Pleas help...

Running XP Home Edition on Dell Dimension 9150. Got a Trojan.Fake virus (I think based on anti-malware report). Things got better, then a lot worse. Can't get past BSOD in any start up mode (Safe mode, etc).

BSOD message is: 0X0000007E (0xC0000005, 0x8050D532, 0XF789E508, 0XF789E204)

I've removed the hard drive, installed into an external enclosure so I can troubleshoot and hopefully fix it. Ran Malware Bytes and SuperAntispyware. Also ran Registry Mechanic. None has fixed the BSOD.

Last problem: I don't have the original XP installation disk.

Thanks in advance for any advice...

Stay away from any registry tools!

Did the programs detected anything?
Do you still have the drive in the enclosure?
 
Thanks for the response.

OK, I'll stay away from Reg programs (including regedit??). Programs detected alot. I attached the log files from SuperAntiSpyware and MalwareBytes Anti-Malware.

Yes, I still have the drive in the enclosure.
 
Yeah. Sorry about that. Here they are:

Please download ComboFix from Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
  1. Please, never rename Combofix unless instructed.
  2. Close any open browsers.
  3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
    • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
    NOTE1. If Combofix asks you to install Recovery Console, please allow it.
    NOTE 2. If Combofix asks you to update the program, always do so.
    • Close any open browsers.
    • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
    • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
    • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
  4. Double click on combofix.exe & follow the prompts.
  5. When finished, it will produce a report for you.
  6. Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review.
**Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

Make sure, you re-enable your security programs, when you're done with Combofix.

DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!
 
Broni, Thank you for your help. I have one point of clarification: ComboFix will be installed and run from my laptop and will point to the external drive that is the affected computer, right? Since I can not download to my affected computer as it has BSOD.
Thanks
 
Ran ComboFix.exe then re-ran Anti-Malware. Uploaded both log files but they don't appear to have scanned the E: drive. Should I re-install the hard drive into the troulbled computer?

Thanks again for your help.

Not yet.
I'm pretty sure, E drive has been scanned, but apparently nothing has been found.

Go to Kaspersky website and perform an online antivirus scan.

1. Disable your active antivirus program.
2. Read through the requirements and privacy statement and click on Accept button.
3. It will start downloading and installing the scanner and virus definitions. You will be prompted to install an application from Kaspersky. Click Run.
4. When the downloads have finished, click on Settings.
5. Make sure these boxes are checked (ticked). If they are not, please tick them and click on the Save button:

  • Spyware, Adware, Dialers, and other potentially dangerous programs
    [*] Archives
    [*] Mail databases
6. Click on My Computer under Scan.
7. Once the scan is complete, it will display the results. Click on View Scan Report.
8. You will see a list of infected items there. Click on Save Report As....
9. Save this report to a convenient place. Change the Files of type to Text file (.txt) before clicking on the Save button. Then post it here.

Post fresh HijackThis log as well.
 
Broni, I ran Kaspersky last night and have attached the log file. Also installed and ran HighJackThis. Looks like the E drive had some problems.

Did you remove those files manually by any chance?
If not, can you check through Windows Explorer, if those files are there.

==================================================================

Your E drive is infected with TDSS rootkit. That's why you can't boot.

1. Please download The Avenger to your Desktop.
  • Right click on the Avenger.zip folder and select "Extract All..."
  • Follow the prompts and extract the Avenger folder to your desktop
2. Copy all the text contained in the code box below to your Clipboard by highlighting it and pressing (Ctrl+C):


Code: 
Begin copying here:
Files to move:
C:\WINDOWS\system32\drivers\iaStor.sys | E:\WINDOWS\system32\drivers\iaStor.sys


3. Now, open the avenger folder and start The Avenger program by clicking on its icon.

  • Right click on the window under Input script here:, and select Paste.
  • You can also click on this window and press (Ctrl+V) to paste the contents of the clipboard.
  • Click on Execute
  • Answer "Yes" twice when prompted.
4. The Avenger will automatically do the following:

  • It will Restart your computer. ( In cases where the code to execute contains "Drivers to Delete", The Avenger will actually restart your system twice.)
  • On reboot, it will briefly open a black command windowon your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
  • The Avenger will also back up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.
5. Please copy/paste the content of c:\avenger.txt into your reply
 
I reran the OTM program and uploaded the log file. For some reason, I lost communication with the USB external drive. I turned it off/on and re-established communication before running OTM.

I then ran avenger and the syste rebooted bu the log file says:

No rootkits found!

Error: file move operations must be within volumes.
File move operation "C:\WINDOWS\system32\drivers\iaStor.sys|E:\WINDOWS\system32\drivers\iaStor.sys" failed!
Status: 0xc000003e (STATUS_DATA_ERROR)

Maybe it worked anyway...

OTM - good.

Now, you'll have to do something manually.
Go to C:\WINDOWS\system32\drivers and copy iaStor.sys file.
Now, go to E:\WINDOWS\system32\drivers rename iaStor.sys file to iaStor.old and paste iaStor.sys file, you just copied from C drive to E:\WINDOWS\system32\drivers folder.
 
Broni - you are the man. I'm back up & running. Thanks for all of your expertise. Any final words of advice or warning?
 
Excellent!
Yes, we need to rescan to make sure, you're safe.

Print these instructions out.

NOTE. If any of the programs listed below refuse to run, try renaming executive file to something else; for instance, rename hijackthis.exe to scanner.exe

***VERY IMPORTANT! Make sure, you update Malwarebytes before running the scans.***


STEP 1. Download Malwarebytes' Anti-Malware: http://www.malwarebytes.org/mbam.php to your desktop.
(Malwarebytes is free to use as a manual scanner. Payment is only required if you wish to have it run and update automatically which is not necessary for our purposes)

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Quick Scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

RESTART COMPUTER!

STEP 2. Download GMER: http://www.gmer.net/files.php, by clicking on Download EXE button.
Alternative downloads:
- http://majorgeeks.com/GMER_d5198.html
- http://www.softpedia.com/get/Interne...ers/GMER.shtml
Double click on downloaded .exe file, select Rootkit tab and click the Scan button.
When scan is completed, click Save button, and save the results as gmer.log
Warning ! Please, do not select the "Show all" checkbox during the scan.
Post the log to your next reply.

RESTART COMPUTER

STEP 3. Download HijackThis:
http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis/download
by clicking on Installer under Version 2.0.2
[DO NOT download version 2.0.3 (beta)]
Install, and run it.
Post HijackThis log.
NOTE. If you're using Vista, or 7, right click on HijackThis, and click Run as Administrator
Do NOT attempt to "fix" anything!


DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!
 
Step 1 : All good.
Step 2 : GMER got hung up and BSOD appeared:

pfddikob.sys

stop: 0x00000050 (0xE57F5000, Ox00000000, 0XA2BBCC3E, 0X00000001)

BSOD is still up on screen
 
Step 1 : All good.
Click to expand...
Nothing detected?

Leave GMER alone, reboot manually.

OK, back up & running. Here are the log files. By the way, spybot asks to accept or deny registry changes after ComboFix runs. This last time around, I denied ctfmon.exe but then allowed everything else. Should I be denying or accepting these requests?
