Need help with "panther"

A file named panther has appeared in my windows file. My antivirus program hasn't detected anything and I've experienced no ill effects but I don't know where it came from. I didn't knowingly install it. I checked for "panther" and it sounds pretty old. I've run a cleaner in safe mode and it didn't detect it either. Should I be concerned? Can I just delete this file and forget about it? What do you think?

You're right I should have told you the OS in the first post.
And you are also right that it is Vista.
From the links you posted I gather that the thing is supposed to be there.
I thank you for your assistance.
