Alright, so I know I have this file called popcorn72.exe. I ran sophos antivirus, and it quarantine it. I then tried to delete it from the registry, but I couldn't find it under runcontrolpanel. What happened to it? When I try to delete the file from the c drive, it says "Access is Denied."

Need any more info? Thank you so much for helping me...

I did a search for popcorn72 on these forums, but it didn't turn up anything...
