Problems with Trojan.dialer.pz and vtstt.dll, and just recovered from Trojan.nebuler.

Hi and welcome


Please scrap the HJT log you have already and follow the guide below as these steps will remove alot of the malware and issues you may have that HJT alone cannot do,

- Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support

Make sure you check version numbers and get all updates.

After doing ALL of the above you still have a problem make sure you have booted to normal mode and run the steps in the below link to properly use HijackThis and attach a log:

Downloading, Installing, and Running HijackThis


When you return to make your next post, make sure you attach the following logs and that you have run these scans in the following order too (these scans are covered in steps 6 & 7 of the READ & RUN ME sticky)

• Bitdefender
• Panda Scan
• HijackThis

.

 

That is a Virtumonde infections. Let's try the easy fix first. It may not work as there seems to be a load of new forms of this infection out there in the last week. If it does not work, we will use a manual approach.

Virtumonde aka Trojan Vundo Removal

Attach the log from VundoFix afterwards.

Also please follow the directions in step 7 of the READ ME and install HijackThis properly. You have it installed exactly where we tell you not to install it.

Also Run the below procedure and attach the newfiles.txt log.

• Using ShowNew

 

Start by downloading two tools we will need

- Process Explorer

- Pocket KillBox

Extract them to their own folder somewhere that you will be able to locate them later.

IMPORTANT: You should print or save the below locally, so you can refer to them while offline. You must exit all browsers before running the below steps and it would be best if you actually physically unplug your cable to the internet, reboot, and do not run anything but what I give you to do. Also it would be good to exit all processes and items in your System tray.

Do the above before continuing! Okay unplug your cable now.

Make sure you have rebooted in Normal Mode (do not open any other processes)

- Run Process Explorer

In the top section of the Process Explorer screen double click on winlogon.exe to bring up the winlogon.exe properties screen. Click on the Threads tab at the top.

Once you see this screen click on each instance of vtstt.dll once and then click the kill button. After you have killed all of the vtstt.dll under winlogon click ok. (If you do not find the dll, just continue on.)

Next double click on explorer.exe and again click once on each instance of vtstt.dll and kill it. (If you do not find the dll, just continue on.)

Now just exit Process Explorer.

Run HijackThis and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

O23 - Service: Asnartsf - Unknown owner - (no file)

Copy the bold text below to notepad. Save it as fixme.reg to your desktop.
Be sure the "Save as" type is set to "all files"
Once you have saved it double click it and allow it to merge with the registry.

Now run Pocket Killbox by doubleclicking on killbox.exe
Choose Tools > Delete Temp Files and click Delete Selected Temp Files.
Then after it deletes the files click the Exit (Save Settings) button.
Now back on Killbox's main window, Paste the below filenames into KILL BOX one at a time. Check mark the box that says "Delete on Reboot" and checkmark the box "Unregister DLL" (If available) Click the RED X and it will ask you to confirm the file for deletion…say YES and when the next box opens prompting you to reboot now...click NO...and proceed with the next file. Once you get to the last one click YES and it will reboot. Note some of the files listed below may not exist but we need to check for them anyway.

C:\WINDOWS\SYSTEM32\vtstt.dll
C:\WINDOWS\SYSTEM32\ttstv.ini


If Killbox does not reboot or you get a Pending Operations type error message just reboot your PC yourself.

Now attach a new HJT log and a new log from ShowNew.

Also tell me how the steps went.

Make sure you tell me how things are working now!

 

We're almost there! Now that we removed the bad files, they showed up in your HJT log! So fix the below. The O23 item seems to be back.. Did you get an error message about fixing it?


O2 - BHO: (no name) - {47AF0959-E8B5-4CBE-8ACB-3D0C1FA88E27} - C:\WINDOWS\system32\vtstt.dll (file missing)
O20 - Winlogon Notify: vtstt - C:\WINDOWS\system32\vtstt.dll (file missing)
O23 - Service: Asnartsf - Unknown owner - (no file)

Let me know if the O23 line comes back.

 

Click on Start, then Run ... type services.msc into the box that opens up, and press 'OK'. On the page that opens, scroll down to Asnartsf ... then right click the entry, select 'Properties' and press 'Stop Service'. When it shows that it is stopped, next please set the 'Start-up Type' to 'Disabled'. Press 'OK' until you get back to Windows.

Next, run HJT, but instead of scanning, click on the "None of the above, just start the program" button at the bottom of the choices. At the lower right, click on the 'Config" button, and then the Misc tools' button ... select 'Delete an NT Service" ... copy/paste the following into the box that opens, and press "OK":

Asnartsf

If you receive any error messages just ignore them and continue.

Now exit HJT and reboot if it tells you it needs to.
After reboot check to see if the O23 line is gone.

 

My last instructions had the below line in it!

Thus I expected error and just wanted you to continue thru each step and ignore errors.

You don't really expect me to be able to read that file you posted do you! How did you format it like that?

Download GetService.zip from here: Getservice.zip

Extract the file to a folder where you can find it, then go to the folder and double-click on the getservices.bat file. A notepad will open up. Save it to a file named services.txt and upload it here as an attachment.


Also download the Registry Search Tool

Unzip to your Desktop and double click on regsrch.vbs
(if you have script protection, please allow this to run)

In the dialog that opens enter the following:

Asnartsf

Press 'OK'

The search will run for a while then alert you when it is finished. Press 'OK' and copy the contents of the WordPad window and post in this thread as an attachment.

 

Run Regsrch again and just copy and paste the info here if you cannot save the file. I need to see that before we continue.

 

Click Start, Run, and enter wordpad and click OK!

Does a Wordpad windows open up?

 

Copy the bold text below to notepad. Save it as fixme.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

Now do the RegSrch procedure again and attach the new log. Also attach a new HJT log.

 

Your log is clean. If you are not having any other malware problems, it is time to go back to step 1 of the READ & RUN ME to Disable System Restore which will flush your Restore Points. Then reboot and enable System Restore to create a new clean Restore Point.

After that, you should work thru the below link:
