Hello, I'm hoping someone on the support team can help me. It appears like I'm getting a similar experience as this thread: 

 

I downloaded and installed something I wish I never had. Ever since I have uninstalled it but these 13 traces of Trojan.BitCoinMiner detections keep coming back after about 2-3 days.

I have since run adwcleaner and the Farbar tool after looking at a previous thread about this issue. However, that tool needs a specific fix file created by someone so I was hoping someone could help me with that and what process they want me to go through.

Thank you in advance!

Hello  and  :welcome:      @E23

 

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 uninstall the following via the Control Panel

Bonjour
 

 

 

The act of torrenting itself is not illegal. However, downloading and sharing unsanctioned copyrighted material is illegal, and there is always a chance of prosecution if caught by the authorities.
Torrenting non-copyrighted material is perfectly fine and is allowed. However, be aware that we have seen increased malware bundled with software downloads over P2P.

Recent Ransomware infections have been seen to encrypt user data so that no one can decrypt the data without the private key.
When sharing files, please keep in mind that you're increasing your system's attack surface area, which can increase the risk of infection.

Scan all files before running them. https://www.virustotal.com

If you don't need or use the P2P software, you should uninstall it. It can be quite dangerous to your system and data.

Please run the following fix, once the fix has been completed, please attach the FIXLOG.TXT file to your next reply

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, 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.

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.

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) or wherever you ran FRST from. 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.

NOTE-1:  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. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: 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 will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: 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.

Thanks

Thank you for the log @E23

Can you please locate and upload the following zip file that was created on your desktop

C:\Users\erice\Desktop\27.09.2022_08.16.08.zip

 

Then run the following scan

 

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.

Hi AdvancedSetup,

It seems like it is gone now. I ran a new MalwareBytes scan and it came up with no detections. But I will certainly report back in the 2-3 days it would usually come back during.

I forgot to mention before I was getting this random blue command prompt looking window every 20 minutes or so after a boot up when the Trojan was in action. But I'm happy to report I haven't seen it happen since finishing these scans. After the Windows Security tool ran, my PC rebooted and it began Scanning and repairing disk errors for drive C and got stuck at 100%.

Thanks so much again, feels good to know most likely this pest is gone now.

Great, glad to hear, please run the following @E23 I'll check back on you again tomorrow

 

 

SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"  and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

Thank you again for all your help and the tips you provided. I have attached the file you have requested.

Also I want to just say it's been a bit difficult sometimes to reply back here because the spam filter keeps saying it's detected a spam like response and I try to reword it but it doesn't work. Hopefully this line here will make it submit my reply.

Yes, sorry about that. Due to a high content of SPAMMERS we have to run an aggressive spam filter that can also produce false positive.

The good news though is we're done here. Your system should be clean now and if you follow the advice above and setup good system and data backups you should be much better off for the future.

Take care and stay safe out there. @E23
