I don't understand why we needed to do this part the .dll file and .exe???
Because those are two nasty files that must go. 
It is a script designed to make combofix remove the files.
If you haven’t run the fix yet, please do so now and post just the combo fix log.
If you have tried doing that fix, it didn’t work, the files are still there. So…
Please download the OTMoveIt http://download.bleepingcomputer.com/oldtimer/OTMoveIt.exe by OldTimer.
Save it to your desktop.
Please double-click OTMoveIt.exe to run it.
Copy the file paths below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy):
C:\WINDOWS\pmkret.dll
C:\WINDOWS\monhop.exe
Return to OTMoveIt, right click on the “Paste List of Files/Folders to be moved” window and choose Paste.
Click the red Moveit! button.
Copy everything on the Results window to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy), and paste it on your next reply with a new DSS log.
Close OTMoveIt
If a file or folder cannot be moved immediately you may be asked to reboot the machine to finish the move process. If you are asked to reboot the machine choose Yes.
