Referred from here: http://www.bleepingcomputer.com/forums/topic419458.html ~ OB

I posted under the Am I infected Forum to verify what is going on and was told after some tests that some stronger tools and analisys was needed to resolve the issue I am having.

I noticed the issue one day when I started up my PC. At first I thought it was a hardware issue. After testing each individual piece of hardware I loaded the system up with a backup and the issue was back.

I tracked it down to an svchost.exe process where it would not only start monopolizing the CPU but also under the Process Explorer was sending out data to unknown websites via IP addresss

Here is my previous Post.
www.bleepingcomputer.com/forums/topic419458.html

I am attatching all the logs that were previously requested

DDS (dds.txt, attach.txt)
Security Check (checkup.txt)
Process Explorer (Procexp.txt, svchost.exe.txt)
miniToolbox (result.txt)

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

Posted Image In order to continue receiving help at BleepingComputer.com, YOU MUST tell me if you still need help or if your issue has already been resolved on your own or through another resource! To tell me this, please click on the following link and follow the instructions there.

CLICK THIS LINK >>> http://www.bleepingcomputer.com/logreply/419519 <<< CLICK THIS LINK



If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.

  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Hi,

Please do the following

Refer to the ComboFix User's Guide

  • Download ComboFix from one of these locations:

    Link 1
    Link 2

    * IMPORTANT !!! Place ComboFix.exe on your Desktop
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with ComboFix.


    You can get help on disabling your protection programs here
  • Double click on ComboFix.exe & follow the prompts.
  • Your desktop may go blank. This is normal. It will return when ComboFix is done. ComboFix may reboot your machine. This is normal.
  • When finished, it shall produce a log for you. Post that log in your next reply

    Note:
    Do not mouseclick combofix's window whilst it's running. That may cause it to stall.


    ---------------------------------------------------------------------------------------------
  • Ensure your AntiVirus and AntiSpyware applications are re-enabled.

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


NOTE: If you encounter a message "illegal operation attempted on registry key that has been marked for deletion" and no programs will run - please just reboot and that will resolve that error.

Hi,

Please do the following:

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  • They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:
Click Start > Run type Notepad click OK.
This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

KillAll::

FireFox::
FF - ProfilePath - c:\users\Aran\AppData\Roaming\Mozilla\Firefox\Profiles\yjwkxb34.default\
FF - Ext: XULRunner: {01A51FC5-AEC6-44C9-AA98-3728FEF5F1DB} - c:\users\Aran\AppData\Local\{01A51FC5-AEC6-44C9-AA98-3728FEF5F1DB}




Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"


Here's how to do that:

1.Click File;
2.Click Save As... Change the directory to your desktop;
3.Change the Save as type to "All Files";
4.Type in the file name: CFScript
5.Click Save ...

Posted Image
  • Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  • ComboFix may request an update; please allow it.
  • ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  • When finished, it shall produce a log for you.
  • Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.

The Computer seems to be running a little smoother but I still Notice random Spikes in CPU and Memory Usage from items that that pop up in the task manager and dissapear before I can catch what name they are or even get the Proccess explorer to open them up. I did catch one SVChost doing something similar to what the other one was doing but it stopped rather suddenly before I can run any other tests.
