Trojan-infected spam email coming from my IP address

Solved
By gescom
Jul 16, 2010
  1. My ISP has notified me that they've received complaints of infected spam coming from my IP address, and have now cut off my internet because of it. In order for them to turn it back on, I have to fix it, then tell them what was removed. This is my office PC, so this is sort of urgent.

    Malwarebytes detected a rootkit agent and said it was to be removed on reboot, but it doesn't appear to have done that.
    I've tried running the GMER scan twice, but each time when it finished and I go to save the log, it freezes, so I don't have a log from that program. In the scan it quickly finds the same rootkit agent that Malwarebytes did.

    I appreciate the help!

    Note: If you have a previous version of TDSSKiller downloaded please delete it now and download a fresh copy using the links provided below

    Download TDSSKiller and save it to your Desktop.
    Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.
    Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

    If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
    When it is done, a log file should be created on your C: drive called TDSSKiller.txt please copy and paste the contents of that file here.

    Sorry, I didn't realize it wasn't finished. How long does the TDSSKiller scan typically take? I restarted it and it's been going now for nearly 4 hours and hasn't displayed anything more past what the partial log I posted shows. And the only input I've given it is pressing <Enter> like you said. Thanks for your help!

    That scan shouldn't be taking so long.
    Let's try something else...

    Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.

    There are 4 different versions. If one of them won't run then download and try to run the other one.

    Vista and Win7 users need to right click Rkill and choose Run as Administrator

    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    * Rkill.com
    * Rkill.scr
    * Rkill.pif
    * Rkill.exe


    • * Double-click on the Rkill desktop icon to run the tool.
      * If using Vista or Windows 7 right-click on it and choose Run As Administrator.
      * A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
      * If not, delete the file, then download and use the one provided in Link 2.
      * If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
      * Do not reboot until instructed.
      * If the tool does not run from any of the links provided, please let me know.

    Once you've gotten one of them to run then try to immediately run the following.

    Now download and run exeHelper.


    • * Please download exeHelper from Raktor to your desktop.
      * Double-click on exeHelper.com to run the fix.
      * A black window should pop up, press any key to close once the fix is completed.
      * A log file named log.txt will be created in the directory where you ran exeHelper.com
      * Attach the log.txt file to your next message.

    Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

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

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt"
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    Attached the logfiles. I tried disabling AVG before Combofix started, but my attempts apparently didn't work (and I couldn't find any way to do it in their interface).

    1. Please open Notepad
    • Click Start , then Run
    • Type notepad .exe in the Run Box.

    2. Now copy/paste the entire content of the codebox below into the Notepad window:

    Code:
    File::
    c:\windows\system32\drivers\adplkxf.sys
    c:\windows\Bgopohekafom.dat
    c:\windows\Mvubobuvogep.bin
    c:\windows\system32\drivers\klmd.sys

    3. Save the above as CFScript.txt

    4. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs



    * Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.

    Is there any reason, system restore is disabled, or you're not aware of it?

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

    Update your Java version here: http://www.java.com/en/download/installed.jsp

    OK, back from the weekend. Here's the online Kaspersky scan log.

    You have one, or more bad piece of mail. Most likely, some attachment.
    I don't want to yank a whole folder, so you'll have to be careful, when dealing with your mail.
    Make sure to scan every single attachment before opening it.
    Be careful with clicking on emails links.

    Now, we need to check one file. It may be false positive.

    Open Windows Explorer. Go Tools>Folder Options>View tab, put a checkmark next to Show hidden files, and folders.
    Upload following files to http://www.virustotal.com/ for security check:
    - C:\WINDOWS\SMINST\Recguard.exe
    IMPORTANT! If the file is listed as already analyzed, click on Reanalyse file now button.
    Post scan results.

    Good. This is what I thought :)

    OTL Clean-Up
    Clean up with OTL:

    * Double-click OTL.exe to start the program.
    * Close all other programs apart from OTL as this step will require a reboot
    * On the OTL main screen, press the CLEANUP button
    * Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

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

    Your computer is clean [​IMG]

    1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point.

    Turn off System Restore:

    - Windows XP:
    1. Click Start.
    2. Right-click the My Computer icon, and then click Properties.
    3. Click the System Restore tab.
    4. Check "Turn off System Restore".
    5. Click Apply.
    6. When turning off System Restore, the existing restore points will be deleted. Click Yes to do this.
    7. Click OK.
    - Windows Vista and 7:
    1. Click Start.
    2. Right-click the Computer icon, and then click Properties.
    3. Click on System Protection under the Tasks column on the left side
    4. Click on Continue on the "User Account Control" window that pops up
    5. Under the System Protection tab, find Available Disks
    6. Uncheck the box for any drive you wish to disable system restore on (in most cases, drive "C:")
    7. When turning off System Restore, the existing restore points will be deleted. Click "Turn System Restore Off" on the popup window to do this.
    8. Click OK

    2. Restart computer.

    3. Turn System Restore on.

    4. Make sure, Windows Updates are current.

    5. If any Trojan was listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    6. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

    7. Run defrag at your convenience.

    8. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html

    9. Please, let me know, how is your computer doing.
