You have been attach aswMBR.txt logreport, not MBR.dat file.

Please re-try upload that file to me again? I need to examine that file becouse your MBR might be new kind of malware.

When you upload MBR.dat and post here download link, then just re-run Combofix. If CF wants to be updated or to install Recovery Console, allow it.
