. The nod32kui.exe process is able to record inputs, hide itself, and monitor applications.

The application nod32kui.exe control center is a system tray app for the NOD32 antivirus program, which appears as a CC icon in the System Tray. Double-clicking on the icon enables you to configure NOD32 or to manually update it. The Control Center is also responsible for automatically downloading updates to NOD32 if you have configured NOD32 for automatic updating.


This is a safe process. There is no necessity to remove this process from your system or change it in any way.
