Basically, I decided to download a movie online. When I opened the .exe it came up with something to do with PileFile. I was extremely worried, so I closed it but nothing happened for a day or two . But now, I decided to uninstall a program, and I was looking down my list when I see Oxy and PileFile Reminder. I try to remove it, but it comes up with 'You do not have sufficient access to uninstall Oxy/PileFile Reminder. Please contact your system administrator', even though I am the administrator. Help me please.
