Hi, I was wondering if anyone could help me figure out if a file I found on my C drive, that's labeled "Panther". It says its a form of windows, but I've never seen a windows down load look like this does. It looks like this $Windows~BT. I've tried to delete it, but it won't let me. I've tried going to administrator permissions & changing them & then trying to delete & nothing. I've rebooted my computer to factory settings & wiped everything out, still there. Please can someone tell me if this is a virus or a legit windows download. And if its a virus, how I can remove it off my laptop
