Please download ComboFix from one of the following links, and follow the instructions below to run it. Save as Combo-Fix.exe during the download. ComboFix must be renamed before you download to your Desktop

* IMPORTANT !!! Save Combo-Fix to your Desktop

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
    See HERE for help
  • 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: (This applies to Windows XP systems only) If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

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

Click on Yes, to continue scanning for malware.

When finished, ComboFix will produce a log.

Note:

1. Do not mouseclick combofix's window while it's running. That may cause it to stall!

2. Remember to re-enable your anti-virus and anti-spyware before reconnecting to the Internet.

Attach logs for: (USE THE "MORE REPLY OPTIONS" BUTTON TO BE ABLE TO DO THIS)

  • ComboFix (C:\combofix.txt)

Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!

Hi

Tried the first Combofix link, wouldn't download, said there was no internection connection - there actually was. Tried second Combofix link, this downloaded successfully.

Ran Combo-fix.exe, it appeared to be running smoothly; went to 100% then computer crashed, re-booted and i received the message "system has recovered from a serious error". Tried the procedure again - same result. Thanks.

Here's a link to an article from Microsoft on how to reset Internet Explorer's settings, including a Microsoft FixIt that is capable of doing it for you if you would prefer.

Can't access their site at all. Tried various different routes to get through - non successful. I'm having exactly the same problem with McAfee. Tried another random website and got through perfectly.

There is a possibility that one of the utilities in the attached rkill.zip file will help as well. Just extract it somewhere, and run the utilities one at a time. If they work, a window should pop up, and you should see some information.

After running them, try to download ComboFix again, and if that works then get me a log.

Ran TDSSKiller it found a rootkit. Followed instructions to cure. Ran again after reboot to double check - all clear. Computer still displaying same symptoms though. Microsoft security essentials still won't update, can't access help page; McAfee still inactive

Finally ran Combofix, took a long time and whilst running the following message flashed up about 40 times "Windows cannot find 'NIRKMD' . Make sure you typed the name correctly, and then try again. To search for a file, click the start button, and then click search" Don't know if this has any relevance as combofix appears to have run successfully but i though i'd better make note just in case of future issues. I've attached log for Combofix, will check in again tomorrow. Thanks.

Looks like that was a pretty bad infection. From that log, it looks like Safe Mode is broken, and we'll need to fix it after we finish some more cleanup.

I have written a script that will tell ComboFix how to delete some stuff I saw in your log. Here are instructions on what to do with the script:

  1. Turn off your Anti-Virus software.
  2. Click your Start button, go to All Programs (or just Programs on Vista and Windows 7), go to Accessories, and then open Notepad.
  3. Please copy and paste the contents of the box below into Notepad (here is a link to instructions if you do not know how to copy and paste):
    http://support.emsisoft.com/topic/7475-my-pc-is-infected-and-i-cant-run-otl/

    c:\documents and settings\LocalService\Local Settings\Application Data\dbwsqsdv\lhofbvjm.exe
    
    Suspect::

    Registry::
    [HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon]
    "Userinit"="C:\WINDOWS\system32\userinit.exe,"


  4. Save this as a Text Document named CFScript in the same location as ComboFix (which should be on your desktop).
  5. Close Notepad and verify that the CFScript file is saved on your desktop.
  6. Referring to the animated picture below, click the left mouse button on top of the CFScript icon on your desktop, then holding the mouse button down drag the CFScript icon on your desktop onto the ComboFix icon, and then drop it (let go of the mouse button) on top of the ComboFix icon:
    CFScriptB-4.gif

When finished, it will display a new log in Notepad. Please attach that log to a reply the same way you did before. If you prefer, you can save the log on your desktop to make it easier to find.

OK, we're going to need to try another CFScript. Here are instructions again on what to do with the script:

  1. Turn off your Anti-Virus software.
  2. Run Rkill just to make sure that nothing interferes with ComboFix while it runs the script. Go ahead and run all three of the ones in the ZIP file I attach to a post earlier, just in case.
  3. Click your Start button, go to All Programs (or just Programs on Vista and Windows 7), go to Accessories, and then open Notepad.
  4. Please copy and paste the contents of the box below into Notepad (here is a link to instructions if you do not know how to copy and paste):

    "LhoFbvjm"=-


  5. Save this as a Text Document named CFScript in the same location as ComboFix (which should be on your desktop).
  6. Close Notepad and verify that the CFScript file is saved on your desktop.
  7. Referring to the animated picture below, click the left mouse button on top of the CFScript icon on your desktop, then holding the mouse button down drag the CFScript icon on your desktop onto the ComboFix icon, and then drop it (let go of the mouse button) on top of the ComboFix icon:
    CFScriptB-4.gif

**NOTE**
If ComboFix wants to update, then please allow it to do so.

When finished, it will display a new log in Notepad. Please attach that log to a reply the same way you did before. If you prefer, you can save the log on your desktop to make it easier to find.

Hi tring to run combofix after following other instructions. It is telling me to close McAfee or it might affect results, harm computer. I have no access to McAfee at present, have tried to open every which way - no reponse - shall i run anyway?

McAfee will need to be disabled before running ComboFix. If it is working, then it will not allow ComboFix to run properly.

If you are unable to do anything about McAfee, then try following the instructions at this link to remove McAfee. You can reinstall it once we get your computer cleaned up.

After disabling or uninstalling McAfee, please try the latest CFScript instructions again.

Yes, every version of ComboFix will expire after a certain period of time, and you will need to download a new one. If you run Rkill first, then are you able to download ComboFix from one of the links below?

OK, there should be two ZIP archives in the following location on your computer:

C:\Qoobox\Quarantine

Their name will most likely start out [4] followed by the date and time. Windows may call them a Compressed (zipped) folder. Please send me a private message on the forums with these two files attached.

