Please help me sort this one out. I've downloaded an mpeg video file from LimeWire. I cannot play the file. I cannot delete the file. I cannot even move or rename the file, no matter how I try to do so. There doesn't seem to be any negative impact on the speed or operation of my system, but it still frustrates me to be stuck with this file and I am worried that there could potentially be some sort of virus or spyware locked up in this file, so full effect of which has yet to become apparent. I'd like it gone.

Can anyone suggest a way to rid myself of this unwanted file?

Thank you all for help.

Dan
