I even tried renaming the mbam.exe to abc.exe and tried running it both in normal mode and safe mode. The problem still persists. Can somebody help me? Thanks a lot in advance.

This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.

Hi boopme,

Thanks a lot for the reply. I followed your instructions and ran the registry file. But the problem remains. Malware still disappears. I am using Windows XP. Please let me know what to do next.

Thanks a ton for your help.

Regards,
Kramer

Lets try this way.

Please click Start > Run, type inetcpl.cpl in the runbox and press enter.
Click the Connections tab and click the LAN settings option.
Verify if "Use a proxy..." is checked, if so, UNcheck it and click OK/OK to exit.


Reboot into Safe Mode with Networking
How to enter safe mode(XP/Vista)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.


>>>> Download this file and doubleclick on it to run it. Allow the information to be merged with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now reboot to Normal and run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Troubleshoot Malwarebytes' Anti-Malware

Please ask any needed questions,post logs and Let us know how the PC is running now.

Hi boopme,

I followed your instructions and I could succesfully run rkill.exe. Then I installed Superantisypware and after it starts scanning for 16 seconds, it disappears. I tried running all the versions of rkill.exe and all of them run without complaint (screen becomes blank as you mentioned). But still I think that the infection is still alive and kills superantispyware. I want to provide more information but the logs were not generated by the scan. So please let me know what information I should post that will be useful for detecting what the problem is.

Thanks a lot for helping me out with this. Waiting for your further instructions.

Regards,
Kramer

Forgot to mention. I even tried the portable version of the superantispyware and same problem persists.

Thanks,
Kramer

Hi,

One more observation. I ran all the versions of rkill and I did not see any log file displayed with the list of processes that are killed by it. So does this mean that rkill program was not able to run successfully and hence the infection background process is still running?

Thanks,
Kramer

Also, there is a process shown in the task manager, both in safe mode and normal mode, with the name 3498460175:4038818095.exe which does not gets killed with rkill.exe. I am suspecting this is the infection process.

I have the same virus. It doesn't appear to do anything but interfere with the malware scanners I have on my computer. Malwarebytes and Superantispyware. They appear to start then they disappear. ALSO they only do that once, attempts to run either program again give an error message that says windows cannot find that file. Must be a dozy!

Yes, I have the exact same behavior. But if we are unable to run malwarebytes or superantispyware, we will not be able to locate other trojans/infections that could be potentially residing in the machine right? Thats why want to get it removed. "boopme" please help!

Reading other posts.. I believe we have the ZeroAccess / Max++ rootkit. I refer you and our helper to this page.

http://www.sectechno.com/2011/09/16/zeroaccess-rootkit-max-new-variants/


I believe the file you mentioned is causing this.

I hate to tag on here but after making a lengthy post on another board here I came across your post. Now I feel like an idiot for making that post. But now I don't feel lonely since at one point I was thinking I was the only person with this problem. I am having the EXACT same situation as you. The only difference is my numbers are different. They are 3159867378:222341187.exe that's in the task manager. I too believe this is the culpit as it's being run by the system per task manager, I see no way around this God forsaking thing!

Hello. This is correct thar is the rootkit

EDIT: do not run and post a ComboFix log. ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use.

We need to move you all to your own new topics.. Lets see if we can run these.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.