OK, ComboFix isn't deleting part if the infection, so we need to try a different utility. Here are some new instructions:

1. Please download The Avenger from this link, and make sure to save it on your Desktop.

  • Right click on the Avenger.zip folder and select "Extract All..."
  • Follow the prompts and extract the avenger folder to your desktop

2. Copy all the text contained in the CODE box below, and it will be pasted into The Avenger in a later step (if you do not know how to copy and paste, then there are instructions at this link):

Folders to delete:
c:\documents and settings\LocalService\Local Settings\Application Data\dbwsqsdv

Note: the above code was created specifically for the person requesting assistance in this forum topic, and it is based entirely on the logs they supplied from their computer. No one else should attempt to run The Avenger with this script, as it may damage their computer!

3. Now, open the avenger folder on your desktop and start The Avenger program by double-clicking on its icon.

  • Please paste the contents of the CODE box above (which you should have already copied) into the white box in The Avenger (see example picture below).
  • Click on the Execute button in the low-right corner (see example picture below).
    paste_script_into_avenger.png
  • Answer "Yes" twice when prompted.

4. The Avenger will automatically do the following:

  • It will Restart your computer. ( In cases where the code to execute contains "Drivers to Delete", The Avenger will actually restart your system twice.)
  • On reboot, it will briefly open a black command window on your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
  • The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.

5. Please copy/paste the content of c:\avenger.txt into your reply, and we will go from there.

Ran Combo-fix but didn't finish successfully. Ran full check and rebooted but didn't come back after reboot. Stopped on Welcome screen and stayed there. I waited for 15 mins and nothing happened, so had to turn off computer and restart. Shall i try again or is this a symptom or some other problem? Obviously no log came up.

This is a persistent infection. We're going to have to try something else. Make sure you run Rkill before proceeding with the following instructions.

Please run a scan with Malwarebytes' Anti-Malware by following the instructions below:

  1. Please download and install Malwarebytes' Anti-Malware from one of the three mirrors listed below (beware of excessive advertising on some of the download pages):

[*] When first running Malwarebytes' Anti-Malware, it will ask you if you want to operate it in a free trial mode. You can say no to this (the trial can be unlocked again at a later time if you want to try it).

[*] Make sure to go to the Update tab and click the Check for Updates button to get the latest database.

[*] Switch back to the Scanner tab and run a Quick Scan.

[*] When it is done, remove anything it finds.

[*] Whether or not it finds anything, you should be presented with a log in Notepad, which you should save to your desktop.

[*] Attach the log you saved on your desktop to a reply for me to take a look at. You can attach files to a reply by clicking the More Reply Options to the lower-right of where you type in your reply. When the page loads, there will be a button right below the box to type in (on the left side) that says Choose Files... which will allow you to select the log file to attach it.

That's the same stuff that ComboFix keeps showing. I doubt that it was actually removed. I need some more information to know what's going on.

Please download GMER from this link. Note that the file will have a random name, so make note of the file's name and save it to the root of your C: drive.

  1. Disconnect from the Internet and close all running programs.
  2. Temporarily disable any real-time active protection so your security program drivers will not conflict with this file.
  3. Click on this link to see a list of programs that should be disabled while running GMER (please try to avoid the advertisements on that page).
  4. Double-click on the downloaded file to start the program. (If running Vista, right click on it and select "Run as an Administrator")
  5. Allow the driver to load if asked.
  6. You may be prompted to scan immediately if it detects rootkit activity.
  7. If you are prompted to scan your system click "No", save the log and post back the results.
  8. If not prompted, click the "Rootkit/Malware" tab.
  9. On the right-side, all items to be scanned should be checked by default except for "Show All". Leave that box unchecked.
  10. Select all drives that are connected to your system to be scanned.
  11. Click the Scan button to begin. (Please be patient as it can take some time to complete)
  12. When the scan is finished, click Save to save the scan results to your Desktop.
  13. Save the file as Results.log and please attach it to a reply by using the More Reply Options button to the lower-right of where you type in your reply (you may need to ZIP the log by right-clicking on it, going to Send to, and clicking on Compressed (zipped) folder before you can attach it).
  14. Exit the program and re-enable all active protection when done.

Still no internet access.

Considering the nature of the infection on your computer, it is possible that it is infected with a rogue. Rogues pretend to be antivirus software claiming that your computer is infected, and usually trying to get you to pay money to remove whatever they claim they detected. In reality, the rogue is the infection, and just allow Microsoft Security Essentials to finish its scan and then remove anything it finds.

You may also want to try Malwarebytes' Anti-Malware again after Microsoft Security Essentials is done.

Do you have access to a good computer with a CD burner? It may be necessary to use a bootable anti-virus disk to clean this infection up.

hi we tried, downloaded onto an external cd drive as mine doesn't have one, unfortunately the process was unsuccessful. i've taken pc to a shop now for repair - was becoming impossible to fix with no internet access and couldn't cope with another late night. Thanks for you help, fingers crossed it gets fixed.

You're welcome. I'm sorry we couldn't be of more assistance in getting it fixed.

A good repair shop will have utilities such as customized BartPE disks or UBCD4Win disks where they can run all sorts of anti-virus scans from a bootable CD. Theoretically they will also have techs capable of looking at your system and manually removing anything that anti-virus software is missing.

Since it appears that the need for this topic is now over, I'm going to go ahead and close it. If you require any further assistance, then please let me know. This topic can be reopened at any time. ;)

Note: The instructions in this forum topic have been customized based on the logs posted by the person asking for assistance. Please do not attempt to follow any of the instructions in this forum topic, as they could cause damage to your computer. If you require assistance, please start here if you believe your computer is infected, and one of our experts will be happy to assist you by analyzing your logs.
