dupler malware

Hi there and welcome. I am currently reviewing your logs and will get back to you with a set of instructions in the next post I make to you.

 

IP resolves to the Russian Federation.

Tell me more about it, What .exe file is within it?

Try this:

For the external Hard Drive and a USB stick.

Insert your flash drive before we begin. Hold down the Shift key when inserting the flash drive until Windows detects it to bypass the autorun feature. This will keep the autorun.inf from executing automatically.

Please have all your removable storage devices ready for disinfection.

Download Flash Disinfector by sUBs and save it to your desktop.

• Double-click Flash_Disinfector.exe to run it.
• Your desktop and icons may disappear. This is normal.
• It will do a cleanup of removable storage devices, and write a protected Autorun.inf file to help prevent re-infection.
• Follow any prompts that may appear.
• The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
• Wait until it has finished scanning and then exit the program.
• There will be no GUI interface or log file produced.
• Reboot your computer when done.

Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder. It will help protect your drives from future infection.

What do you know of this file?

...and this folder?

Now we need to use ComboFix

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:

Code:

KILLALL::

File::
C:\Documents and Settings\All Users\Application Data\5680CD72FA.sys

FileLook::
c:\documents and settings\All Users\Application Data\BD0EDAA4DF.sys

DirLook::
c:\documents and settings\Administrator\Application Data\chc.4875E02D9FB21EE389F73B8D1702B320485DF8CE.1
C:\WINDOWS\system32\1025
C:\WINDOWS\system32\IME
C:\WINDOWS\system32\drivers\INF
C:\WINDOWS\System32\drivers\system32

• Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
• At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
• You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
• Now use your mouse to drag CFscript.txt on top of ComboFix.exe
  
  http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
  
  
• Follow the prompts.
• When it finishes, a log will be produced named c:\combofix.txt
• I will ask for this log below

Note:

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


Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this also answer any questions that I may have asked you.

 

Could you address the questions that I asked, please.

 

Please go to Jotti's malware scan

(If more than one file needs scanned they must be done separately and logs posted for each one)

• Copy the file path in the below Code box:
  
  Code:

  c:\documents and settings\All Users\Application Data\BD0EDAA4DF.sys

• At the upload site, click the browse button.
• Use Windows Explorer to navigate to the file(s) we need scanned and click "submit file"
• Your file will possibly be entered into a queue which normally takes less than a minute to clear.
• This will perform a scan across multiple different virus scanning engines.
• Important: Wait for all of the scanning engines to complete.
• Once the scan is finished, Copy and then Paste the link in the address bar into your next reply.

Now we need to use ComboFix

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:

• Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
• At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
• You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
• Now use your mouse to drag CFscript.txt on top of ComboFix.exe
  
  http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
  
  
• Follow the prompts.
• When it finishes, a log will be produced named c:\combofix.txt
• I will ask for this log below

Note:

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

Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this. Do not forget the jotti results!

Let me know how things are running!

 

The jotti link will not open for me. But if you say it reported no threats then we'll go with that.

You didn't attach the logs. I'll be here waiting but I suspect final steps can be given very soon now.

 

Use windows explorer to locate the following emboldened empty directories:

• c:\windows\system32\1028
• c:\windows\system32\1031
• c:\windows\system32\1033
• c:\windows\system32\1037
• c:\windows\system32\1041
• c:\windows\system32\1042
• c:\windows\system32\1054
• c:\windows\system32\2052
• c:\windows\system32\3076

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     • Notes: The space between the combofix" and the /uninstall, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
7. Go to add/remove programs and uninstall HijackThis.
8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
   related to MGtools and some other items from our cleaning procedures.
9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
   • Refer to the cleaning procedures pointed to by step 7 of the READ ME
     for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
10. After doing the above, you should work thru the below link:
    • How to Protect yourself from malware!

 

If it's empty there's nothing to worry about, however if you really wish to be rid of it:

Now download The Avenger by Swandog469, and save it to your Desktop.

• Extract avenger.exe from the Zip file and save it to your desktop
• Run avenger.exe by double-clicking on it.
• Do not change any check box options!!
• Copy everything in the Quote box below, and paste it into the Input script here: part of the window:

• Now click the Execute button.
• Click Yes to the prompt to confirm you want to execute.
• Click Yes to the Reboot now? question that will appear when Avenger finishes running.
• Your PC should reboot, if not, reboot it yourself.
• A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.
