Title
Early Launch Antimalware, Boot-Start Driver Initialization Policy must prevent boot drivers. (Cat II impact)
Discussion
The default behavior is for Early Launch Antimalware - Boot-Start Driver Initialization policy is to enforce "Good, unknown and bad but critical" (preventing "bad"). By being launched first by the kernel, ELAM ( Early Launch Antimalware) is ensured to be launched before any third-party software, and is therefore able to detect malware in the boot process and prevent it from initializing.
