Attempting to assist a friend with system trashed by viruses/malware. Some success, but not complete

Windows XP Media Edition SP3 on Dell Dimension E510

- System freezing at various points during boot and during use
- Windows Defender scan reports clean
- Trend Micro Housecall online scan reports clean
- Ad-Adware AE repeatedly reports Win32Backdoor.TDSS found. Same 2 files always removed then reappear:
(toggled System Restore off/on, no help)
- Spybot 1.6.0 installs, but fails to present GUI when started
- HijackThis install (HJTInstall.exe) fails
- Malwarebytes' Anti-Malware install fails
- SDFix install fails
- Smitfraud Fix install fails
- Avanquest Fix-It Utilities 9 installed, then uninstall failed

I do not have user's O/S install disks.

Advice is greatly appreciated

More info...

When shelling to DOS, the doing a DIR to list the offending TDSS dlls, the following appears:

[codebox]C:\WINDOWS\system32>dir TDSS* /s
Volume in drive C has no label.
Volume Serial Number is 6035-DD19

Directory of C:\WINDOWS\system32

The parameter is incorrect.
12:00 AM 0
The parameter is incorrect.
12:00 AM 0
2 File(s) 0 bytes

Directory of C:\WINDOWS\system32\drivers

The parameter is incorrect.
?↕??< 0
1 File(s) 0 bytes

Total Files Listed:
3 File(s) 0 bytes[/codebox]

I suspect this is why AdAware can't really clean these two files.

CHKDSK also reports an issue, but CHKDSK /F doesn't run at start-up. It won't run from AUTOEXEC.BAT either:

The type of the file system is NTFS.

WARNING! F parameter not specified.
Running CHKDSK in read-only mode.

CHKDSK is verifying files (stage 1 of 3)...
File verification completed.
CHKDSK is verifying indexes (stage 2 of 3)...
Deleting index entry sessionstore.js in index $I30 of file 62959.
Deleting index entry SESSIO~1.JS in index $I30 of file 62959.
Index verification completed.

Errors found. CHKDSK cannot continue in read-only mode.[/codebox]

Also SFC /scannnow wants to replace files, but I have no SP3 CD. I do have a clean SP3 system. I'm going to try and bring over a copy of /system32/dllcache from it to affect some repairs.

(Edit 1/31/2009)
I was able to scare up an old Windows XP Pro SP1a install disk. I booted with it into Recovery Console, and was able to easily delete the nasty TDSS files, which were:


There was also some TDSS file with a 'log' extension which I deleted as well.

Immediately upon rebooting, the scheduled CHKDSK ran successfully, and the system booted without freezing. Ad-Aware is no longer reporting Win32Backddor.TDSS. I believe the problem is solved, but will post back any other discoveries from here.

Howdy, my name is Hoov, and I will be helping you with your dilemma.

Please make sure you watch this thread for responses. If you click the options tab at the top of your first post, you can select to track this thread.

Here is what I am asking you to do during the repair of your computer

*Tell me everything that you have done, if anything, to try and fix this problem.

*Please only use 1 forum to help clear up your problem. Posting on more than 1 and following instructions from more than 1 forum will cause those helping you to pull out thier hair.

*Follow my instructions - If you can't for some reason, or if you don't understand something, please tell me. If you deviate from my instructions, tell me, it may make a difference on where we go. Don't install anything, even other programs that have nothing to do with security or malware, it could cause things to change, and I would never know it.

*Have faith. I will do all I can to get your computer working, and if I can't - someone else here will know something else to try.

*Stick with me to the end. My aim is to fix your problems, and give you the tools and knowledge to keep this from happening again.

Now onto trying to fix your computer.

If I am helping you and you don't hear from me for 24Hrs, send me a PM Please!

  • 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Run ComboFix.exe. Please visit this webpage for download links, and instructions for running the tool:


* Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix. Also make sure you close all your browsers just before the instructions tell you to start the scanner.

Please include the C:\ComboFix.txt in your next reply for further review.

Do not mouseclick combofix's window while it's running. That may cause it to stall
