windows 7 - I can't delete a file - even when using unlocker

Ok, so when I try to delete this from my desktop, I get this error:

When I click "See what's locking this" in lock hunter, I get this:

Now, I have a drive, called G:. I only have one physical drive, and it's D:. Also, I have NO virtual drive software installed, so I have NO clue how it got there. Right-clicking on G:\ and chosing eject doesn't do anything but change the logo, it still says the file size and whatnot. Here's the picture of the "What's locking this?" of the contained file:

But when I try to delete it...

Both of these files don't let me delete them. I had put win8install.iso as a virtual drive a while back, but I uninstalled that software (but can reinstall it if needed)

Starting this in safe mode doesn't work.

Answer

Get a Linux Live Cd, and get gparted, systemrescue or parted magic (any release would work, but a small distro for something quick). Burn it to cd/usb, and boot your computer to it. Mount the hd, and find the folder and delete it.

You can use Unetbootin to create the live cd or do it manually.
