Cannot Fully Heal Packed.Generic.200 virus, cannot find globalroot

I recently got hit with the Antivirus 2009 malware. I have managed to clean almost everything using malwarebytes, superantispyware, hijackthis, and combofix. The only thing that keeps showing up is a file randomly named uacyqopkvxe.dll located at:

 

globalroot\systemroot\system32\uacyqopkvxe.dll

 

Norton Internet Security dectects it as Packed.Generic.200. I tried following the instructions on norton's webstie but norton cannot delete the file. I tried searching for the file on my own but cannot find it. Where is the globalroot directory located?
