If you are 100% sure you this file is not needed or required and has been created by yourself, I would try to remove the item with a program called -->>
Hijackthis<<--
It can remove files and folders on a reboot but no guarantees are offered or given
This program is a powerful tool and I urge you not to experiment with it to try and remove other items which you may
think are not required.
Webuser has a specialist -->>
forum<<-- to assist users with malware related problems and this tool is used under guidance from an approved malware removal specialist.
I'm not implying that this file is malware, but pointing out that a function of this tool has the capability to remove files or folders which may have been created by malware and of course the capability to remove other files and folders that are not. Either way, removing the wrong files can render a machine useless.

Please look at this link . . . -->>
Delete a file on reboot<<-- which shows you how to navigate to and remove a file via the Hijackthis interface.
If you are unsure about using this tool,
don't use it.
