The genuine atchk.exe file is a software component of Intel® Active Management Technology by Intel Corporation.
"Atchk.exe" tells the user if their computer has Intel® Active Management Technology (AMT) installed and whether it is active, using a Privacy Notification Window at startup, (or when the user changes), and a system tray privacy icon opening a dialog box with a hyperlink to a website about AMT. In level 7 of AMT (and later), it is replaced by "UNS.exe." The "C:\Program Files\Intel\AMT" subfolder where "atchk.exe" resides should have an executable "disable.reg" file that changes registry settings to prevent its starting up. AMT is part of Intel® vPro Technology, an enterprise security solution where desktops, servers, ultrabooks, tablets and laptops have the Intel® Management Engine built in, with AMT designed into a secondary processor on the motherboard, intended for use with software management applications to enhance system administrator ability to remotely access even computers that are not powered on. Intel Corporation is the world's largest and highest-valued semiconductor manufacturer.
