Hello, i got infected with several different trojans last week. I have downloaded several anti virus, spyware, malware etc but i can't get rid of this pest. I got the virus that asked me to buy fake antivirus and hid all my files. I was able to get rid of it and unhide my files. I am also being redirected when i do google searches and my audio played random commercials. I deleted the audio driver, i have no audio now. And the virus author left me a note on the desktop named "catchme" and it said ".. volsnap sys succesfully installed"
i can't run tdsskiller, i have tried renaming it too-- but still nothing. I have AVG, Avast, malware bytes, PCtools, downloaded combofix but have not run it yet. So i'd appreciate your help.

I had this same virus on 3 PCs last week. Here's what you need to do.

Download a program called Resource Tuner (www.restuner.com). There's a 30-day free trial that will do the trick.

Resource Tuner will allow you to change all of the naming information within TDSSKiller. I used this program to change anything that said TDSS or Kapersky to "Game" or "Test". Changing all of that information then allowed TDSSKiller to run and remove the virus.

Hope this helps! That was a rather nasty virus.

Looks like you might have a Rootkit

Follow this guide by boopme

Hello,lets first see if there is a malware here.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.5.0.0) 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.


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 these[/color] instructions. In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.

Be sure to download TDSSKiller.exe (v2.5.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.

That part of the instructions is outdated so disregard. I updated them a while back to remove that sentence since it no longer applies. The current version of TDSSKiller is v2.5.4.0 and both .zip and .exe files should be the same.

I'm fighting this virus, too. I cleaned it from a customer system twice, only to have it come back twice. Each time is changed all of the file attributes on the hard drive to "Hidden". It now has come back a third time. This time it used a different methodology, but didn't hide all of the files. All three infections used an infected volsnap.sys file.

I have no trouble getting rid of the pest and fixing the damage, but I can't figure out how it is re-infecting. Any insights out there? Please?

An infected volsnap.sys is a new variant of the TDSS rootkit.

To learn more about this malware and it's history, please refer to:These are .pdf documents with more comprehensive information.
If you need assistance, please start your own topic. Doing that will help to avoid the confusion that often occurs when trying to help two or more members at the same time in the same thread. Even if your problem is similar to the original poster's problem, the solution could be different based on the kind of hardware, software, system requirements, etc. you are using and the presence of other malware. Further, posting for assistance in someone else's topic is not considered proper forum etiquette.

Thanks for your cooperation.
