BC Miner trojan

[isps1969]

Cannot remove infected files using Malwarebytes Anti-Malware, observed other posts and decided to start own post. I hope you can assist me with the issue. One note, I attempted to attempt system recovery steps from other posts and had no luck with exact steps. BIOS loads w/ F12 for me and options are to boot from a specific disc or in Set-Up the Boot Options do not offer a Repair Your Computer option. Using instillation disc is not an option. Please advise when possible. Thank you.

I was able to access BIOS correctly and can attempt System Recovery steps when neccessary.

Welcome to the forum.

Your computer is infected with a nasty rootkit. Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

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

One or more of the identified infections is known to use a backdoor.

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

I would advice 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 infection has been identified and 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:

When Should I Format, How Should I Reinstall

http://www.dslreports.com/faq/10063

I will try my best to 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 decide to go through with the cleanup, please proceed with the following steps.

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

Please make sure system restore is running and create a new restore point before continuing!

For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.

For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

How to tell > 32 or 64 bit

Plug the flashdrive into the infected PC.

Enter System Recovery Options.

To enter System Recovery Options from the Advanced Boot Options:

• Restart the computer.
  
• As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  
• Use the arrow keys to select the Repair your computer menu item.
  
• Select US as the keyboard language settings, and then click Next.
  
• Select the operating system you want to repair, and then click Next.
  
• Select your user account an click Next.
  

To enter System Recovery Options by using Windows installation disc:

• Insert the installation disc.
  
• Restart your computer.
  
• If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  
• Click Repair your computer.
  
• Select US as the keyboard language settings, and then click Next.
  
• Select the operating system you want to repair, and then click Next.
  
• Select your user account and click Next.
  

On the System Recovery Options menu you will get the following options:

• 
  
  • 
    Startup Repair
    System Restore
    Windows Complete PC Restore
    Windows Memory Diagnostic Tool
    Command Prompt
    

  [*]Select Command Prompt

  [*]In the command window type in notepad and press Enter.

  [*]The notepad opens. Under File menu select Open.

  [*]Select "Computer" and find your flash drive letter and close the notepad.

  [*]In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter

  Note: Replace letter e with the drive letter of your flash drive.

  [*]The tool will start to run.

  [*]When the tool opens click Yes to disclaimer.

  [*]Press Scan button.

  [*]FRST will let you know when the scan is complete and has written the FRST.txt to file, close out this message, then type the following into the search box:

  services.exe

  [*]Now press the Search button

  [*]When the search is complete, search.txt will also be written to your USB

  [*]Type exit and reboot the computer normally

  [*]Please copy and paste both logs in your reply.(FRST.txt and Search.txt)

I actually performed a restore to several days prior and while BC Miner was gone the svchost was still recognized as a trojan virus. Here are the updated files.

Note: I attempted to run steps provided for frst64, but prompt would not allow me to change from X drive to flash drive.

Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.

A report will be created in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste its contents on your next reply.

Sometimes these logs can be very large, in that case please attach it or zip it up and attach it.

That scan looks much better, next.............

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingc...to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

Here is the combofix log.

Looks Good.....

Please Update and run a Quick Scan with MBAM, post the report.

Make sure that everything is checked, and click Remove Selected.

Please let me know how computer is running now, MrC

[isps1969]

Computer appears to be running fine. MBAM found no issues, I believe. 3 files remain present in the Quarantine section though: svchost.exe and two files listed as Trojan.VUPX.PT11. Should I delete all three of these files, just the later two or leave as-is?

Great

You can delete them.

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

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

Please download OTL from one of the links below: (you may already have OTL on the system)

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, etc....

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

Any questions...please post back.
