I've spent many hours trying to get rid of avsystemcare files on my machine. I run a scan using spyhunter and it seems i got rid of them. When i reboot, they are back in the registry. All the rest are gone...or so spyhunter says. I can find those in the registry...delete them...but upon reboot they are back. Since the attack, i can not get into my control panel, or my computer propeties or any type of admin stuff. Also on boot up, when it gets to my desk top, it says can not find C:\windows\system32\mljjg.exe or C:\windows\shell.exe. Help!

Edit: Moved topic to the more appropriate forum. ~ Animal

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 OTMoveIt by OldTimer and save to your Desktop.
  • Double-click on OTMoveIt.exe to launch the program.
  • Copy the file(s)/folder(s) paths listed below - highlight everything in the quote box and press CTRL+C or right-click and choose Copy.

C:\windows\system32\mljjg.exe

  • Then in OTMoveIt, right-click in the open text box labeled "Paste List of Files/Folders to be Moved" and choose Paste.
  • Click the red MoveIt! button.
  • The list will be processed and the results for each line will be displayed in the right-hand pane.
  • Highlight everything in the Results window, press CTRL+C or right-click, choose Copy, right-click again and Paste it in your next reply.
  • Click Exit when done.
  • A log of the results is automatically created and saved to C:\_OTMoveIt\MovedFiles \mmddyyyy_hhmmss.log <- the date/time the tool was run.
  • Please copy/paste the contents of that log in your next reply.
-- Note: If a file or folder cannot be moved immediately you may be asked to reboot your computer in order to finish the move process.
If asked to reboot, choose Yes.


Caution: Be careful of what you copy and paste with this tool. OTMoveIt is a powerful program, designed to move highly persistent files and folders. Not following the directions as instructed or using incorrectly could lead to disastrous problems with your operating system.


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

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
