I think I'm infected with something called "medichi.exe". I've tried looking up how to get rid of this, but nothing is working! I can't open much of anything- like the control panel, task manager, registry editor, or even programs like paint, wordpad, etc. (They aren't "found.") The task manager has been "disabled by [my] administrator". When I run it in safe mode I can log into my account or "administrator"- I've tried both, and I am able to see the control panel while I'm in "administrator" but I can't do anything in it. (The control panel doesn't even show up when I go into mine.) I can't install anything- when I try to run something I just installed, it says it "cannot be found." I am so lost- I've tried Yahoo! Answers, they've led me to a few sites, I've tried doing what they say but I'm still so stuck! Help!!

One or more of the identified infections is a backdoor Trojan. Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to to gain unauthorized access to a computer and take control of it without your knowledge. Read the Danger: Remote Access Trojans.

If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay and forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach.

Although the backdoor Trojan has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the backdoor Trojan has been removed the computer is now secure. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS - "When should I re-format?".

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. If you wish to proceed, please do the following.

Please download SDFix by AndyManchesta and save it to your desktop.
alternate download
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Double click SDFix.exe and it will extract the files to %systemdrive%
  • (this is the drive that contains the Windows Directory, typically C:\SDFix).
  • DO NOT use it just yet.
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. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Open the SDFix folder and double click RunThis.bat to start the script.
  • 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
