The genuine i8042prt.sys file is a software component of i8042 Keyboard and PS/2 Mouse Port Driver by .
Microsoft Corporation’s «i8042prt.sys» process is a driver for one specific hardware device, the i8042 keyboard and auxiliary device controller which handles both the PS/2 port for the keyboard and the PS/2 port for the mouse. Its proper location is «C:WindowsSystem32drivers.» Anywhere else this name is probably disguised malware. PS/2 ports were introduced in 1987 and are still sometimes preferred over USB for the keyboard and mouse. Large enterprises, for example, can obstruct data theft or malware introduction by having no USB ports where thumb drives could be inserted. Note that if a USB keyboard is added to a PC that has PS/2 ports, this forcibly disables «i8042prt.sys» and the PS/2 keyboard no longer works except by manually changing a registry value. Microsoft was founded in 1975 by Paul Allen and Bill Gates and is today a highly-valued multinational hardware and software technology company.
