The file appears to be the bootloader component of Grub4Dos
, a tool for booting computers from a GRUB-style boot manager.
If the above sentence makes any sense to you then you will probably be able to remember doing something that caused the file to be placed there. If you don't, then we have a minor mystery.
Grub4DOS is most commonly used in BIOS flash utilities, special tools that update the low-level software which runs all your hardware. Grub4DOS is also used as a major component of Wubi
, a tool which allows you to install Ubuntu Linux within Windows. However, neither of these possibilities account for the fact that the file's name appears to be completely random.
In any case, the file itself is harmless. It may be enlightening if you looked at the Creation Time attribute of the file, which might jog your memory by specifying the day and time the file was created.
