Hi, I'm running Windows XP Home Edition SP3. Yesterday one of my office computers started being overtaken by the System Check malware. It was very slow and I was unable to use Internet Explorer so on a different computer I researched and came across the "Remove System Check (Uninstall Guide)". I followed all the instructions as closely as possible. I downloaded all the programs (RKill or iExplore.exe, TDSSKiller, and Malwarebytes) onto a USB flash drive from a clean computer and installed them on the infected one after booting in Safe Mode with Networking. After the programs were all installed and run and Malwarebytes reported 57 objects found it asked to be restarted to complete the removal process, which I did. After rebooting in Safe Mode I ran Malwarebtes again with 0 results. But after rebooting in Normal mode System Check starts right back up again like nothing's changed. I am only able to use this computer in Safe Mode now. Help!

Hi

Please do the following:

Go to Start > Run > type cmd into the open run box > OK to open a command window:


Copy/paste the following into the command window:

ren c:\documents and settings\all users\application data\CgQLmwtUoq.exe CgQLmwtUoq.vir



NEXT


Please run the following:


Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Posted Image

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

  • Click on Yes, to continue scanning for malware.
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

Hi, thanks for replying so soon!

When I copy/paste the command into the cmd box all I get is the message: The syntax of the command is incorrect. I tried typing it out with the same result.

Is this supposed to happen? Do I continue anyway? I have not run ComboFix yet.

Go to Start > Run > type cmd into the open run box > OK to open a command window:
Copy/paste the following into the command window:

ren "c:\documents and settings\all users\application data\CgQLmwtUoq.exe" CgQLmwtUoq.vir

I'm sorry, but I got sick over the weekend and my boss was impatient and called in a local IT to work on the computer. So please consider this case closed.

Thank you very much for your time and effort. :) I would have liked to see how you resolved this but now I'll just have to wait on the IT.

Thanks again!
