Hello,

We need to burn a CD on a clean PC so we can run your infected PC outside of Windows.

Please print these instructions and follow them:

  • On the clean computer:
  • Download OTLPEStd.exe to your desktop
  • Ensure that you have a blank CD in the drive
  • Double click OTLPEStd.exe and this will then open imgburn to burn the file to CD


    On the infected computer.
  • Reboot your system using the boot CD you just created.
    Note : If you do not know how to set your computer to boot from CD follow the steps here
  • As the CD needs to detect your hardware and load the operating system.
  • Your system should now display a Reatogo desktop.
    Note : as you are running from CD it is not exactly speedy
  • Double-click on the OTLPE icon.
  • Select the Windows folder of the infected drive if it asks for a location
  • When asked "Do you wish to load the remote registry", select Yes
  • When asked "Do you wish to load remote user profile(s) for scanning", select Yes
  • Ensure the box "Automatically Load All Remaining Users" is checked and press OK
  • OTL should now start. Change the following settings.
    • Change Drivers to All
    • Change Standard Registry to All

    Under the Custom Scan box paste this in If you're unable to access the internet on the infected PC then use a USB stick to copy and paste

    /md5start
    eventlog.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll

    ntoskrnl.exe
    /md5stop
    %SYSTEMDRIVE%\*.*
    %systemroot%\*. /mp /s
    %systemroot%\System32\config\*.sav

  • Press Run Scan to start the scan.
  • When finished, the file will be saved in drive C:\OTL.txt
  • Copy this file to your USB drive if you do not have internet connection on this system.
  • Confirm that it has copied to the USB drive by selecting it
  • Please post the contents of the C:\OTL.txt file in your reply.
