Why does defender create service "MpKslfa1a362a" as a driver started at system start ? RRS feed

  • Question

  • Just refreshed pc with win 10, 

    Got process hacker running in the background popping up a notification each time a service is created or deleted. 

    And i saw this monstrosity : 

    binary path \??\C:\ProgramData\Microsoft\Windows Defender\Definition Updates\{686BE312-53BF-42D7-BD22-F978B5019D6D}\MpKslfa1a362a.sys

    appears to have randomly generated name but the sys is the same. 
    What purpose does it serve ? Why is it obfuscated to such a degree that it screams malware everytime you look at it ?
