its using a lot of processor but for what reason I don't know... sure I have SIS installed but nothing to do with my keyboard. stressedout
might have been nicer if they called the file "SiS-keyhook" oslt...
Probably SIS related, definately harmless Bruce
might be harm- (and use-)less, but older versions ar forcing some programs to crash (eg WordPerfect12 and QuattroPro12). Disabling and/or updating the SIS-driver solves the problem. Michael aus Deutschland

can be used to spy your keyboard but the original file used by Sis is not dangerous.

sis component, not needed much, safe to remove. Neil
Its a mainbord process but still it can be infected Martijn
Its totally safe. not a virus/spyware, mark
Keyhook.exe is used to allow multimedia keys on Acer multimedia keyboards to function correctly. If you stop this process all of the 'normal' keys on the keyboard should still function, but the multimedia keys will not. Only stop this process if it is causing instability to your system. Refer to the link. Hope this helps guys!  See also: Link eklegein

This program detects when you hit the shortcut keys on your keyboard. Not dangerous. may cause poor system performance. if you don't use the hotkeys on your keyboard regularly, i'd suggest removing it from your startup items. if you don't know how to do that, you can seriously screw your computer if you mess with those too much. Otter from Florida
i have an acer laptop with this display driver. one day, quickbooks started crashing. i found that if i stopped keyhook from running, no more quickbook problems. i think it's harmless, but obviously it can cause conflicts. harvey
Monitoring our network router - huge traffic load. Killing this server stopped traffic flow. Whatever it is, it's moving tons of data out to the Internet. Paul
reinstall your keyboard driver, you'll probably find the error warning go.
i though it was a key logger so i killed. but when i did my keyboard stoped working...can anyone explian that? SKY

caused "Multiview2000" to crash on acer laptop/disabling in msconfig fixed problem (fix was found while trial/error killing non-essensial tasks and retesting multiview, when i killed keyhook multiview began working instead of crashing at logon/diabled keyhook in msconfig and multiview hasn't crashed since) -i do note that the path in msconfig was c:\windows\system32\keyhook.exe - am unsure if this is correct loc for acer keyhook so i may have had a trojon(?) andygee51

does exactly what its sound like. its basically a driver and is used by lots of programs for keyboard shortcuts Luke Cann
Re-install Sis vga driver - works fine for me. Gus Hennings
Default when reloading Acer, but known issues with keyboard and mouse input. Locking up Acer Aspire 3000. Can be safely disabled and renamed in c:\windows\system32. After doing so, no issues are experienced in performance. TechJosh
Dangerous for online gamers (login information). Deleted once and some how it came a few houres later back. Fredosh
It's for Logitech Keyboards, it is safe. Disable it if you think it is causing you problems. or just disable it to test if your special keys on the keyboard work or not with it disabled.
It is a normal process but it can be reconfigured as a key logger. If it appears to be running for no reason, remove it.
Its harmless, the problem is its name is similar to something harmful (a keylogger). It comes from an older era thus the name is associated with modern spyware etc, thats the nature of that type of programming, they try to hide it as something you should have. SiS video drivers, Acer launch and keyboard hotkeys use the file name. I have all three of those, and have the error message at startup after trying to update the video driver direct from SiS website. "The file Keyhook.dll is not in the SysAp something or other".  See also: Link
