1. Please download The Avenger by Swandog46 to your Desktop.
  • Click on Avenger.zip to open the file
  • Extract avenger.exe to your desktop


2. Copy all the text (including the 'Files to delete') contained in the code box below to your clipboard by highlighting it and pressing Ctrl+C:

Files to delete:
C:\WINDOWS\system32\commib.dll
C:\WINDOWS\system32\lsasss.exe

Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

3. Now, start The Avenger program by clicking on its icon on your desktop.
  • Under "Script file to execute" choose "Input Script Manually".

  • On reboot, it will briefly open a black command window on your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
  • The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.
5. Please copy/paste the content of c:\avenger.txt into your reply along with a fresh HJT log by using Add/Reply
