The computer has run slowly for about a week now. Ran Malware Bytes and Microsoft Security Essentials. It picks up Sirefef.E and Sirefef.D and quarantines and removes it. It comes back within minutes. So frustrating and I am worried about other damage it may be doing!

Firefox will also randomly open a webpage - eminentsearch or Lycos or some other odd search page.

I appreciate any help you can offer!!!

  • 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.

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.

Welcome to Bleeping Computer

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.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process. Please also continue to work with me until I give you the all clear. Even if your computer appears to act better, you may still be infected.

Even if you have already provided information about your PC, we need a new log to see what has changed since you originally posted your problem.

Once we start working together, please reply back within 3 days or this thread may be closed so we can help others who are waiting.

We need to create an OTL report,
  • Please download OTL from this link.
  • Save it to your desktop.
  • Double click on the Posted Image icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • Under the Custom Scan box paste this in:

    netsvcs
    msconfig
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll
    %systemroot%\*. /mp /s
    %systemroot%\system32\*.sys /90
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\system32\*.exe /lockedfiles
    %systemroot%\System32\config\*.sav
    %PROGRAMFILES%\*
    %USERPROFILE%\..|smtmp;true;true;true /FP
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
    hklm\software\clients\startmenuinternet|command /rs
    hklm\software\clients\startmenuinternet|command /64 /rs
    CREATERESTOREPOINT
  • Click the Quick Scan button.
  • The scan should take a few minutes.
  • Please copy and paste both logs in your reply.

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


In your reply, please post both OTL logs and the GMER log.


If I don't respond within 2 days, please feel free to PM me.
Please don't ask for help via PM. The forums are there for a reason. Please post in the forums so others may benefit as well.

Hello, kimbly.


Step 1



Next, please download ComboFix from one of these locations:
* IMPORTANT !!! Save ComboFix.exe to your Desktop as etavaresCF.exe
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on etavaresCF.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.


Posted Image
Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply, along with any symptoms that are present after it runs.

Note: After running Combofix, you may receive an error about "illegal operation on a registry key that has been marked for deletion." If you receive this error, please reboot and it should disappear.

Hello, kimbly.
Backdoor Warning
One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do. If you do decide to proceed, please continue with the fix below.



Step 1



1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Open Notepad and copy/paste the text in the codebox below into Notepad:

Folder::
c:\documents and settings\Cheryl\Local Settings\Application Data\a69c7bca
Firefox::
FF - ProfilePath - c:\documents and settings\Cheryl\Application Data\Mozilla\Firefox\Profiles\y5uaqo2l.Cheryl\
FF - prefs.js: browser.search.defaulturl - hxxp://search.conduit.com/ResultsExt.aspx?ctid=CT2857573&SearchSource=3&q={searchTerms}
File::
c:\windows\system32\drivers\mjubbmrv.sys
c:\windows\system32\drivers\sciuhxbx.sys

Save this as CFScript.txt, in the same location as ComboFix.exe


Posted Image

Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Note: After running Combofix, you may receive an error about "illegal operation on a registry key that has been marked for deletion." If you receive this error, please reboot and it should disappear.



Step 2

We need to scan the system with this special tool:

* Please download and save:

Junction.zip

* Unzip it and place Junction.exe in the Windows directory (C:\Windows).
* Go to Start => Run... => Copy and paste the following command in the Run box and click OK:

cmd /c junction -s c:\ >log.txt&log.txt& del log.txt

A command window opens starting to scan the system. Wait until a log file opens. Copy and paste the log in your next reply.
