Hello

I am working with a computer that seems to be massively infected - pretty sure I have a rootkit infection of some kind, at the very least.

Windows XP system

I can't boot into safe mode - I get a blank blue screen when I try.
Whatever I'm infected with won't allow me to run any scans - shuts down TrendMicro, Kasperky, AVG.
It shuts down HiJackThis
It shuts down dds
It shuts down RootRepeal
Mbs.exe and b.exe run in the task manager processes. I shut them down and they restart.
I remove all startup items in msconfig and b.exe re-establishes itself at reboot.
I've been able to scan using the AVG Win/32Virut Remover. It gave me a scan result which I can attach if need be.
I have also been able to run Win32kDiag.exe and I have a logfile for that as well.

Am I beyond help?

I greatly appreciate any assistance you can offer.

Download this file and save it to your desktop:

http://download.bleepingcomputer.com/grinler/rkill.scr



Double-click the file to run it. A command window will open briefly. Then run a quick scan with Malwarebytes (see instructions below).

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

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thank you for the reply, Budapest.

Whatever virus/rootkit is on this computer won't allow .scr files to be executed.
I already had Malwarebytes installed on the system; it starts and then shuts down.

The problem has worsened at this point - it's not allowing internet access at the moment.

I appreciate your attempt to help. I was able to run one type of scan - but I am unable to upload the log file.

I will keep working at it to see if I can re-establish the internet connection.

Thanks so much!

You can try renaming the rkill.scr file to explorer.exe and then see if it will work. If so try Malwarebytes again.

If that doesn't work try this scan. You can copy it over from another computer if you need to.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Thanks again, Budapest

DrWebCureIt also shuts down after starting the application.

I am not able to access safe mode at all. It boots to a blue screen - task manager doesn't even work there.

I am sorry....every suggestion seems to run me to a dead end. I know it's frustrating but I do appreciate the assistance you've tried to offer.

Run this and then see if you can get into Safe Mode:

Budapest -

No, it did not allow me to access safe mode after running that either.
I am really sorry - it seems things go from bad to worse.

I apologize...I am unable to access the internet. It's not recognizing my network adapters.

It also isn't allowing me to cut and paste.

What happens when you try to cut and paste?

It appears to allow the copy function....but paste is "greyed out". Control V doesn't work either.

The day I started having issues, I was able to run a Win32kDiag scan....can't paste it.

I think the past three days have allowed whatever the heck this is to really settle into my system. It is distressing.

Are you able to copy the http://live.sunbeltsoftware.com/ scan over from another computer?

Sorry, Budapest - I've got my MORON hat on today. Trying that now.

Note to self - Don't make Budapest think you're an idiot that doesn't belong on the internet which is why you've been smote with the plague virus.
