Well I would say you have nothing to worry about as what is being detected is the data file created by the aswMBR.exe scan, it produces the mbr.dat file (which is effectively a copy of the MBR) and when you save the scan the aswMBR.txt file.
So because the mbr.dat is a copy of the MBR and in this case since it is a non-standard MBR avast is having a bit of a fit on it.
Now that it is in the chest it shouldn’t be an issue, though having recently run aswMBR.exe again there would be another copy of the mbr.dat file, so be aware of that. Now that we have determined why it is an unknown mbr code you can actually delete any mbr.dat file on your desktop or C:\Users\Admin\Documents, etc.

Looking back on your log and the location this was found, C:\Users\Admin\Documents it means you ran the aswMBR.exe as Admin.
So do you always use the Admin account for routine computer use ?
