Help with computer infection

[steve22]

Hi,

For the past two weeks I've noticed some suspicious behavior on my computer and believe it is infected. My browser occasionally opens a new tab usually with some kind of ad site and Google sometimes redirects to these sites as well. Also, I have not been able to perform a System Restore as the infection seems to have blocked or corrupted any restore points. MBAM appears to have removed one infection during a quick scan but if I run a full scan the computer automatically shuts down. I also ran a full scan with McAfee and it did not detect anything. I performed the rest of the instructed steps for this forum except for the GMER scan. I kept getting the BSoD everytime I ran it. I am posting/attaching the other logs as well as the dump file for the GMER crash (if it helps). I tried to include the DDS log in the post but it would not submit so I added it to the .zip file. Please let me know if any more information is needed. Thank you for your time and I appreciate any help.

Hello steve22

Welcome to Malwarebytes.

Try gmer once more and let me know the outcome.

=====================

• Download OTL to your desktop.
  
• Then double click on OTL to start the program.
  
• When the window appears, underneath Output at the top change it to Minimal Output.
  
• Under the Standard Registry box change it to All.
  
• Under Custom scan's and fixes section paste in the below in bold
  

  
  

  netsvcs
  
  
  %SYSTEMDRIVE%\*.*
  
  
  %systemroot%\*. /mp /s
  
  
  CREATERESTOREPOINT
  
  
  %systemroot%\system32\*.dll /lockedfiles
  
  
  %systemroot%\Tasks\*.job /lockedfiles
  
  
  %systemroot%\System32\config\*.sav
  
  
  %systemroot%\system32\drivers\*.sys /90

  
  

• Check the boxes beside LOP Check and Purity Check.
  
• 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. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    
  • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.
    

====================

Download the following GMER Rootkit Scanner from Here

• Download the randomly named EXE file to your Desktop. Remember what its name is since it is randomly named.
  
• Double click on the new random named exe file you downloaded and run it. If prompted about the Security Warning and Unknown Publisher go ahead and click on Run
  
• It may take a minute to load and become available.
  
• If it gives you a warning about rootkit activity and asks if you want to run a full scan...click on NO, then use the following settings for a more complete scan..
  
• In the right panel, you will see several boxes that have been checked. Ensure the following are UNCHECKED
  

  
  

• IAT/EAT
  
  
• Drives/Partition other than Systemdrive (typically only C:\ should be checked)
  
  
• Show All (don't miss this one)

  
  

• Then click the Scan button & wait for it to finish.
  
• Once done click on the [save..] button, and in the File name area, type in "ark.txt" or it will save as a .log file which cannot be uploaded to your post.
  
• Save it where you can easily find it, such as your desktop
  
• **Caution** Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries
  
• Click OK and quit the GMER program.
  
• Note: On Firefox you need to go to Tools/Options/Main then under the Downloads section, click on Always ask me where to save files so that you can choose the name and where to save to, in this case your Desktop.
  
• Post that log in your next reply.

Thank you for the assistance. I've attached the logs for OTL. I was unable to run GMER, the computer restarted during the scan. If there is something else I can do to get the GMER scan to complete please let me know. Thanks.

Hi try to uncheck everything with Gmer but for the Sections option and the C:\Drive near the bottom.

Post the log if that works if not we will go on to something else.

[steve22]

Hi kahdah,

Here is the GMER log. I was able to run it after I unchecked Files.

Thanks.

Looking at your system now, one or more of the identified infections is a backdoor Trojan\Rootkit.

If this computer is ever used for on-line banking, I suggest you do the following immediately:

1. Call all of your banks, credit card companies, financial institutions and inform them that you may be a victim of identity theft and to put a watch on your accounts or change all your account numbers.

2. From a clean computer, change ALL your on-line passwords for email, for banks, financial accounts, PayPal, eBay, on-line companies, any on-line forums or groups you belong to.

Do NOT change passwords or do any transactions while using the infected computer because the attacker will get the new passwords and transaction information.

=====================

Download ComboFix from one of these locations:

Link 1

Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

• Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
  
• Double click on ComboFix.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.

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

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.

[steve22]

Thank you for the heads up.

I have tried running ComboFix but the computer is crashing. It states that it is scanning for infected files and sometime afterwards it crashes.

[kahdah]

Kangaroo someone is helping you in one of your topics.

Please do not post in this topic.

=====================

Steve22 please do the following:

Please download SystemLook from one of the links below and save it to your Desktop.

Download Mirror #1

Download Mirror #2

• Double-click SystemLook.exe to run it.
  
• Copy the content of the following codebox into the main textfield:
  

  :filefind
  mouclass.*

  
  

• Click the Look button to start the scan.
  
• When finished, a notepad window will open with the results of the scan. Please post this log in your next reply.
  

Note: The log can also be found on your Desktop entitled SystemLook.txt

[steve22]

Here is the log for SystemLook. Thanks kahdah.

If the Recovery Console was installed with Combofix then you can skip the steps about downloading the cd.

Download RC.ISO and burn it to a cd as an ISO image. You may need a burning toy like ISO Recorder to do this...be sure to get the version for your operating system.

Once you have burned this as an ISO image, insert the CD into the drive, and then restart the computer. Watch for the prompt to "Press any key to boot from cd" and press the spacebar when you see it. You may have to change the boot priority in BIOS Setup to accomplish this...we'll cross that bridge if we get to it.

When the "Welcome to Setup" screen appears, press R to start the Recovery Console.

If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console...by number (usually 1)

When you are prompted to do so, type the Administrator password. If you have not set an administrator password, leave it blank and just press "Enter".

At the Recovery Console command prompt, type ren C:\WINDOWS\system32\drivers\mouclass.sys mouclass.vir it should go back to the line you started with if successful.

At the next prompt, type the following bolded text, and press Enter:

copy C:\WINDOWS\$NtServicePackUninstall$\mouclass.sys C:\WINDOWS\system32\drivers\ then hit Enter. You should see a one file(s) copied message if successful.

At the next prompt, type the following bolded text, and press Enter:

exit

Windows will now begin loading try to then run gmer just as you did before and post that log please.

[steve22]

Recovery console was installed with ComboFix so I skipped the CD step. However, every time Recovery Console started up, it went to the BSoD stating the "...there was a problem and windows was shut down. Please check for viruses..." etc. Could it be a problem with the Recovery Console install or another block by the infection?

[kahdah]

OK what is the make and model of the computer?
