• Double click Rkill to run it
• A command window will open then disappear upon completion, this is normal
  
  • If this does not happen... delete the file, then download & use the next link provided
  • If it does not work, repeat the process & attempt to use one of the remaining links until the tool runs
• Do not reboot your machine until asked to do so. If no version of Rkill would run, please let me know
• When finished, Notepad will open with a log file, automatically saved at C:\rkill.log
• Copy/paste the contents of the rkill.log file in your next reply
• Leave Rkill on the Desktop unless instructed otherwise

Note: If you get an alert that Rkill is infected, ignore it. The alert is a fake warning given by rogue software, trying to "protect" itself from being terminated or removed. If you see such a warning, leave the warning on the screen, then run Rkill again. By not closing the warning, this sometimes allows you to bypass the malware's attempt to protect itself, so that Rkill can perform its routine.
