The genuine mfehidk.sys file is a software component of SYSCORE by McAfee LLC.
"Mfehidk.sys" is the Host Intrusion Detection Link of SYSCORE, common to all McAfee For Enterprise cybersecurity products, (which ePolicy Orchestrator can manage remotely), including VirusScan Enterprise. It installs in "C:\Windows\System32\drivers". It is a "kernel mode" and not a "user mode" driver. When multiple products using SYSCORE are installed, this driver's version is the installed SYSCORE version level. The Validation Trust Protection Service (mfevtps.exe), without which no McAfee process loads or runs, to prevent intrusion by falsely-named malware, depends upon this driver. Under Win7 or earlier it is the first SYSCORE driver to start when Windows does; under Win8 and later, the Microsoft ELAM (Early Launch Anti-Malware) Framework first starts "mfeelamk.sys". Consult network administration before trying to stop or uninstall SYSCORE software. Certain key McAfee processes automatically restart because malware tries to kill them. McAfee LLC is the world's largest dedicated security technology company.
