What is ps2.exe?
This is part of the HP keyboard and mouse drivers. Its purpose is to facilitate the configuration and functionality of the special media keys on some HP keyboards. It came preinstalled on older HP desktops with a PS/2 multimedia keyboard or mouse.

This process is not essential to the operation of the system; however, it should not be removed unless it is causing problems. Removing or disabling this program may prevent you from being able to make use of some or all of the media keys on your HP keyboard.

Dangers of ps2
As this is a legitimate executable that is installed on many systems with an HP keyboard, it is possible for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name as this process but be stored somewhere other than in %SystemRoot%\System32. Other malware may use a name that appears similar to that of the legitimate one but with slight differences in spelling or with appended digits. The following malware is known to disguise itself as ps2.exe:
  • W32/Duload-A (%SystemRoot%\media)
    • This is a Trojan that spreads via the KaZaA network and changes infected computers' default shared KaZaA folders to %SystemRoot%\media.
There is typically only one instance of ps2.exe running at a given time on a system. The presence of multiple instances may be an indicator of a malware infection. If you do not have an older HP keyboard or mouse, the presence of this executable is a likely sign of a virus infection.

Common problems
  • This program generates an error upon shutting down the system
    • This is a known problem. Try reinstalling your keyboard drivers. If a simple reinstall does not work, download the latest drivers from HP's website. If that still does not work, you can uninstall the software. Note that this will disable some of your media keys.
  • Ps2.exe freezes on startup
    • This is a known problem under Windows XP Service Pack 2. Try downloading the latest drivers from HP's website. Alternatively, uninstall Service Pack 2, install the driver, and then reinstall Service Pack 2.
