Thanks!  I've committed a fix upstream to avoid sectors matching this
signature.

Title:
  Signature of Acer utility corrupting grub2

Status in “grub2” package in Ubuntu:
  In Progress

Bug description:
  I don't know if you are still interested in signatures of Windows
  utilities corrupting grub2, but in case you are, I have attached two
  hexdumps I made last year when I had this problem with Ubuntu 10.10
  and an Acer registration utility.  Sorry they are not dd dumps, but
  it's the same information you requested and I think it is fairly clear
  what happened (an entire block was overwritten at sector 18 / offset
  0x2400).  Searching for the signature with Google, I also found these
  URLs, which report the exact same contents at the same offset:
