This problem started about a week ago when I was researching to repair another PC (unrelated). I am running Vista Business BTW. I was notified by my Symantec Endpoint Protection that something tried to infect my computer, i didn't feel that Symantc handled the problem and the computer was acting funny so I shutdown and booted into Safe Mode. Tried to run a scan with Symantec and noticed it was malfunctioning, so I updated and ran a scan with MBAM and it only found some Tracking Cookies, so it wanted to restart when the scan was complete, so I let it reboot. On reboot I got the windows screen with the progress bar at the bottom and then went to a black screen with a cursor taht i could move about the screen, I tried to do a Ctrl-Alt-Delete and nothing happened, I tried hitting Shift 5 times and I heard a chirp noise but thats it. the HDD light stopped flashing and no more progress. However Safe Mode still works, so I updated and ran MBAM, Spybot S&D, SuperAntiSpyware, and ComboFix. Sometimes the sans would complete, other times the scans would lockup the computer.

I am getting a message from my Visual Studio Just In Time Debugger thet "An unhandled win32 exception occurred in explorer.exe [1984]" and when I use the debugger the line in the assembly code where the error occurs is "75B6CF8A mov dword ptr [edx], ecx" the values for edx=00001388 and ecx-00000000.

DDS will run and create a log but RootRepeal will not complete a scan of the file system it ALWAYS stops at c:\users\justen.000\AppData\Local\Opera\Opera\cache however this directory is empty. So I ran RootRepeal with everything checked except Files, and then did another scan with just files checked and stopped the scan before it reached the aforementioned directory.

I tried to run rkill but when I run it the screen refreshes and brings up the Windows Help and Support about safe mode box and refreshes the explorer.exe error. And the previous scans did not behave any differently.

one result that I found interesting was MBAM found c:\Combofix\pv.cfxxe and c:\ComboFix\pv.com and another in the ComboFix Directory but cant remember the name. I did some searches on this and found others talking about a file c:\32788R22FWJFW so I looked and found a directory on my computer of C:\32788R22FWJFW\EN-US\cmd.cfxxe.mui other than the EN-US directory c:\32788R22FWJFW is empty. I installed ComboFix on this computer and noticed that ComboFix uses this directory but their are more files in it. On my infected computed the only directory that has something in it is C:\32788R22FWJFW\EN-US\cmd.cfxxe.mui

Hope this information is useful.

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



Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.
regards,
schrauber

Hello, jcastle482
Welcome to the Bleeping Computer Forums. My name is Thomas (Tom is fine), and I will be helping you fixing your problems.

If you do not make a reply in 5 days, we will have to close your topic.

You may want to keep the link to this topic in your favourites. Alternatively, you can click the button at the top bar of this topic and Track this Topic. The topics you are tracking can be found here.

Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools. Doing so could cause changes to the directions I have to give you and prolong the time required. Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean". We do not want to clean you part-way, only to have the system re-infect itself.
  • Please reply using the button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Old topics are closed after 3 days with no reply, and working topics are closed after 5 days. If for any reason you cannot complete instructions within that time, that's fine, just post back here so that we know you're still here.
  • Please set your system to show all files.
    Click Start, open My Computer, select the Tools menu and click Folder Options.
    Select the View Tab. Under the Hidden files and folders heading, select Show hidden files and folders.
    Uncheck: Hide file extensions for known file types
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.





Please go here and have a look how you can disable your security software.

Download Combofix from any of the links below but rename it to before saving it to your desktop.

Link 1
Link 2



--------------------------------------------------------------------

Double click on the renamed Combofix.exe & follow the prompts.
    When finished, it will produce a report for you.
  • 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, ComboFix will continue it's malware removal procedures.



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



Click on Yes, to continue scanning for malware.

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

This tool is not a toy and not for everyday use.
ComboFix SHOULD NOT be used unless requested by a forum helper

Tried running the renamed combofix from the desktop however it stops after it backs up the registry. The c prompt is still up and says Please wait. ComboFix is preparing to run. Checked the task manager and it is not using processing cycles.

Hi,

  • Download TDSSKiller and save it to your Desktop.
  • Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.
  • Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

  • If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
  • When it is done, a log file should be created on your C: drive called "TDSSKiller.txt" please copy and paste the contents of that file here.

regards,
schrauber

Here is the log created by the commands from the run dialogue box. I am now attempting to copy the new atapi.sys fom the DVD as instructed above.

Volume in drive C is SQ004013P03
Volume Serial Number is 30A4-D421

Directory of C:\

01/19/2008 12:06 AM 21,560 atapi.sys
1 File(s) 21,560 bytes
0 Dir(s) 137,275,138,048 bytes free

------------------------------------------------------------

Update:
I got the system restarted to Safe Mode, it is set to Safe Mode by default because it wasn't booting otherwise. Not getting the error with explorer.exe anymore. Should I try booting normally?
