Dear Bleepingcomputer,
I'm writing in the hope that you will be able to help. Like many other people, I got hit by the nasty medichi.exe & medichi2.exe malware. I followed many forums online and learned that every occasion is different and following those instructions might prove useless or even fatal to my system.

The symptoms are:
- disabled control panel
- copying window appearing every 3 or so minutes
- Windows Security Alert appearing, prompting me to download Spyware Remover (which I know, by now, that it is illegit, it even has a spelling error)
- my Internet connection not working (I'm on another computer, and have CDs ready to download programs if necessary)

In different forums I read about different antimalware applications, but so far no one has worked. I get the message that I'm not authorized to do this and that... I'm ready to prepare logs for you, if you could help, please just instruct me which application to use. I have just about every application ready on CD to be transferred to my infected desktop.

Thank you!

  • Double click SDFix.exe and it will extract the files to %systemdrive%

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options.

  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services or Registry Entries found then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts, the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load, the SDFix report will open on screen and also save a copy into the SDFix folder as Report.txt.
  • Copy and paste the contents of Report.txt in your next reply.
-- If this error message is displayed when running SDFix: "The command prompt has been disabled by your administrator. Press any key to continue..."
Please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\swreg IMPORT %systemdrive%\SDFix\apps\Enable_Command_Prompt.reg
Press Ok and then run SDFix again.

-- If the Command Prompt window flashes on then off again on XP or Win 2000, please go to Start Menu > Run > and copy/paste the following line:
%systemdrive%\SDFix\apps\FixPath.exe /Q
Reboot and then run SDFix again.

-- If SDFix still does not run, check the %comspec% variable. Right-click My Computer > click Properties > Advanced > Environment Variables and check that the ComSpec variable points to cmd.exe.
%SystemRoot%\system32\cmd.exe
