I tried installing Malwarebytes and Adwcleaner and it shows viruses have been removed but ever since I had the virus my computer keeps restarting randomly. I also tried to install Sophos but it won't even install in my computer. Can you guys please help?

Good morning @alex88

 

For the next part, you'll need to download the FRST executable from 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 shutdown, or in the Windows RE. Otherwise, the infection will mess with the files on the USB and you'll have to restart.

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)
  • 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) on your USB Flash Drive

Boot in 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 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 Windows RE, plug the USB Flash Drive in 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


Thanks

Ron

Please make sure that your USB ports are enabled and that the USB disk is bootable. I can provide a similar canned message on downloading and building the disk but you basically need to verify that your USB ports are enabled in the BIOS/UEFI

This link here gives software and explains how to make a bootable USB disk. You can do this to verify that it is bootable and once confirmed then you can format and build it with Windows 10

Hey Ron @AdvancedSetup i'm kind of lost I downloaded rufus and I have the USB stick it's a 32 GB sandisk and I saw the only option I had on rufus was "FreeDOS" so I ran that and then afterwards I copied/pasted FRST64.exe to the USB drive and then plugged it in Recovery environment and selected "use a USB device" and it just restarts and goes back to the login screen.

Here, try this method. Make sure you're using a clean computer to download and create a disk.

 

If your computer does not have the Windows Recovery Environment installed and available you can use the following method to run the Recovery Environment from a bootable USB disk.

NOTE: This USB disk needs to be created from a clean computer. You cannot use an infected computer for this process

NOTE: An 8GB USB 2.0 stick is required or at least recommended. In some cases a USB 3.0 disk can be used but some computers have issues booting from USB 3.0 disks.

Example drive (no endorsement implied, example only) - This drive example has not been tested by me. It is an older 2015 model with many good reviews though.
Amazon: Kingston 8GB DataTraveler 101 G2 USB 2.0 Flash Drive (DT101G2/8GBZ)
NewEgg: Kingston 8GB DataTraveler 101 G2 USB 2.0 Flash Drive (DT101G2/8GBZ)


STEP 1
Download a Windows 10 ISO image from Microsoft.

Method A: Using the Microsoft Media Creation Tool
https://www.microsoft.com/en-gb/software-download/windows10
Download the Media Creation Tool: https://go.microsoft.com/fwlink/?LinkId=691209

Follow the instructions displayed on the tool to download the Windows 10 ISO image.

In my testing I was not prompted for a license key to download the latest Windows 10 ISO image.
At the time of this writing 2017/12/21 there was only one ISO image offered. Windows 10

32-bit x86  or  64-bit x64

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
 

Method B: If Method A: above is not working for you then you can try the following method
Microsoft Windows and Office ISO Download Tool (this is not an authorized Microsoft tool, but appears to be legal)
https://www.heidoc.net/joomla/technology-science/microsoft/67-microsoft-windows-and-office-iso-download-tool
Download: https://www.heidoc.net/php/Windows%20ISO%20Downloader.exe

STEP 2
If you were unable to use the Windows Media Creation Tool in STEP 1 to create a USB disk then you can use this tool to burn the Windows 10 ISO image from STEP 1 above.

Download the Windows USB/DVD Download Tool from Gitbub and save to your computer.
English version: https://github.com/mantas-masidlauskas/wudt/raw/master/Downloads/Windows7-USB-DVD-Download-Tool-Installer-en-US.exe

Then install the Windows USB/DVD Download Tool and run it to burn a bootable USB disk from the ISO image. Browse to the location where you saved the Windows 10 ISO image in STEP 1
Note: This tool should work on XP, Vista, Windows 7, or Windows 10 - it is simply used to make a bootable USB disk. Remember, all of this needs to be done on a clean computer.

STEP 3
Please download the Farbar Recovery Scan Tool and save it to your desktop or other location you know where it's saved to. Then copy it to the USB disk you just created.

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

STEP 4
Shut down the infected computer. Do Not insert the USB disk you created until the infected computer has been shut down.
Once the computer is shut down then insert the newly created Windows 10 USB disk into the infected computer and power it back on and press the appropriate key to bring up the boot menu. The link below will help show you which key for various computers manufacturers is used to bring up the boot menu. Most will be either USB or UEFI depending on hardware and settings. If the computer boots up into the Normal Windows instead of the USB stick it may become infected and need to be completely redone again. Make sure you select the correct boot option.

How to Boot Your Computer from a USB Flash Drive

STEP 5
Once the computer starts to boot up from the USB disk, follow the screens and directions below.

Gvt31DC.jpg

wk8hs0E.jpg

F2gCAoF.jpg

X8NEEvb.jpg

You will need to open NOTEPAD.EXE to help find out which drive is your Windows drive and which drive is your USB disk drive you just created

O27kz3e.jpg

RRI6og4.jpg

For the more advanced user you could also use DISKPART to help locate which drive is mapped to your USB disk. In most cases the USB disk will be either ? or E: but depending on hardware the drive could be a much higher level such as H: or higher.

Example only - your hardware will look different

DISKPART> list volume
	  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     Z                       DVD-ROM         0 B  No Media
  Volume 1     C                NTFS   Partition    931 GB  Healthy    System
  Volume 2     Q   SEA-USB-4.0  NTFS   Partition   3725 GB  Healthy
  Volume 3     D                NTFS   Removable   7636 MB  Healthy


Go back to the DOS Command Prompt (if you used DISKPART type in Exit and press the Enter key) and type in the following and press the Enter key.

CD /D  ? (or E: or whichever drive letter the USB stick is on)

Then type in CD\
and press the Enter key to get to the root or top of the USB disk.

Then type in FRST   or   FRST64  (depending on which version your computer uses) and click the Scan button.

A log called FRST.txt will be saved on your USB Flash Drive. Attach it in your next reply.

If all went well you should now be able to boot into Normal Mode and run Malwarebytes and run a Threat Scan to have it finish the removal process.

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

Ron
