While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

  1. Please do the following so that we may take a closer look at your system for any possible infections.

  2. WARNING: Do Not click the Repair System under Advanced unless requested to by a Malwarebytes support agent or authorized helper
  3. NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  4. Download the Malwarebytes Support Tool
  5. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  6. In the User Account Control pop-up window, click Yes to continue the installation
  7. Run the MBST Support Tool
  8. In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  9. In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  10. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please upload that file on your next reply
     

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have sent.

Thank you.

Hello  and  :welcome:    @EricZ

 

My screen name is AdvancedSetup and I will assist you with your system issues.
 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow all steps in the provided order and post back all requested logs
  • Please attach all log files to your post, unless otherwise requested
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
  • Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
  • Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim.
  • Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections.
  • If there are any on the system you should uninstall them before we proceed.
  • Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
  • If your system is running Discord, please be sure to Exit it while this case is ongoing.

 

Please run the following.

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well
 

STEP 1

Please set File Explorer to SHOW ALL folders, all files, including hidden ones.  Use OPTION ONE or TWO of this article

https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

  • Once you see it has started, take a long long break;  walk away.  Do not pay credence if you see some intermediate early flash messages on the screen display.  The only things that count are the End result at the end of the run.
  • The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

It is normal for the Microsoft Safety Scanner to show detections during the scan process.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

Then it writes into the log on your computer what it found.

 

Thank you

Next, after the Microsoft run, please run the following fix @EricZ

 

NOTE: Please read all of the information below before running this fix.

  • 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 that cannot be undone.

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   FRSTEnglish.exe

Save the attached file:  FIXLIST.TXT to this folder C:\Users\info\Downloads\

NOTE. It's important that both files, FRSTEnglish.exe, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

 

 

Run the Farbar program with Admin rights and press the Fix button just once and wait.

The fix may possibly take up to 60 minutes to complete

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 named Fixlog.txt in the same folder you ran the Farbar program from. Please attach that log on your next reply.

 

  1. NOTE:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity.
  2. NOTE: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications may be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed in most, but not all cases.
  3. NOTE: As part of this fix, it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Discord cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

fixlist.txt

Thanks

I'm sorry @EricZ but I have some bad news. Checking closer at your logs your system is infected with the Neshta.Virus

The best thing to do is back up your personal data, no system files.

Then reinstall Windows

 

Clean Install Windows 10 & 11 (2023)

Yes, any drive that is/was connected will be at risk.

Only backup files like images, office documents, videos, etc. No programs, no executables, etc.

The virus itself can be removed but not the damage done to all the executable programs
