I somehow contracted the Multidropper Fk Trojan and after reviewing the forum advice ran ComboFix and would like an analysis of the log to see if there is anything I need to do at this point. I realize now that I was not supposed to run ComboFix without being instructed to so that was my first mistake. :thumbsup:

Anytime I reboot my computer I have to select "Last known good configuration" since it won't boot in Safe Mode and when it does boot up it is very slow.

Thank you for any help with this.

Some types of malware will disable Malwarebytes Anti-Malware and other security tools. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe.
  • Double-click on mysetup.exe to start the installation.
  • If that did not work, then try renaming and changing the file extension. <- click this link if you do not see the file extension
  • Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to myscan.exe.
  • Double-click on myscan.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

Be sure to update MBAM through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the report in your next reply.

Note: MBAM uses Inno Setup instead of the Windows Installer Service to install the program. If installation fails in normal mode, try installing in safe mode. Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.



------------------------------------

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

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

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

  • 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 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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

Ok, I left out some important information earlier;

When my CA anti spyware found the Multidropper Fk I updated MB and ran a scan which found nothing and after searching Google I found this forum which had instructed another member to run ComboFix which is what I did and I do have the log from that scan.

I just updated and ran another MB scan which again found nothing so I am unsure of what to do next, hence why I am here.

I appreciate your help.

Thanks!

ComboFix logs should not to be posted or discussed outside the HijackThis forums. It is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.
-------------------------------------------------


Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

There will also be instructions to create a Root Repeal Log

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

The HJT team is very busy and it will take awhile to get to your post
Please be patient and good luck
