Persistent Trojan Horse Agent_r.XJ..HELP

Do you have your Windows boot CD? What operating system are you running there?

 

Do you have your Windows boot CD?

 

I want you to download Combofix to your desktop

Now follow the information in this link to install the Recovery console if you do not already have it.

Installing Windows Recovery Console Using ComboFix

Once done...

Reboot your machine and when the Boot Menu flashes up - select "Microsoft Windows Recovery Console"
(you need to be very fast with the arrow key as you only have a couple of seconds before it defaults to the windows XP bootup)

When you get to the above screen, take note of the number that references your operating system.

If it's '1' like the picture above, type 1 and press Enter

Next type FIXMBR

If it ask if you're sure you want to write a new MBR, answer 'Y'

Then type EXIT to reboot the machine.

With that done, please post back and let me know how things are now. Then there will be other scans to work on afterwards as part of the Read and Run Me First procedures.

 

Try this:

Please download aswMBR.exe ( 511KB ) to your desktop.

Double click the aswMBR.exe to run it.

Click the "Scan" button to start scan

http://i1111.photobucket.com/albums/h479/MysticalMagpie/5.png?t=1303863051

On completion of the scan click save log, save it to your desktop and post in your next reply.

 

Now run what you can of the below.

READ & RUN ME FIRST. Malware Removal Guide

Please also download MBRCheck to your desktop

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some data on it
• Right click on the screen and select > Select All
• Press Control+C
• Open a notepad and press Control+V
• now please ATTACH that report to this thread as well as the other requested logs.

 

OK. Now run what you can of the below.

READ & RUN ME FIRST. Malware Removal Guide

 

So after running the below I need to see logs from each:

• SUPerantispyware
• Malware Bytes
• Combofix (Download the current version from the link just to be sure you have the latest)
• MGTools

Also TDSSKiller (Only run that after running the rest) - try that again and attach the log if successful.

 

The MBAM log shows "Not selected for removal." Did you indeed fix everything it found?

I see a bit of malware to remove in your Combofix log, but let's try and get a full set of logs from MGTools. But first check to see if TDSSKIller will now run for you! Let me know.

Please do this, click Start, Run and enter cmd and click OK. This will open a command prompt window. In the command prompt window, enter the below commands each followed by the enter key. Note there is a space after the cd

cd \MGtools
GetLogs.bat

Do you now have a C:\MGLogs.zip?

 

First off, if you have both Avast and Microsoft Security Essentials installed then you need to uninstall one of them immediately before we continue.

Please disable Spybot's TeaTimer.

How to disable Spybot's TeaTimer

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::

Folder::
c:\windows\system32\config\systemprofile\Application Data\whitesmoketoolbar
File::
c:\program files\051120109444040.bat
c:\windows\TEMP\Yh1.exe
c:\windows\TEMP\Yh0.exe
Registry::
[HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run]
"GHWAUC6NNZ"=-
"PT25DHYRAW"=-
"SvrWsc"=-

• 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

• 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.

If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.


Download OTL to your desktop.

• Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
• Vista and Windows 7 users Right-click OTL and choose Run as Administrator)
• When the window appears, underneath Output at the top change it to Minimal Output.
• Check the boxes beside LOP Check and Purity Check.
• Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.

When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.

Attach both of these logs into your next reply.

Rename C:\MGTools.exe to 123.com and see if it will now run for us.

Tell me how things are running. Of course I think the infection is still in place, and it is an MBR infection, so we may have to start thinking about other ways to repair it if you cannot locate your boot CD or borrow one. Perhaps we could use Hiren's CD to fix the MBR. See what was posted in message # 12 of the below thread and see if you can get this CD to run. If you still need special drivers to access your drive, you will need to post in the Software Forum on how to do this.

whistler/black internet@mbr again!


What's inside of ths folder?
c:\program files\Tdds

 

Then let's do this.

You need to use your Windows XP CD to boot to the Recovery Console and run the fixmbr to clear a Master Boot Record infection that you have.

You can read the below to help you do this:

http://support.microsoft.com/kb/307654


After running the fixmbr command then boot back to normal mode Windows and try running TDSSkiller now. Then attach the log. Also explain if you are still having any malware problems.

 

I'll get back to you on that. I think we will be okay but hang in there and I will reply after asking colleagues.

 

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

After clicking Fix, exit HJT.

* 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.

Then attach the below logs:

* C:\ComboFix.txt
* C:\MGlogs.zip

Make sure you tell me how things are working now!

 

You need to boot from a Windows Boot CD and run fixmbr. To answer your questions. See inline replies in bold brown.

 

Okay then the options that remain are:

1. Slave this infected hard disk to a another Windows XP computer and use this second/clean computer to repair the MBR of the infected drive. You will need to use specific commands give in the Microsoft link to repair the second hard disk rather than the first.
2. Backup your important data, delete partitions, repartition, format and reinstall.

 

The MBR infection has not impacted your data. However you had many other infections too. They probably have not infected personal data/files. You just need to be very careful about what you backup and only backup necessary personal files and not just everything you have downloaded/installed since there is always a risk that the executables carry infections.

As long as you get the correct MBR fixed, it should be okay.
