Hi Folks
I have been fighting an infection on a WIN XP SP3 computer for a while now.

I have spent the last 4 days trying to research all the possible solutions, but this one is resisting like nothing I have ever seen before.

It seems to be TDSS related and only lets me do certain things before locking up or just not running what I want to run.

I was able to get Malwarebytes Antimalware to run once. I was able to run SDFix once also. they both took care of some things as well as the Verizon DSL security Suite that runs on this machine.

It seems to be trying to load a dll called TDSScfum.dll. Even just trying to start notepad I got an error message
-->notepad.exe - Bad image
X The application or DLL globalroot\systemroot\system32\TDSScfum.dll is not a valid windows image. Please check this agains your installation diskette.

I am trying to repair this for some people and they have 4 separate logon IDs with separate data folders. Because of all the different programs and data stores I am trying to clean this without a full reformat.

Thanks for any help you may be able to provide

John

Thanks Budapest for a quick response.

I did get ATF cleaner to run.

The bugs have taken over so much of the friends computer that I can't get hijack this to install or SuperAntiSpyware.
I can't as far as I can see get most other things to install.

Can anyone think of some registry tweaks to look for? I think I can still get regedit running.

Thanks John

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 DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

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 drweb-cureit.exe 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.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now 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 Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "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)

Me again
I am still watching the Dr Web Cure full scan, but find it interesting that it looks like some of the Combo-Fix desktop items are now being seen as infected by Dr Web Cure. That probably explains why some of the programs I thought I was putting on the desktop to run failed.

I am still not sure what happened to the Malwarebytes Antimalware that ran once. It seems that this bug has all kinds of hooks on executables.

I sure hope someone soon can create a one stop solution for this one! I don't want to see it again!

I wouldn't worry about the ComboFix things. The way ComboFix works, many other scanners report it as being malware. This is what's know as a false positive.

ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer.

Thanks again
I believe this monster is Slain!

I am negligent in not saving the Dr Web csv, but all seems well and I will post a final assessment after some more tests and some sleep.
