Recommended Posts

Hello ofudd! Welcome to MalwareBytes' Anti-Malware Forums!

My name is Borislav and I will be glad to help you solve your problems with malware. Before we begin, please note the following:

  • The process of cleaning your system may take some time, so please be patient.
  • Stay with the topic until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  • Instructions that I give are for your system only!
  • If you don't know or can't understand something please ask.
  • Do not install any software or hardware, while work on.

Please visit Combofix Guide & Instructions for instructions for installing the recovery console and downloading and running ComboFix.

The only thing different from the instructions there is that when downloading and saving the ComboFix.exe I would like you to rename it to Combo-Fix.exe please.

Post the log from ComboFix when you've accomplished that along with a new HijackThis log.

Important notes regarding ComboFix:

ComboFix may reset a number of Internet Explorer's settings, including making it the default browser. This can easily be changed once we're finished.

ComboFix also prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you, please let me know. This can be undone manually when we're finished. Read HERE for an article written by dvk01 on why we disable autoruns.

Note: During this process, it would help a great deal and be very much appreciated if you would refrain from installing any new software or hardware on this machine, unless absolutely necessary, until the clean up process is finished as it makes our job more tedious, with additional new files that may have to be researched, which is very time consuming.

Also, please do not run any security programs or fixes on your own as doing so may compromise what we will be doing. It is important that you wait for instructions.

In your next reply, please include these log(s):

* ComboFix log

* DDS log (new) with Attach.txt

Step 1:

Please uninstall the following applications:

McAfee Security Scan

Norton Security Scan

FrostWire 4.18.5

LimeWire 5.3.6

McAfee Security Scan and Norton Security Scan are unnecessary because you have Avira Antivir.

FrostWire and LimeWire violate our rules.

Step 2:

Please go into the Control Panel, Add/Remove and for now remove ALL versions of JAVA

Then run this tool to help cleanup any left over Java

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.

Please download JavaRa and unzip it to your desktop.

***Please close any instances of Internet Explorer (or other web browser) before continuing!***

  • Double-click on JavaRa.exe to start the program.
  • From the drop-down menu, choose English and click on Select.
  • JavaRa will open; click on Remove Older Versions to remove the older versions of Java installed on your computer.
  • Click Yes when prompted. When JavaRa is done, a notice will appear that a logfile has been produced. Click OK.
  • A logfile will pop up. Please save it to a convenient location and post it back when you reply
    Then look for the following Java folders and if found delete them.
    C:\Program Files\Java
    C:\Program Files\Common Files\Java
    C:\Windows\Sun
    C:\Documents and Settings\All Users\Application Data\Java
    C:\Documents and Settings\All Users\Application Data\Sun\Java
    C:\Documents and Settings\username\Application Data\Java
    C:\Documents and Settings\username\Application Data\Sun\Java

Step 3:

Open Notepad and copy and paste the text in the code box below into it:

KillAll::

File::
c:\users\jon\AppData\Local\Temp\HNGTF.exe
c:\users\jon\AppData\Local\Temp\PPCKS.exe
c:\users\jon\AppData\Local\Temp\TOSDEMDTE.exe
c:\users\jon\AppData\Local\Temp\ZFFTAVEIL.exe

Driver::
HNGTF
PPCKS
TOSDEMDTE
ZFFTAVEIL

Save the file to your desktop and name it CFScript.txt

Then drag the CFScript.txt into the ComboFix.exe as shown in the screenshot below.

CFScriptB-4.gif

This will start ComboFix again. It may ask to reboot. Post the contents of Combofix.txt in your next reply together with a new HijackThis log.

Note: These instructions and script were created specifically for this user. If you are not this user, do NOT follow these instructions or use this script as it could damage the workings of your system.

Step 4:

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_zip.gif
  • 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 re-enable all active protection when done.

-- If you encounter any problems, try running GMER in Safe Mode.

In your next reply, please include these log(s):

* JavaRa log

* ComboFix log

* GMER log

I ran javara, but it did not popup a notice or produce a logfile that I could find.

after combofix and reboot, I could not start firefox or ie7:

"illegal operation attempted on a registry key that has been marked for deletion"

rebooted again and it worked.
