  • Select the Windows folder of the infected drive if it asks for a location.
  • When asked Do you wish to load the remote registry, select Yes.
  • When asked Do you wish to load remote user profile(s) for scanning, select Yes.
  • Ensure the box Automatically Load All Remaining Users is checked and press OK.

  • Copy this file to a USB drive if you do not have internet connection on the system.
  • Please attach the content of OTL.txt in your next reply.
 
Thank you for your response. I was able to create the CD but am unable to get the system to boot from CD Rom. I followed the instruction and was able to select boot from CD but it gives me a failure and then proceeds to boot from HD. I suspect that my CD drive is bad as it was giving me issues before. I am also unable to do a safe boot as when the computer starts booting up and I press F8 to go in it locks me out and goes straight to HD regular bootup. I did notice that I am able to log in and use the other 2 users set up on the computer and I can even go online with them with no problem. I also tried to do a boot from USB after creating a bootable USB with the anti-malware program but it is not working either.
Is there another way to gain safe mode entry?
 
Ok go on the clean user account and do the following in either one of them.

Download OTL by Old Timer from here and save it to your Desktop.
  • Double click on OTL.exe to run it.
  • Click the Scan All Users checkbox.
  • Check the boxes beside LOP Check and Purity Check
  • Click on Run Scan at the top left hand corner.
  • When done, two Notepad files will open.
    • OTL.txt <-- Will be opened
    • Extra.txt <-- Will be minimized
  • Please attach the contents of these 2 Notepad files in your next reply.

If you don't know how to attach the files, please follow the instructions here: http://malwaretips.com/Thread-How-to-use-the-attachment-system?pid=16072#pid16072
 
Excellent :D

Before we start:
  • Note that the removal process is not immediate. Depending on the severity of your infection, it could take a long time.
  • Malware removal can be dangerous. I cannot guarantee the safety of your system as malware can be unpredictable. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system. Therefore, I would advise you to backup all your important files before we start.
  • Please be patient and stay with me until I give you the green lights and inform you that your PC is clean.
  • Some tools may be flagged by your antivirus as harmful. Rest assure that ALL the tools we use are safe, the detections are false positives.
  • The absence of symptoms does not mean your PC is fully disinfected.
  • If you are unclear about the instructions, please stop and ask. Following the steps in the order that I post them in is vital.
  • Lastly, if you have requested help on other sites, that will delay and hinder the removal process. Please only stick to one site.


Go back to the account you ran OTL. Open OTL and under custom scan/fixes, copy and paste the following:

:OTL

Thanks for the update. I went ahead and ran OTL with the new fix, rebooted and opened the infected user account but it still went directly to the virus screen. Still cannot enter in safe mode either.
 
The other accounts do not have admin access. I downloaded and ran the TDSSKiller, when I selected the loaded modules and went to reboot i received an error message saying that "can't install extended monitoring driver" and then it does not allow for either a reboot or a scan.
 
Download avenger.zip... © by Swandog46
  1. Unzip/extract it to a folder on your desktop.
  2. Double click on avenger.exe to run it. Click "OK"...at the prompt.
  3. Check the box... "Scan for rootkits"
  4. Uncheck the box... "Automatically disable any rootkits found"...if checked.
  5. Copy all of the text in the code box below and paste it in the box "input script here"Ctrl+C.
    Code: 
    Files to delete:
C:\Documents and Settings\All Users\Application Data\-lcrulcmPDdr
C:\Documents and Settings\All Users\Application Data\-lcrulcmPDd
C:\Documents and Settings\All Users\Application Data\lcrulcmPDd
C:\Documents and Settings\All Users\Application Data\lcrulcmPDd.exe
C:\Documents and Settings\All Users\Application Data\gla.pad
  6. Click the Execute button.
  7. Reply "Yes" at the 2 prompts:
    "Are you sure you want to execute the current script?".
    "First step completed --- The Avenger has been successfully set up to run on next boot. Reboot now?".
  8. Your PC will automatically reboot.
    If that is the case, it will force a BSOD (Blue Screen of Death) error ...on the first reboot. This is normal & expected behavior.
  9. After your PC has completed the necessary reboots, a log should automatically open.
    If it does not automatically open, then the log can be found at %systemdrive%\avenger.txt (typically C:\avenger.txt).
 
OK, just ran the avenger and when i click execute and press yes for the first prompt "are you sure you want to execute the current script?" I get the following error:
Error: Can't open file 'C:\Program Files\tcdaaluk.txt' (error 5: access is denied)
When I click OK to this message I get the following:
Error: Could not open script file: Aborting Execution! (Error 6: the handle is invalid.)
 
Do you have recovery console installed on the machine?

If not, do you have the XP CD? If so, http://support.microsoft.com/kb/307654

Also, are you able to enter safe mode if command prompt?
 
For recovery console, reboot your PC. As soon as it starts, do you see a screen like this?

For safe mode with command prompt, reboot your PC and keep tapping the F8 key until you reach the Advance boot option page. Use the arrow keys to select safe mode with command prompt
 and press enter.

when i reboot the pc and press F8 I don't go into advance boot option, it locks me out and then reboots normally. For recovery console i have never seen that screen before.
 
Ok, let's give this a try.

ok i was finally able to do this and it seems to have worked. i ran both Malwarebytes and Hitman Pro after the last restart to scan and came back all clean.
Thank you so much for all your assistance.
