If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware. You can uninstall RogueKiller and HitManPro.
2. Go back to step 4 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
4. If running Vista or Win 7, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
