Hello, Bleepingcomputer,

 

I accidentally installed a software bundle off a fake but convincing download button's website. I uninstalled the offending apps and my computer seemed to run without problems until days later, I found these suspicious processes called "Windows Process Manager (32 Bit)" eating at some of my resources, especially my network speed. Trying to delete/disable them only resulted in a prompt saying "Access Denied." To make things worse, I found that after a couple of hours, any browser on my computer would fail to access any site (NETWORK_ACCESS_DENIED) except usually Youtube and Google. This was fixed with restarting the computer, but the loss of access kept happening; very annoying!

 

I suspected it was the work of a rootkit and used MalwareBytes Anti-Rootkit to remove them, but they kept coming back with each reboot.

Yesterday, the Anti-Rootkit detected three pieces of malware in my AppData/Local folder that are labeled "Trojan.SmartService."

Also, I'm not able to use helpful functions on Windows 10 like "Reset my PC" or "System Restore." I would appreciate some guidance, thanks.

Hi hello_how_are_you :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.
  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
  • As long as I'm assisting you on BleepingComputer, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against BleepingComputer's rules
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread
This being said, it's time to clean-up some malware, so let's get started, shall we? :)

Follow the instructions in the thread below. Make sure to download the MBAR version linked in it. Let me know if you're not able to launch it and run a scan.

https://forums.malwarebytes.com/topic/198907-requested-resource-is-in-use-error-unable-to-start-malwarebytes/

If you manage to run a scan, delete everything it finds, and then copy/paste the content of the mbar-log-DATE-(TIME).txt log that is located in the MBAR folder here after.

And it doesn't detect the driver. Alright.

Do you have a USB Flash Drive? If so, how big is it?

Also, open FRST and copy/paste the following inside the text area. Once done, click on the Fix button. A file called fixlog.txt should be created on your desktop afterwards. Attach it here.
Start::
CMD: bcdedit.exe /set {bootmgr} displaybootmenu yes
CMD: bcdedit.exe /set {default} recoveryenabled yes
CMD: fltmc instances
CMD: dir C:\Windows\system32\drivers
End::

For the next steps, you'll need to download FRST.exe and the fixlist.txt from another computer and move them on your USB.

iO3R662.pngFarbar Recovery Scan Tool (FRST) - Recovery Environment Scan
Follow the instructions below to download and execute a scan on your system with FRST from the Recovery Environment, and provide the logs in your next reply.

Item(s) required:
  • USB Flash Drive (size depend on if you have to create a USB Recovery or Installation media)
  • CD/DVD (optional: only needed if you need to create a Recovery or Installation media and your USB Flash Drive is too small)
  • Another computer (optional: only needed if you cannot work from the infected computer directly)
Preparing the USB Flash Drive
  • Download the right version of FRST for your system:
  • Move the executable (FRST.exe or FRST64.exe) on your USB Flash Drive
  • Download the attached fixlist.txt, and move it on your USB Flash Drive as well
Boot in the Recovery Environment
  • Plug your USB Flash Drive in the infected computer
  • To enter the Recovery Environment with Windows Vista and Windows 7, follow the instructions below:
    • Restart the computer
    • Once you've seen your BIOS splashscreen (the computer manufacturer logo), tap the F8 key repeatedly until the Advanced Boot Options menu appears
    • Use the arrow keys to select Repair your computer, and press on Enter
    • Select your keyboard layout (US, French, etc.) and click on Next
    • Click on Command Prompt to open the command prompt
      Note: If you can't access the Recovery Environment using the F8 method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial on SevenForums.
  • To enter the Recovery Environment with Windows 8 or Windows 8.1, follow the instructions in this tutorial on EightForums
    Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial.
  • To enter the Recovery Environment with Windows 10, follow the instructions in this tutorial on TenForums
    Note: If you can't access the Recovery Environment using the method above, you'll need to create a Windows installation or repair media. It can be made on the computer itself or another one running the same version of Windows as the one you plan to use it on. For more information, check out this tutorial on TenForums.
Once in the command prompt
  • In the command prompt, type notepad and press on Enter
  • Notepad will open. Click on the File menu and select Open
  • Click on Computer/This PC, find the letter for your USB Flash Drive, then close the window and Notepad
  • In the command prompt, type e:\frst.exe (for the x64 version, type e:\frst64.exe and press on Enter
  • Note: Replace the letter e with the drive letter of your USB Flash Drive
  • FRST will open
  • Click on Yes to accept the disclaimer
  • Click on the Fix button and wait for the scan to complete
  • A log called fixlog.txt will be saved on your USB Flash Drive. Attach it in your next reply

Hello, Aura,
I made it to the Command Prompt, but when I enter the command, it says -This version of g:\FRST64.exe is not compatible with the version of Windows youre running. Check your computers system information and then contact the software publisher.- What should I do?

Did you download FRST64.exe from the infected computer, or another one (as instructed)?

Can you download the 32-bit version (FRST.exe) and try to run it?

Aura,

FRST64.exe worked in the Command Prompt when I named it something else! Thank goodness.

 

Here is the fixlog.txt that you needed:

Now, boot back into Windows, and run a scan with Malwarebytes.

j1Bynr2.pngMalwarebytes - Clean Mode
  • Download and install the free version of Malwarebytes
    Note: If you have Malwarebytes already installed, you don't need to install it again. Simply start from the next bullet point
  • Once Malwarebytes is installed, launch it and let it update his database. You might have to click on the little arrow by Scan Status in the middle right pane for it to do so
  • Once the database update is complete, click on the Scan tab, then select the Threat Scan button and click on Start Scan
  • Let the scan run, the time required to complete the scan depends of your system and computer specs
  • Once the scan is complete, make sure that the first checkbox at the top is checked (which will automatically check every detected item), then click on the Quarantine Selected button
    • If it asks you to restart your computer to complete the removal, do so
  • Click on Export Summary after the deletion (in the bottom-left corner) and select Copy to Clipboard. Paste the content in your next reply
