Potential Malware Infection


Moe2572

Recommended Posts

Hey and good morning.

I believe I might be infected with malware. Unfortunately my system stability has gone off the rails the last week or so with random blue screens (windows 10), and/or my chrome/applications randomly crashing. My malwarebytes has also been crashing randomly, and there are times where my malware/web protection are turned off. After turning them back on, my malware protection turns back on, and my web protection remains turned off no matter what I do. I've tried to complete MBcheck and MBclean/re-installing malwarebytes two times now, using the procedure highlighted here, with the problem persisting unfortunately. I've attached my most recent threat scan, FRST/Additions files, please let me know if any other info/details are needed from me.

Thanks in advance,

Moe

Hello Moe2572 and welcome to Mlawarebytes,

Continue with the following:

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:
    Potentially Unwanted Programs (PUP`s) set as :- Always detect PUP`s (recommended)
    Potentially Unwanted Modifications (PUM`s) set as :- Alwaysdetect PUM`s (recommended)
     
  • 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
  • If asked to restart your computer to complete the removal, please do so
  • 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:
 
  • Click on the Reports tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

     
  • Use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…


Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select user posted imageRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Clean button. This will kill all the active processes
  • 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

Ensure to get the correct version for your system....

https://www.microsoft.com/en-gb/download/malicious-software-removal-tool-details.aspx


Right click on the Tool, select “Run as Administrator” the tool will expand to the options Window
In the "Scan Type" window, select Quick Scan
Perform a scan and Click Finish when the scan is done.


Retrieve the MSRT log as follows, and post it in your next reply:

1) Select the Windows key and R key together to open the "Run" function
2) Type or Copy/Paste the following command to the "Run Line" and Press Enter:

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 reply, also Zip up and attach this folder C:\WINDOWS\Minidump

Thank you,

Kevin...

Hi Kevin and thanks so much for getting back to me quickly, I've attached each of the logs after completing these scans. Just have a couple points to bring up I noticed during the cleaning:

  • My malwarebytes is still crashing at random times unfortunately, and while my malware protection can be turned on, my web protection stays turned off (can't turn it on at all).
  • When completing the microsoft malicious software removal tool, at one point I noticed hundreds of files being found as infected, but when the cleaning finished the search came up with no infections whatsoever (and nothing to quarantine)

So unfortunately even after completing the above steps it seems like I may still be infected.

 

Thanks again for all of your help and let me know if there are any next steps I can continue taking.

Thanks as always,

Moe

Hi Kevin,

Will do, unfortunately I'm at work all day and won't be able to update you until later tonight.

Just to note, I did run the FRST fix list and followed your procedures from start to finish. I'll be sure to send you the log when I get home later tonight.

 

Thanks again for all of your help,

Moe

Thanks for your patience Kevin. I just re-ran everything and attached the associated logs.

These issues still persist:

  • My computer will crash/blue screen, after restarting my web-protection stays permanently off regardless of what I do. I'll use MB-clean once my malwarebytes starts to have issues, and it holds up for a random amount of time before happening again.
  • Microsoft Malicious software remover finds four infected files while searching, completes it search, and turns up no infected files found and/or cleaned.

 

Thanks and let me know if there is anything else I can attach/send you (re-attached the minidump as a zip).

The zipped mini dump folder is empty, can you navigate here: "C:\Windows\Minidump" open that folder and check if there are any files inside... As you are suffering with BSOD I need to see those mini dump files to check if there is a driver causing the problem....

Regarding Malwarebytes, the best way forward to try and cure the web protection issue is a fresh install..

Not sure why MRST should indicate infected files during its search but subsequently nothing in its log... Probably need to run a more indepth scanner for comparison....

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....

Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....



The Virus Removal Tool scans the following areas of your computer:
  • Memory, including system memory on 32-bit (x86) versions of Windows
  • The Windows registry
  • All local hard drives, fixed and removable
  • Mapped network drives are not scanned.



Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs

Thanks,

Kevin...

Hi Kevin,

Thanks for putting up with the long wait to respond, workdays have been extra long due this week.

It seems the reason I've been unable to zip these minidumps is lack of permission. I haven't had an accessibility issue until now, as my account is also the system administrator. I'm really confused about that, even when checking permissions, I should have the ability to make the files read/copyable, but am unable to do so:

Screenshot of what I'm running into. Let me know if you have any ideas.

 

I'm running the sophos virus scan right now, should have an update for you tomorrow morning hopefully.

Hello Moe,

The BSOD are attributed to a Malwarebytes driver, lets make a clean install and see if the BSOD issue ceases..

Totally Remove Malwarebytes from your system:

Download the latest version of Malwarebytes cleanup tool from here: https://downloads.malwarebytes.com/file/mb_clean and save to your Desktop..

If applicable, backup your Malwarebytes license key information and deactivate the product.

Close all open applications and deactivate Malwarebytes <---- Very important, do not miss that step

To deactivate Malwarebytes:

Right click on tray icon, from the opened list select "Quit Malwarebytes" an UAC alert will open, select "Yes" to deactivate Malwarebytes...
 
  • Double-click mb-clean.exe to run it
  • A prompt to confirm the cleanup will appear, select Yes or No
  • Yes - will proceed with the cleanup process <---- Select this option to start the tool
  • No - will exit the utility
  • The Utility will launch a Command Prompt window which will disappear once the the cleanup process completes.
  • Once completed, a log file ("mb-cleanresult.txt") will be on your desktop and you'll be prompted to reboot
  • We recommend an immediate reboot <--- Do Not miss out this step
  • Suppressing the reboot may result in an incomplete cleanup
  • Upon reboot Malwarebytes will be totally removed from your system


To re-install Malwarebytes:

Download Malwarebytes version 3 from the following link:

https://www.malwarebytes.com/mwb-download/thankyou/
 
  • Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....
  • When the install completes and is updated do the following:
  • Open Malwarebytes, select > "settings" > "protection tab"
  • Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....
  • Go back to "DashBoard" select the Blue "Scan Now" tab......



When the scan completes deal with any found entries... Then select "Export Summary" then "Text File (*.txt)" name that log and save , you can copy or attach that to your reply...

Let me see the log from Malwarebytes, also let me know if the BSOD issue has ceased...

Thank you,

Kevin..
