Hello

Two days ago my AVG Free found a Trojan horse in file Windows\system32\ntos.exe.

As I've read it's Win32.Banker.cmb virus. I've deleted files ntos.exe, \wsnpoem\audio.dll, wsnpoem\video.dll and removed part of the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] Value "Userinit". After that for a day my internet connection did not work, but now it's ok again.

And so I have several questions:
1. Did I removed it completely or there are some additional things that should be done? (Some elements of HijackThis log is in Russian, sorry)
2. What free anti-spyware soft would you advice to use? I use Comodo BOC, but it seems not doing a great job.

My HyjackThis log:

Hi

Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

Please then reboot your computer in Safe Mode by doing the following :
  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  • Instead of Windows loading as normal, the Advanced Options Menu should appear;
  • Select the first option, to run Windows in Safe Mode, then press Enter.
  • Choose your usual account.
  • Open the extracted SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    (Report.txt will also be copied to Clipboard ready for posting back on the forum).
  • Finally paste the contents of the Report.txt back in your next reply.



If you already have Combofix, please delete that copy and download it again as it's being updated regularly.

There is a tutorial on the basic use of Combofix here:
http://www.bleepingcomputer.com/combofix/how-to-use-combofix


Please download Combofix from Bleeping Computer.

If you can't download it from there, please try these 2 alternative sites:

Forospyware
Geeks to Go

  • Save it to your Desktop.
  • Disconnect from the Internet, than disable your anti-virus and any real-time anti-spyware monitors that are running.
  • Click Start>Run copy/paste or type "%userprofile%\desktop\combofix.exe" /killall into the Run box and click OK.
  • When finished, it shall produce a log for you. Post that log in your next reply with a new HijackThis log.
1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you – please tell your helper.
4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.
