My hosts process crashes every so often in different occurrences as well. Also, IE seems to be hijacked, the number of IE processes seems to be increasing. Infected files are suspected to be hki1596.exe and yTU2dHec.exe as of now and I believe svchost.exe might be infected as well by Bamital.

A previous eset scan provided as this infection started:
C:\Users\Public\Documents\Server\hlp.dat Win32/Bamital.EK trojan cleaned by deleting (after the next restart) - quarantined
C:\Windows\explorer.exe Win32/Bamital.EL trojan unable to clean
C:\Windows\System32\wininit.exe Win32/Bamital.EL trojan unable to clean
Operating memory Win32/Bamital.EL trojan

However, the recent scans don't show any of these anymore.

Unable to scan using GMER since it keeps saying that the program crashes.

Edit: Was able to copy a partial scan before GMER crashed.

EDIT: Posts merged ~BP

Hello and welcome to Bleeping Computer

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.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.

Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination 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 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

Similarly to my first post, unable to scan with gmer after it reaches the devices part of the scan. Gmer would just crash. Was only able to copy the available scan before it crashed.

Applications of Windows Explorer would usually lag up and become unresponsive at times, while switching to other programs works fine.

Here are my updated logs.

Hi there, my apologies for the delay. Lets start with the cleaning here. :)

COMBOFIX
---------------
Please download ComboFix from one of these locations:
Bleepingcomputer
ForoSpyware
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and 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: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.

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.

regards, Elise

Currently, I am running in safe mode with networking as I cannot start Windows properly without it crashing after the vista screen loads.

But here is the combofix log.

Unfortunately you had a nasty rootkit on your computer. It is gone now, but please read the following information.

BACKDOOR WARNING
------------------------------
One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and cleaned, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

Please let me know if you can boot now in Normal mode and if not, if you have a Vista DVD at hand.

regards, Elise

I still cannot boot into Normal mode and as of the moment, I do not have my boot disc handy. Upon further observing the crash, I recognized the stop code as STOP: 0x0000008E. Not sure if this helps in any way.

At which point exactly does the BSOD occur?

Do you have a Vista DVD at hand?

If so, please perform a Startup Repair

No, unfortunately, I do not. However, I am capable of burning my own recovery disc.

Yes, however, I am not sure this will work. Not all Recovery disks will have the option to perform a startup repair.

You can also tap F8 on start up and see if the option to Repair Windows is present in the Advanced Boot options menu.

regards, Elise

Startup repair indicated my OS was able to boot properly without any errors, but when I tried running in normal mode again, the stop error still occurred.
