Hi everyone,

Combofix log just cleaned out a rootkit that I'm pretty sure came in via a Java Applet in Chrome. It also gave me a fun "Security Tool" spyware infection. I was hoping someone could confirm or deny my suspicions based on the log.

Hi radiocolin,

Welcome to Bleeping Computer!

My name is mpascal, and I will be helping you fix your problem.

Before we begin, I would like give a few guidelines so that we can fix your problem as quickly and efficiently as possible:
  • Be sure to follow all my instructions carefully! If there is anything you don't understand, don't hesitate to ask.
  • Please do not do anything or perform other steps unless I have asked you to do so.
  • Please make sure you post all logs I ask you to, and make sure that the entire log gets posted.
  • Don't attach any logs unless asked. Posting them in the forums will make them easier to analyze.
  • If you are unsure of how to reply, or need help with anything regarding the website, please look here.

STEP 1 - Preparation Guide

Please follow the instructions in the Preparation Guide until you have reached step 6. You may stop once you have finished step 6 and continue with the instructions here.

STEP 2 - MBAM

Note: In the event that you already have MBAM installed, you do not need to reinstall it. Simply Updating it and doing a Quickscan is sufficient.

Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.

STEP 3 - GMER

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.

STEP 4 - OTL

Download OTL to your desktop.
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • In the Custom Scans box, copy and paste the following:
    CODE
    netsvcs
    %SYSTEMDRIVE%\*.*
    %systemroot%\Fonts\*.com
    %systemroot%\Fonts\*.dll
    %systemroot%\Fonts\*.ini
    %systemroot%\Fonts\*.ini2
    %systemroot%\Fonts\*.exe
    %systemroot%\system32\spool\prtprocs\w32x86\*.*
    %systemroot%\REPAIR\*.bak1
    %systemroot%\REPAIR\*.ini
    %systemroot%\system32\*.jpg
    %systemroot%\*.jpg
    %systemroot%\*.png
    %systemroot%\*.scr
    %systemroot%\*._sy
    %APPDATA%\Adobe\Update\*.*
    %ALLUSERSPROFILE%\Favorites\*.*
    %APPDATA%\Microsoft\*.*
    %PROGRAMFILES%\*.*
    %APPDATA%\Update\*.*
    %systemroot%\*. /mp /s
    CREATERESTOREPOINT
    %systemroot%\System32\config\*.sav
    %PROGRAMFILES%\bak. /s
    %systemroot%\system32\bak. /s
    %ALLUSERSPROFILE%\Start Menu\*.lnk /x
    %systemroot%\system32\config\systemprofile\*.dat /x
    %systemroot%\*.config
    %systemroot%\system32\*.db
    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 Run 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. OTListIt.Txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of the files, and post it with your next reply.
STEP 5 - Reply

Please reply with the following logs:
  • MBAM Log
  • GMER Log
  • OTL Log
