Hello and welcome.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.

• Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
  Vista/Windows 7 users right-click and select Run As Administrator.
  
• If TDSSKiller does not run, try renaming it.
  
• To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  
• Click the Start Scan button.
  
• Do not use the computer during the scan
  
• If the scan completes with nothing found, click Close to exit.
  
• If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  
• Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  
• A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  
• Copy and paste the contents of that file in your next reply.

Next run ATF:
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Please download ATF Cleaner by Atribune & save it to your desktop.

• Double-click ATF-Cleaner.exe to run the program.
  
• Under Main "Select Files to Delete" choose: Select All.
  
• Click the Empty Selected button.
  
• If you use Firefox browser click Firefox at the top and choose: Select All
  
• Click the Empty Selected button.
  If you would like to keep your saved passwords, please click No at the prompt.
  
• If you use Opera browser click Opera at the top and choose: Select All
  
• Click the Empty Selected button.
  If you would like to keep your saved passwords, please click No at the prompt.
  
• Click Exit on the Main menu to close the program.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.

Download Link 1
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.
  For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  
• 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.

Troubleshoot Malwarebytes' Anti-Malware


Please post back the TDDS and MBAM logs and tell me how it's running now.

Hello Boopme,

Thanks for your tips to remove the TDSS virus.

However, after downloading and executing the TDSSKiller.exe; i get the first window saying:

"Cant initialise log"

When I try to close the above window; then the 2nd window is:

Subsequently, the exe file closes and whole process stops there itself.

Please advise what to do at this stage.

Thanks

Ok, let's skip over Defogger and try running the scan tools above.

Thanks.

I have tried running the TDSS killer.exe again. However, we again get stuck with "cant initialize log" and error "cant load driver".

I think we are stuck. Need your help.

Look forward to your reply.

Hmmm,try
Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

"%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v



If it says Hidden service detected DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file. When it is done, a log file should be created on your C: drive called "TDSSKiller.txt" please copy and paste the contents of that file here.
