Hi,


my computer has been hit yesterday, by a couple of trojans. Since then I am trying to fight them off, but some of them just won`t go away. I posted a Highjack file in a german forum, and the response was to reinstall the whole system, because it was redirecting to an ucrainian nameserver. After surfing a little bit more I found this habour here, beause some other fellow had the same Nameserver redirection that I have right now. I did already a Highjack and a Fixwareout

Do you have any suggestions

Fixwarout

ixwareout ver 1.003

Hey Dirk, welcome to Bleeping Computer.

It is a good idea to print off these instructions:
This will be useful as there is a possibility some of the instructions will need to be carried out where internet access is not available.
You may also like to save these instructions in word/notepad to the desktop where they can be easily found for the same reasons as above.
A print out of the instructions would be a good reference to make sure you don't yet lost.
Also, it is important that you complete the instructions in the right order, and also that you don't miss any steps out!
If you have any queries about the process or just general questions, just ask.

You are using the eMule p2p file sharing program.
This is not technically malware by itself, but it installs malware in order to run properly.
It also opens the door for every other nasty program you can think of.
I strongly recommend that you remove it from your computer.
Read this article for alternatives that will provide some of the same function without the garbage:
http://www.spywareinfo.com/articles/p2p/

I suggest you remove the program now.
Go to Start > Settings > Control Panel > Add/Remove Programs and remove the following programs if present:
eMule

This is another article you can read:
http://www.cexx.org/adware.htm

Your Java is out of date and the older versions are being exploited by malware.
It is the likely cause of your infection, so we need to get it patched up as soon as possible.
Click on start, then control panel, and then double-click on add/remove programs.
Search in the list for all older installed versions of Java. (J2SE Runtime Environment.... )
It should have next icon next to it: Posted Image
Highlight each and click Remove.
Then Download and install the newest version from here:
http://www.java.com/en/download/manual.jsp

Download KillBox from the following link :
http://www.bleepingcomputer.com/files/killbox.php
Unzip the folder to your desktop.
Don't run it yet!

Please open the Hijackthis program.
Click on the "Do a system scan only".
Place a tick next to the following entries.
Do not be concerned if you cannot find them in the list:

O17 - HKLM\System\CCS\Services\Tcpip\..\{1D252062-99AC-4ACE-89BE-A51927695E30}: NameServer = 85.255.113.90,85.255.112.5
O17 - HKLM\System\CCS\Services\Tcpip\..\{836E3213-99D7-4096-919E-D1B53EE5082}: NameServer = 85.255.113.90,85.255.112.5
O17 - HKLM\System\CCS\Services\Tcpip\..\{D237D8EB-A798-47E6-98DF-1F049B2D5368}: NameServer = 85.255.113.90,85.255.112.5
O17 - HKLM\System\CS1\Services\Tcpip\Parameters: NameServer = 85.255.113.90 85.255.112.5
O17 - HKLM\System\CS2\Services\Tcpip\Parameters: NameServer = 85.255.113.90 85.255.112.5
O17 - HKLM\System\CCS\Services\Tcpip\Parameters: NameServer = 85.255.113.90 85.255.112.5


Make sure your Internet Explorer is closed.
Click on the "Fix Checked" button and exit HijackThis when finished.

* Go to Control Panel. - If you are using Windows XP's Category View, select the Network and Internet Connections category. If you are in Classic View, go to the next step .
  • Double-click the Network Connections icon
  • Right-click the Local Area Connection icon and select Properties.
  • Hilight Internet Protocol (TCP/IP) and click the Properties button.
  • Be sure Obtain DNS server address automatically is selected.
  • OK your way out.
* Go to Start > Run and type in cmd
Click OK.
This will open a commad prompt.
Type or copy and paste the following line in the command window:

ipconfig /flushdns

Hit Enter
Exit the command window

Start Killbox.exe
Select the "Delete on Reboot" option.
Click on the "All Files" button (!important!),which will then flash green.
Copy the complete text in bold below to the clipboard by highlighting the filepaths and pressing Control + C:

C:\WINDOWS\SYSTEM32\CSNFP.EXE
C:\WINDOWS\SYSTEM32\DMLJK.EXE
C:\WINDOWS\SYSTEM32\{2DD1398C-974D-45A3-A321-C7CA5B4D255F}.exe


Open 'file' in the killboxmenu on top and choose Paste from clipboard
You must use the file File menu--pasting by right-clicking the mouse will only enter one file.
Then press the button that looks like a red circle with a white X in it.
Killbox will tell you that all listed files will be removed on next reboot and asks if you would like to Reboot now, click "yes".
Click OK at any Pending File Rename Operations prompt, let me know if there appear.
If you don't get that message, reboot manually.
Your computer should reboot now.

Download WinpFind.
Extract WinPFind.zip to your c:\ folder.
Reboot into Safe Mode ( without networking support !)
To get into the Safe mode as the computer is booting press and hold your "F8 Key".
Use your arrow keys to move to "Safe Mode" and press your Enter key.
Then open c:\WinPFind and double-click on WinPFind.exe.
When the program is open, click on the Start Scan button to scart scanning your computer.
Be patient as this scan may take a while.
When it is done, it will show a log and tell you the scan is completed.
Reboot your computer back to normal mode and and post the contents of the log as a reply to this topic, along with a new Hijackthis log.

David
