Hi all-

I got infected with malware and im having a struggle trying to remove the last remnants of the malware/viruses.  Ive tried multiple apps, but have not been successful.  

 

I'm having a similar problem as this user: 

Ive tried mbar, adw, roguekiller, scanned with FRST, but nothing has worked.  Please help!

Hello DavidCar and welcome to Malwarebytes....

See if you can follow these instructions:

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 USB Flash drive (memory stick)..

NOTE: This USB USB Flash drive (memory stick). needs to be created from a clean computer. You cannot use an infected computer for this process

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

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 USB Flash drive (memory stick)., follow the screens and directions below.

You will need to open NOTEPAD.EXE to help find out which drive is your Windows drive and which drive is your USB  ,USB Flash drive (memory stick).you just created

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 D: 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  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.


Let me see those logs,

Thank you,

Kevin....

Hello DavidCar,

Thanks for those logs, leave your PC in Normal mode and continue as follows:

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Open Malwarebytes Anti-Malware.
 
  • On the Settings tab > Protection Scroll to and make sure the following are selected:
    Scan for Rootkits
    Scan within Archives
     
  • Scroll further to Potential Threat Protection make sure the following are set as follows:

  • Click on the Scan make sure Threat Scan is selected,
  • A Threat Scan will begin.
  • When the scan is complete if anything is found make sure that the first checkbox at the top is checked (that will automatically check all detected items), then click on the Quarantine Selected Tab

  • When complete click on Export Summary after deletion (bottom-left corner) and select Copy to Clipboard.
  • Wait for the prompt to restart the computer to appear, then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more to retrieve the log.


To get the log from Malwarebytes do the following:

  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download Microsoft's " Malicious Software Removal Tool" and save direct to the desktop

notepad c:\windows\debug\mrt.log

The log will include log details for each time MSRT has run, we only need the most recent log by date and time....

Let me see those logs in your next reply, also tell me if there are any remaining issues or concdern....

Thank you,

Hi Kevin-

The system showed the virus removed after the recovery process and the subsequent malware scan showed 2 registry keys that remained.

When I attempted to run the FRST w/ the fixlist.txt file the computer restarted and initiated an update process.  Every subsequent time i ran the FRST it would say a tmp file was missing.  Then i noticed the malware came back in a different file name.  I again ran the steps you provided and i've attached the log named "FRST2" and "malwarelog2".  Can we try once more for a fixlist?  Thank you again for your time and your help

mmmm, I`m wondering if this infection has mutated yet again....

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Ok-

Here's what happened:

Put fixlist.txt into the desktop with the FRST64 app.  Opened FRST.  It updated, then said "Windows cannot find 5DC6.tmp.exe Make sure you typed the name correctly, and then try again.", i cliked OK- then the system immediately restarted without me clicking Fix AT ALL.  Every subsequent time I try to run FRST, i get a different filename that is "missing" 4ECD.tmp.exe, D88E.tmp.exe.  After the restart I've noticed this suspicious app is running "pskdtarsvc" and resists my attempts to "end task"

Ok, The best way round this infection is to Boot the sick PC to the recovery environment and leave it there.....

Next,

Plug your Flash drive into the laptop and carry out Quick format...... When that completes upload FRST to the flash drive. https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

With sick PC in RE continue as follows:

user posted image


From that window select "Troubleshoot"


user posted image


From the next window select "Advance Options"


user posted image


From that Window select "Command Prompt"

Ensure to plug the flash drive into a USB port... You should now be in Recovery Environment with the Command Prompt Window open......

Continue with the following:
 
  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" or "My PC" and find your flash drive letter and close the notepad.
  • In the command window type E:\frst64 or E:\frst depending on your version. 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.
  • It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

Leave sick PC in RE mode, bring flash drive back to laptop and post its log.....

When I see that log i`ll work out another fix to run through RE mode again...
