Windows defender, norton antivirus, malwarebytes and a-squared anti-malware detects this virus in my c:\windows\system32 folder as the filename tdlcmd.dll and removes it from the system, but after restarting the computer it comes back again.
I tried to delete it in safe mode too, but it won't work.
I was going to try the Combofix tool, but i read that i shall NOT RUN IT ON VISTA, WARNING WARNING.

I'm using Vista home premium.

Could somebody please be so kind and help me to get rid of this terrible virus ?
In advance, thx ! :thumbsup:

I'm sorry to add so many replies, but i guess nobody can or wants to help me tonight ?
I see almost all topics got a reply, but mine haven't got 1 reply yet and i've been waiting for almost 5 hours now.
All i'm asking for is just 1 reply, and it doesn't matter if i get help or not.
If you can't help me with the problem i just hope you can tell me so i don't have to sit and wait for so long.
Don't misunderstand me pls, because i understand that this virus is a bit tricky to fix.
If you are too busy to help me now, but you can help me later i hope you can tell me that too.
Then i come back later to see if you could help me.
Thx

Ps: I would just like to add that this is my first topic on this forum.
I just registered so i don't know all your procedures for asking etc... !

Try This First! :

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to abcdefg.exe instead of mbam-setup.exe

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.

Double Click abcdefg.exe to install the application.
* Make 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 Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Hi, thx for the reply ! :thumbsup:

I tried malwarebytes anti-malware, and it found the virus.
When i tried to delete it, the program said it had to restart the computer to be able to delete it completly.
When the computer restarted i hurry myself and go to system32 folder to look for the file and it seems like it's gone, but after 30-40 seconds it suddenly comes back again.
When i run the anti-malware it detects it once more.
It won't go away ?
I tried to uninstall some programs i installed lately, but it didnt help. :flowers:

Update mbam and run a FULL scan
Please post the results

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

:flowers:
SAS, may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
    First
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 SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

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

:thumbsup:

Ok, i tried to do the MBAM yesterday, but it took too long so i didn't have time to post the result, but now i have time to post it.
I did a full system scan and this is what the log looked like :
PS: I hope you understand the text below, as the version of MBAM i'm using is Norwegian ?
If you don't understand it i can rescan using the english version, but it will take me 3 more hours i think.
I didn't think of this when i did the scan, sorry !
Ps 2 : I can try to translate, it's not perfect, but i think it's worth a try.

Ok, now my Superantispyware has finished scanning my computer in SAFE MODE.

Ps: After the scanning was finished and i had to restart my computer, then my computer got the blue screen of death just as the desktop screen was going to show itself.
I restarted my computer and i got the same blue screen of death every time on exactly the same spot and it seemed like my computer was into some kind of a loop ?
I restarted my computer 5 times and the same thing happened all times.

However, i think i managed to find out a fix or a workaround to it.
I went into safe mode again and unchecked the box in the preferences of the superantispyware "Start superantispyware when windows start".
After i unchecked that box, my computer started without the blue screen of death.
So now i finally managed to get into my internet again so i can post the log.

Both MBAM and SUPERANTISPYWARE removed some viruses/spyware, but the virus in the file "tdlcmd.dll" doesn't seem to go away.
It is still coming back.
I will try the rootkit tool now.

However, here is the LOG file for my superantispyware :

(Rootkit.TDSS) -> No action taken.
Not a very good sign

You still need to run Root Repeal, :thumbsup: from my first post, #7

Also:

Please download Win32kDiag.exe by AD and save it to your desktop.
alternate download 1
alternate download 2
  • This tool will create a diagnostic report
  • Double-click on Win32kDiag.exe to run and let it finish.
  • When it states Finished! Press any key to exit..., press any key on your keyboard to close the program.
  • A file called Win32kDiag.txt should be created on your Desktop.
  • Open that file in Notepad and copy/paste the entire contents (from Starting up... to Finished! Press any key to exit...) in your next reply.


PS: I hope you understand the text below, as the version of MBAM i'm using is Norwegian ?


We have a few members from the Netherlands I can get to help

Root Repeal just freezes.
I let it run for 6 hours now, but it seem stuck ?

I'm not sure if Win32kDiag.exe is working either.
I let it stay on for 1 hour now, but it say only this :

I read that several rootkit viruses can be deactivated by using the command prompt /fixmbr in the recovery consule before i use a antivirus tool to remove the remains.
Do you think this can be done with this virus ?
Is it safe to use the /fixmbr ?
If i try it will it delete any files on my computer, or do i have to reinstall any of my programs that are already installed ?

Ps: I just tried a rootkit scanner from trend micro.
Nothing showed up, so is this scan helpful ?
Here's the log from that scan :


+----------------------------------------------------
| Trend Micro RootkitBuster
| Module version: 2.80.0.1077

Our HJT team uses custom scripts and programs that we cannot run here in this forum

I recommend you submit a DDS / HJT log


Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

You will also be instructed to create a Root Repeal Log. Just use what you already have.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

The HJT team is very busy and it will take awhile to get to your post
Please be patient and good luck
