Hello Everyone,

I am 99% sure that I am infected with wmitxjk.exe as described on these sites;
this
and
this one (spanish)

All the tell-tale signs are there, spamming of stuff on Messenger, replication with ndisvvan.sys, the dirty reg entries, highjacking of the hosts file etc.
Avast also detects it but cant delete it, saying it is used by another program. Avast then tries a boot scan but can not see it.

I was gonna try the fixes that are stated in the sites above but I cant boot to safe mode (system reboots after going to SPTD.sys) and I dont have my XP disc, though I can get one through our school's MSDNAA program. (will take a day or two though).

For the meantime can anybody help me with a solution that does not involve going to safe mode. I am running win XP pro w/ SP3

Also, does this thing spread over a home network? Our house has two computers in it connected with a router, seems like the other computer is infected as well.

edit : Messing around with the command prompt revealed another file in my system32 folder wmitxjr.exe I think its the same thing but the sites above are saying it should be wmitxjk.exe. Any thoughts?

I thank you for time good sirs/ma'ams. And also a Happy Valentines Day to all (those who are celebrating it, that is ) :thumbsup:

No replies :flowers:

But anyways just posting information for those who experience the same problem, I managed to clean the stuff off my computer by taking my HDD off my computer and plugging it to a PC in our schools networking lab, ran an AV scan on the HDD from there and deleted all files that are listed in the links. Afterwards I plugged in the HDD back to my comp, booted up and deleted all the registry entries, took a whole afternoon. :thumbsup:

Hello,sorry we could not get to you sooner.. you did well and thanks for posting back.. This is a dropper trojane and I was hoping you would run another scan to be certain.

Please download TFC by Old Timer and save it to your desktop.
alternate download link
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.


Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

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.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • 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.

Hello boopme and thanks for the reply,

My computer is running fine till today, so I decided to return back to this forum, so I apologize if my reply is a bit late.

Scan came out postive :thumbsup: , also added to that the computer can not connect to the net anymore (the main reason I went back here), so I cant update Malwarebytes Anti-Malware.

Tinkering around I noticed a few things that seemed suspicious,
- running the ipconfig command just displays the string
"Windows IP Configuration"
It does not display the other information (IP Addresses)
- when I tried to ping my router it displays
"Destination host unreachable"
- Trying to repair the LAN connection gives me this error
"Windows could not finish repairing the problem because the following action cannot be completed:
Failed query TCP/IP settings of the connection.Cannot proceed"

As a firsthand measure I will check for hardware faults first. Both my router and modem work fine as I can still log on and post here (not on the computer in question of course), tomorrow I will borrow a friend's laptop and check if the Ethernet cable is the one causing the problem.


Anyways heres the log.

Doing the netsh winsock reset thing didn't do anything to fix my problem.

I was able to update MBAM thru the link in the second post. Though lack of internet resources still hampered my super-anti spyware update. I am still not able to boot in safe mode(the comp still resets while loading SPTD.sys )

On the otherside, I think I am clean now MBAM only reports a registry issue and super-anti spyware reported only false positives.

Now the only thing that is broken is the connection issue, any ideas? Should I go replace TCPIP.sys. Do a complete TCP/IP reinstall-install? (as posted in other parts of the forum)
Again, I thank you kind beepme you really have been a great help.

Hi, did you look the proxy box,you didn;t say.
Try this--open control, internet options, connections tab, lan settings, uncheck the box next to "use proxy...."

TRY..
Go Start > Run > type: "cmd" In the window that appears type: "ipconfig /flushdns". Close the command box.

Go Start > Control Panel > Network Connections. Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties. Double-click on the Internet Protocol (TCP/IP) item. Select the radio button that says "Obtain DNS servers automatically". Reboot. Warning: Some Internet Service Providers need specific DNS settings. You need to make sure that you know if such DNS settings are required before you make this change.

Also

Microsoft KB article to reset TCP/IP
One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it.
Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh)

You're welcome from us all.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
