First make sure you have a current and complete backup of your hard drive.


Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and erase the hard drive. Then select "Reinstall OS X".



When booting for the first time don't create a new admin user account but select Migration Assistant to recover your files from Time Machine.

Try downloading and running Find Any File to search for the file.  Do the following search: 


1 - Name contains IRRVNMLV


Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion. Check carefully before moving it to the Trash bin. See where it's located first.


FAF can search areas that Spotlight can't like invisible folders, system folders and packages.
