Infected with a backdoor Trojan

Java(TM) 6 Update 21 <--- Uninstall outdated Java.

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::

RegLock::
[HKEY_USERS\S-1-5-21-2581610734-1340675633-1247259385-1006\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{AD31EF7A-187B-5B7C-0AAA-6520BD80F040}*]
@Allowed: (Read) (RestrictedCode)
@Allowed: (Read) (RestrictedCode)

File::
C:\Documents and Settings\Owner\Local Settings\Application Data\61af0b5oy074ma2d330
C:\Documents and Settings\All Users\Application Data\61af0b5oy074ma2d330
C:\Documents and Settings\Owner\Templates\61af0b5oy074ma2d330

• 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.

Reboot your machine and install the most current and up to date version of Java available here at the below link:

Java Runtime 6

Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

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

 

To uninstall Java see the below:

Try Revo Uninstaller.
Choose the option on the bottom of the list (#4). Be very careful while deleting the bolded registry items ONLY!! This software will create a system restore point for you as well prior to uninstalling a software program.

Then yes... continue on with the rest of the instructions.

 

Not good.

Are you able to run TDSSKiller?

Go to TDSSKiller and Download TDSSKiller.zip to your Desktop

• Extract its contents to your Desktop so that you have TDSSKiller.exe directly on your Desktop and not in any subfolder of the Desktop.
• Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor.
• Allow the application to run and a window will open showing that it is TDSSkiller from Kaspersky
• Click Start scan
• It will run rather quickly and will notify you of whether anything is found or not.
• Follow the instructions to delete/quarantine if asks you what to do when if finds something.

Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply. (See: HOW TO: Attach Items To Your Post )

 

Do you have your Windows XP boot CD?

Move the TDSSkiller.exe file ( or redownload it ) to your root folder so that you have C:\TDSSkiller.exe to make it much easier to run.

Then reboot your PC with your boot CD and then get into the recovery console as described below*) At the prompt window enter the below and hit enter ( it is case insensitive ):

C:\tdsskiller.exe

Hopefully it runs okay. Then reboot normally and see if things are working better of not. Attach the log from TDSSkiller if it made one in your root folder.

To run the Recovery Console from the Windows XP startup disks or the Windows XP CD-ROM, follow these steps:

 

You may want to try creating and using 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.

whistler/black internet@mbr again!

 

Looks good now.



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 oof 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:
