What is nwiz.exe?
Nwiz.exe is part of nVidia nView, which is typically installed along with nVidia graphics card drivers. It provides several additional features for users of nVidia video cards, such as the configuration of additional monitors and the expansion of the desktop to a size greater than the display resolution.

NView and the associated process are not essential to the proper operation of the system. Unless you are using the advanced features provided by nView, it can safely be disabled. If you are not using an nVidia card, but formerly were, you should remove nView to prevent a conflict. If you have this process but never had an nVidia card, it is possible that your system is infected with a virus or spyware.

Dangers of nwiz
As this is a common process on systems with an nVidia graphics card, it is common for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files will have the same name but will be stored somewhere other than in %SystemRoot%\System32 or %ProgramFiles%\Nvidia Corporation\nTune. Other malware will use a name that appears similar to it but with slight differences in spelling or with appended digits. The following malware is known to disguise itself as nwiz.exe:
  • Worm.Win32.Muma (also NWIZe.exe)
  • W32.Agobot.LQ/W32.Gaobot.ZX (%SystemRoot%)
    • This is a backdoor trojan that spreads to systems protected by weak passwords. It attempts to disable anti-virus and firewall utilities and maps the websites of most anti-virus vendors to the loopback address.
  • Troj/Dloadr-BLP
    • This is a downloader that downloads additional malware to %AllUsersProfile%\_qbothome.
  • Backdoor.Win32.Virkel.a
    • This is a worm that serves as a backdoor trojan, giving an attacker full control over the system.
There will typically be only one copy of this process running at a given time on a system. If multiple copies are running, one or more of the instances may be malware.

Common problems
  • "Nwiz.exe has encountered a problem and needs to close"
    • If this only happens occasionally, it is not cause for concern.
    • If the error occurs frequently, ensure that your video card driver is up to date. If it is, try reinstalling your driver and the nTune software
    • If the problem persists, and you do not need the features of nTune, disable nTune.
  • Graphical corruption
    • This can be caused by a faulty installation of the graphics card driver or the nTune software. Ensure that your driver is up to date and try reinstalling nTune.
