Creative Technology sound card driver (?)
Came with creative nomad mp3 player
This driver of Creative Audigy 2 sound cards is not dangerous but the cause of a tiresome system error (see Link)
  JGWB   (further information)
Should be in %SYSTEMROOT%\system32\drivers - Part of Creative Sound card drivers
  Curio   (further information)
Maybe from MP3 player? I did have a Nomad installed on this PC, but this file didn't go away when I uninstalled the driver.

I think I got it when I installed the Creative drivers and soft for the Creative Zen mp3 player.
Possibly came as part of Creative WebCam package, it appears to be not functional although the webcam package works perfectly. It (pfModnt) generates faults in the system log tough.

En Windows XP SP2, Es un Archivo de Sistema que se ejecuta a nivel de la ROOT (Raiz) y corresponde a los controladores que no son Plug and Play, ademas puede ser deshabilitado desde el Panel de Control.

Installed as part of the full software package shipped with Creative Labs Audigy sound cards. If Creative hardware and apps are removed, there may be orphaned registry keys causing errors -- and random, intermittent lock-ups -- when Windows tries to start the associated service and the file is no longer in the Windows/System32/drivers directory. Usually deleting the registry keys containing PfModNT.sys resolves the error.

Best practices for resolving PfModNT issues

A clean and tidy computer is the key requirement for avoiding problems with PfModNT. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the PfModNT.sys process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
