It may also be used by the Screensaver component of Windows, to measure the duration of a period of non-use of a machine so that the Screensaver may be set off. It may also be involved in power-saving, because, when the clock is ticking towards power saving, keyboard activity is one factor in preventing that power-reduction.
Its calling SetWindowsHookEx(). It's a system hook DLL that is used to intercept mouse and keyboard events. Its apparently checking for user activity to update Yahoo Messenger status.

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.
