    • Please download TDSSKiller to your desktop.
    • See the download links under this icon: [​IMG]
    • Save tdsskiller.zip to your desktop.
    • Then extract TDSSKiller.exe onto your desktop.
    • Double-click TDSSKiller.exe to open the program. ( If using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor. )
    • The Open File - Security Warning window should appear.


    • Press the Run button and TDSSKiller should open.
    • Some rootkits will prevent TDSSKiller from opening.
      • If this is the case for you, skip TDSSKiller for now and continue with the rest of the steps of the Malware Removal Guide.
    • Here is what TDSSKiller looks like upon successful launch.


    • Click the Start scan button.
    • Be patient as TDSSKiller scans your system for rootkit activity.
    • Depending on whether TDSSKiller found anything or not, you will most likely see one of the following types of screens below when the scan is finished.

      Example #1: No threats found


      Example #2: Threats detected


    • VERY IMPORTANT: In the event that threats are detected, allow TDSSKiller to perform the default action by simply pressing the Continue button.
    • Do NOT change the default action on your own unless instructed by a malware helper! Doing so may render your computer unbootable.
    • If threats were detected, TDSSKiller will require a reboot in order to attempt to clean the system.


    • Press the Reboot computer button.
    • With more difficult versions of this rootkit, you may see a black background (ie., no desktop ) with only the below windows showing. Simply press the Run button and TDSSKiller should open itself again and your desktop should reappear.


    • Now go to the root of your C: drive and find the TDSSKiller log(s).
    • They are named like this: TDSSKiller.
    • Keep this text file handy in case you are still experiencing problems and need to create your own thread in our Malware Removal forum.
    • If you are still having trouble, remember to attach this text file once you are finished with the remaining procedures. (See: HOW TO: Attach Items To Your Post )
