Loaded with new labtec keyboard. I suspect the key capture is to enable the programmable soft keys supported by the keyboard

kbhook.dll is a file installed if using a wireless keyboard!
It seems that it loaded when i install de drivers for my wireless multimedia keyboard and mouse from genius
it also loaded when I installed my new Genius mouse NetScroll+ Superior with cord. When I run anti Spyware they tell me it is dangerous. When I remove it my Mouse cannot do its special features. I don't know what to do.
Will not cause any harm. As said abvoe, it is used for the 'Genius Wireless Keyboard'.
It is used by Genius Wireless Optical Office devices.

Right. It is used e.g. by Genius Wireless Keyboard Drivers for the Hotbuttons. MS AntiSpyware false detection, XoftSpy false detection. BUT NETSPY ALSO USES A KBHOOK.DLL! anyway it differs from the one distributed with keyboard driver package

Assuming you have installed a wirleess keyboard or mouse, Dont worry.
Correction kbhook.dll is a malware form. kbdhook.dll is associated to likes of logitech for wireless or express button functions
It is absolutely needed for the Genius Wireless Optical Mouse, without it just doesn't work properly. It would be nice if someone at Genius could verify its authenticity, or even get it digitally signed.
There are many programs that use it, but for me, it is the keylogger part of "GoldenEye", a program i installed on my own pc to check if my sister had been on it or not... it works.

I don't have a wireless keyboard (I do think it came with my new keyboard though, a Genious)
This is an essential part of my labtec keyboard software, and is not dangerous
genius Maustreiber
suspicious about it because it's not labeled, has no name to it
It was installed with my Genius ErgoMedia 700 keyboard (USB). It is used to map the various additional function keys on the keyboard.
  Marvin   (further information)
suddenly after a while my virusprogram (trend micro) find the "TROJ Generic" Virus in it.. It should be dangerous
It is also used by goldeneye (keylogger program)
Is an aditional .dll für Genius wireless Keyboard and Mouse
It installed in c:\windows\system32\ at the date i added labtec wired keyboard
"My" kbhook.dll placed in c:\windows\system32 is nothing more than file created after installing drivers for Genius (not wireless) keyboard.
I also have genius keyboard, but not wireless. I found two files with the same name. One in system32 directory, second in mediakey directory. The first one was marked as keylogger by antivirus. Deleted it, pc still works.

Best practices for resolving kbhook issues

A clean and tidy computer is the key requirement for avoiding problems with kbhook. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
