IRP_MJ_SCSI kernel mode hook on mvs91xx.sys - What is this and is this bad? How to prevent this?

[Tempnexus]

HitmanPro with EWS is showing this alert:
IRP_MJ_SCSI kernel mode hook on mvs91xx.sys detected and bypassed.
The device stack the hard disk is referencing a hidden driver. This could affect the detection of malicious files.

What is this and is this bad? How to prevent this?

Picture is worth a 1000 words.

Are you running HitmanPro.Alert 3.5 (or newer) as well? Then this is most likely the WipeGuard kernel-mode hook of HitmanPro.Alert. You can see in the log file where the detour points to.

WipeGuard protects critical boot sectors of the system. Its current implementation is a bit limited but it will gain more features in upcoming builds.

NOTE: This detection is only shown if you run in EWS.
