Looks strange :?
Cr4sh can you provide sample you used please? In my test RootRepeal2 detects TDL3.

Looks to me like it detects tdl3 - TermDD.sys
Yes, but I mean detection of infected driver (which contents are replacing by miniport hooks), during files scan.

Shure (only Dr.Web and remover from Norman detects this build).

I can confirm and back up cr4sh on this.

RR sees plenty of hidden code but nothing points to a driver or modified entry point.

%temp%\2.tmp is mentioned as a hidden module as well as a mysterious empty "hidden code". All others are IRP hidden codes.

Yes, I can confirm. Infected driver is atapi.sys, no proper detection.

I can confirm this, prior to reboot:
STEALTH CODE
-------------------
System 0x82ee28b4 - Hidden Code
System 0x82ee2ac8 - Hidden Code [Driver: , IRP: IRP_MJ_CLEANUP]
etc
Also with occasional reference to *.tmp

After reboot:
STEALTH CODE
-------------------
System 0x833028b4 - Hidden Code
System 0x83302ac8 - Hidden Code [Driver: , IRP: IRP_MJ_CLEANUP]
etc
System 0x83302ac8 - Hidden Code [Driver: , IRP: IRP_MJ_WRITE]
System 0xf762b8ad - Modified Entry Point [Driver: Disk, Other Val: 0xf762c514]

CALLBACKS
-------------------
LoadImage 0x8330496e <unknown>
In this case infected driver is Disk.sys, but no mention of miniport port disk driver being associated with irp redirection.

In case of detection after reboot - this is not RootRepeal2 bug. I think if you still interested you all should PM a_d_13.
