Posted 26 October 2011 - 09:46 AM

Thank you in advance, I work in IT and this is a corporate machine typically I usually just format / reinstall but I have been wanting to learn the 'art' of virus removal. I have used bleepingcomputer as a google resource for years and this is my first time posting. A big thanks to all of you for all the help you have indirectly given me in the past.

I have already ran combofix as that is what I am familar with. It detected rootkit.zero access and did its best to remove it. upon reboot I ran TDSKiller which found
C:\WINDOWS\system32\DRIVERS\netbt.sys - will be cured on reboot
09:46:52.0498 3120 NetBT ( Rootkit.Win32.ZAccess.g ) - User select action: Cure

At this point everything seemed good, I could again browse \\network\ resources. However after about 20 minutes of use I can again no longer browse \\items\ (shared folders/mapped drives)

I would really appreciate a walkthrough. Thanks to all you guys have done.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

Posted Image In order to continue receiving help at BleepingComputer.com, YOU MUST tell me if you still need help or if your issue has already been resolved on your own or through another resource! To tell me this, please click on the following link and follow the instructions there.

CLICK THIS LINK >>> http://www.bleepingcomputer.com/logreply/425094 <<< CLICK THIS LINK



If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.
===

Download http://public.avast.com/~gmerek/aswMBR.exe (aswMBR.exe) ( 511KB ) to your desktop. Double click the aswMBR.exe to run it

  • Click the "Scan" button to start scan.
  • Upon completion of the scan, click Save log, and save it to your desktop. (Note - do not select any Fix at this time) <- IMPORTANT
  • Please post the contents of that log in your next reply.
There shall also be a file on your desktop named MBR.dat. Right click that file and select Send To>Compressed (zipped) folder. Please attach that zipped file in your next reply.
===

Please download ComboFix from one of these locations:

Link 1
Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

  • Disable your Anti-Virus and Anti-Spyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
  • 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.
  • Some Rookit infection may damage your boot sector. The Windows Recovery Console may be needed to restore it. Do not bypass this installation. You may regret it.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Posted Image


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

Posted Image

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Note: If you have difficulty properly disabling your protection programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html

Do not mouse click ComboFix's window while it's running. That may cause it to stall
===

Third party programs if not up to date can be the cause infiltration of an infection.

Please run this security check for my review.

Download Security Check by screen317 from here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.
===

Please post the logs and let me know if the problem persists.

Thank you so much for your help, attached is the logs.
While combofix was running I got a couple of DEP warnings so it looks like the main explorer.exe is infected


Also you know how I would go about seeking entry into the training program?

Open notepad and copy/paste the text in the quote box below into it:

ClearJavaCache::



Save this as CFScript on your desktop.

Referring to the picture above, drag CFScript into ComboFix.exe
Then post the resultant log.

Secure your system by updating 3rd party programs.

Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.
Updating Java:
  • Download the latest version of Java SE Runtime Environment 6 Update 27.
  • In the box labeled "Java Platform, Standard Edition", click the "Download JRE" button to the right.
  • In the Window that opens, select Windows (or Windows x64), and check the "agree" box and click "Continue".
  • Click on the link to download Windows Offline Installation and save to your Desktop.
  • Then from your Desktop double-click on jre-6u27-windows-i586.exe that you have downloaded to install the newest version.

    For the x64 bit version download this on jre-6u27-windows-x64.exe). Make sure you download the corrent version.

    - Note: If you are running Vista or Windows 7, you may need to right-click on the installation file and select Run as Administrator.

If present remove the old version(s) of Java using the Add/Remove Programs applet.


Java™ 6 Update 5

===

Also you know how I would go about seeking entry into the training program?

Follow the instructions here.

http://www.bleepingcomputer.com/forums/topic174633.html

When ready post that you have read the instructions and are ready to start your training.

Sorry, an error occurred. If you are unsure on how to use a feature, or don't know why you got this error message, try looking through the help files for more information.

[#10342] We could not determine which forum this topic is in. "


I contacted the owner of the topic. I will keep you posted.

Are you still having problems with this computer?

It does look like we are still having issues. Odd problems at various times with network access. Internet works but anything on domain like shared folders or SQL connections does not work.

Launch Notepad, and copy/paste all the blue instructions below to it.
Save in: Desktop
File Name: fixme.reg
Save as Type: All files
Click: Save

REGEDIT4
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

[-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\EscDomains]
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\EscDomains]


Then, disconnect from the Internet!
Next,
Back on the Desktop, double-click on the fixme.reg file you just saved and click on Yes when asked to merge the information.

On a Vista or Windows 7 operating system right click on the fixme.reg file and run as Administrator.

Optional if the following programs are in your computer.
Note that since the Domains are deleted SpywareBlaster protection must be re-enabled. Spybot's Immunize feature must be used again, also you have to re-install IE-SpyAd if installed.

Not sure if this article will help.

You might find other solutions by searching Google for this string dropping domain connections randomly

These tools are no longer needed.

Time for some housekeeping

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following bold text into the Run box and click OK:

ComboFix /Uninstall

Delete the other tools we used.
