Hi,

I'm one of MalwareBytes fans, my computer got infected by some malicious hidden Malware Ads. Everytime my computer connect to Internet, my computer got lag. I've tried several times scanning/repair this using Malwarebytes, AdwCleaner, and Mbar but the virus/malware keep coming back. Would you mind to help me??? :)

Here is Scan log from Farbar tool Recovery

Hello @Gaku

You're using Windows Defender Controlled Folder Access. You may need to disable that while we work on cleaning up your computer.

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

  • If you're already running Malwarebytes then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • If you don't have Malwarebytes installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and select Scan and let it run.
  • Once the scan is completed click on the View Report button, then the Export button and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know in your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Right-click on the program and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the Terms of use.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, please click Clean & Repair.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Attach or Copy its content into your next reply.

 

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a checkmark here.
  • Please attach the Additions.txt log to your reply as well.

 

Thanks

Okay, you have a few issues going on that I believe are probably stepping on each other. Let's do some general clean up and then we'll do some other scans to make sure there are no issues.

1. Please run the Avast removal utility 
2. Go in to Control Panel, Programs, Add/Remove and uninstall the following software at least temporarily

CCleaner
HitmanPro 3.8
IObit Unlocker
ProtonVPN
ProtonVPNTap
SMADAV
SUPERAntiSpyware

 

3. Then, turn OFF the Windows Defender Controlled Folder Access

Once you've completed the steps above please restart the computer one more time and run FRST again. Make sure you get NEW logs for FRST and ADDITION.txt and post those logs and we'll see what other remaining issues you may have.

Hello @Gaku

Sorry for the delay. Please try the following fix

 

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

fixlist.txt

Thanks

For the next part, you'll need to download the FRST (executable on a clean computer and move them onto your USB Flash Drive. That USB can only be inserted in the infected computer if it is either shut down or in the Windows RE (Recovery Environment). Otherwise, the infection will mess with the files on the USB and you'll have to restart all over again.

Be very careful and press and hold the SHIFT key down while inserting the USB stick. If it auto launches the infection will damage the file on the USB stick and you'll need to format it and start over again.

 

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 depends on if you have to create a USB Recovery or Installation media)
  • Another computer (clean of infection)
  • CD/DVD (optional: only needed if you need to create a Recovery or Installation media and your USB Flash Drive is too small)

Preparing the USB Flash Drive

  • Download the right version of FRST for your system from a clean computer:
    • FRST 32-bit
    • FRST 64-bit
      Note: Only the right version will run on your system, the other will throw an error message. So if you don't know what your system's version is, simply download both of them, and the one that works is the one you should be using.
  • Move the executable (FRST.exe or FRST64.exe) onto your USB Flash Drive

Boot into the Recovery Environment

  • To enter the Recovery Environment with Windows Vista and Windows 7, follow the instructions below:
    • Restart the computer
    • Once you've seen your BIOS splash screen (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 the 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 Windows RE, plug the USB Flash Drive into the computer

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 Scan button and wait for the scan to complete
  • A log called FRST.txt will be saved on your USB Flash Drive. Attach it in your next reply

Excellent. From the log file it shows that the main files we were trying to remove were removed for us.

"HKLM\System\ControlSet001\Services\{45487F67-EC9F-4449-A6F2-2D0970F9B80B}" => removed successfully
C:\Windows\System32\drivers\Wdf07811.sys => moved successfully

Please remove the USB stick if it's in it. Then go ahead and restart the computer into NORMAL Mode and run FRST again and post back both new logs.  FRST.txt and ADDITION.txt

Great, that looks good too now.

Can  you please run this last fix. It will zip up the quarantine folder and make a zip file on your desktop with the current Date and Time. Please attach that file on  your next reply so that I can review the actual files that infected the computer.

 

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.
