This is a left-over file that was not removed by the program's
uninstall routine.

Trying to delete it results in the "locked or in use" error.

File Assassin's "unlock" routine reports that the file is not locked.
However File's Assassin's "delete file" command results in "unable to
delete."

First off: boot to safe mode, you should be able to delete it from there.
If that does not work, boot from a Linux live cd...for sure you will be
able to delete it then. (I'd probably rename it first just in case it
ends up being some file needed for booting)
