SiS Compatible Super VGA Keyboard Daemon Languege = chinese (Taiwan)
It's Used in Notebook, it work for Displaying Icon on Screed, like OSD, for Advanced function of laptop
Used in notebook computers for things like TV-Out enable hotkey
something related with SiS, but it wastes memory
Not really needed, but downgraded performance considerably. Many programs take on this name and HOLY HELL can they cause trouble. Most problematic for the DOS base
appears to slow the PC down

I just did a clean install of Win XP Pro on an MPC Laptop... khooker showed up right after I installed the motherboard drivers.
controls externals on laptops, e.g. touchpad, graphics card, etc from SiS. Sometime freezes up if the registry has some damage.

Best practices for resolving khooker issues

A clean and tidy computer is the key requirement for avoiding problems with khooker. 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.

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