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:

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