Hello  

I will guide you along on looking for remaining malware. Lets keep these principles as we go along.

• Removing malware can be unpredictable
• Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
• Only run the tools I guide you to.
• Do not run online games while case is on-going. Do not do any free-wheeling web-surfing.
• The removal of malware isn't instantaneous, please be patient.
• Cracked or or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
• Please stick with me until I give you the "all clear".
• If your system is running Discord, please be sure to Exit out of it while this case is on-going.

This here you can start & once it is under way, you can leave the machine alone & let it run over-night. No need to keep watch once it starts the actual scan run. 

Next, This will be a check with ESET Onlinescanner for viruses, other malware, adwares, & potentially unwanted applications.

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

 

It will start a download of "esetonlinescanner.exe"

• Save the file to your system, such as the Downloads folder, or else to the Desktop.
• Go to the saved file, and double click it to get it started.

 

• When presented with the initial ESET options, click on "Computer Scan".
• Next, when prompted by Windows, allow it to start by clicking Yes
• When prompted for scan type, Click on Full scan

Look at & tick ( select ) the radio selection "Enable ESET to detect and quarantine potentially unwanted applications" and click on Start scan button.

• Have patience. The entire process may take an hour or more. There is an initial update download.

There is a progress window display. You may step away from machine &. Let it be.  That is, once it is under way, you should leave it running.  It will run for several hours.

• At screen "Detections occured and resolved" click on blue button "View detected results"
• On next screen, at lower left, click on blue "Save scan log"
• View where file is to be saved. Provide a meaningful name for the "File name:"
• On last screen, set to Off (left) the option for Periodic scanning
• Click "save and continue"
• Please attach the report file so I can review

[schwi00]

hi!

thanks for your kind reply, so i followed the instruction above and here are the result

1.txt

[Maurice Naggar]

Thank you. That was very worthwhile, since it removed several trojans. Now, a different scan with a different tool.

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 Scan Options & select  FULL scan 

Then start the scan. Have lots of patience. Once you start the scan & you see it started, then leave it be.  

• 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 screen display.  The only things that count are the End result at the end of the run.
• Again, any on-screen display about repeat 'infection' is not to be relied on.  Ignore those.
• We only rely on the end result that is on the log-report-file.

 

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

The log is named MSERT.log  

the log will be at  

Windows\debug\msert.log

Please attach that log with your reply. We will do more later.

[schwi00]

hello again sir

 

here is the logmsert.log

[Maurice Naggar]

Well worth the effort. 

Found HackTool:Win32/AutoKMS and Removed!
Found HackTool:Win32/Keygen and Removed!
2 dodgy items removed

Now do all steps listed on this topic I'm infected - What do I do now? - Windows Malware Removal Help & Support - Malwarebytes Forums

Then attach all reports on your next reply to this thread

[schwi00]

sir I already followed the instructions of that topic and here's the result,

FRST.txtAddition.txtmalwarebytes report.txt

[Maurice Naggar]

Please do a new scan with Norton 360 & let me know the result.

[schwi00]

[Maurice Naggar]

Hi. That is a very excellent result from Norton. 

Thank you very much for the report. I would like you to start with what follows.
[ 1 ]
Do as much as possible of all the steps on this one linked-post of mine. Just keep going down the liast & do as much as you can.

Do a new scan with Malwarebytes for Windows.

Do a Check for Update using the Malwarebytes Settings >> General tab.

See this Support Guide https://support.malwarebytes.com/hc/en-us/articles/360042187934-Check-for-updates-in-Malwarebytes-for-Windows

When it shows a new version available, Accept it and let it proceed forward.  Be sure it succeeds.

If prompted to do a Restart, just please follow all directions.

Let me know how that goes.    Next, the Malwarebytes scan.

Then click the Security tab.  Scroll down and lets be sure the line in SCAN OPTIONs for

"Scan for rootkits" is ON 👈   Click it to get it ON if it does not show a blue-color .

 

Next, click the small x on the Settings line to go to the main Malwarebytes Window.   Next click the blue button marked Scan.

 

When the scan phase is done, be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

>>>>>>      👉      You can actually click the topmost left  check-box  on the very top line to get ALL lines  ticked   ( all selected).         <<<<     💢

 

Please double verify you have that TOP  check-box tick marked.   and that then, all lines have a tick-mark

 

Then click on Quarantine  button.

 

Then, locate the Scan run report;  export out a copy;  & then attach in with your  reply.

• im so sorry for the late reply sir, and here is my scan result.malwarebytes report2.txtAdwCleaner[C02].txtAdwCleaner[S02].txt

[Maurice Naggar]

Thank you. Those reports are all perfect. How is the system at this point vis-a-vis the original Norton warnings?

I would recommend getting a report on the update status of some key apps.

• Download SecurityCheck by glax24 from here  https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
• and save the tool on the desktop.
• If Windows's  SmartScreen block that with a message-window, then
• Click on the MORE INFO spot and over-ride that and allow it to proceed.

                               This tool is safe.   Smartscreen is overly sensitive.

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 in a text file named SecurityType.txt. Close the file.  Attach it with your next reply.
You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

[schwi00]

SecurityCheck.txt

well unfortunately I still get the miner bitcoin intrusions from norton, and they recommended me to run norton power eraser but again the result doesnt detect anything sir.

[Maurice Naggar]

Take these actions so that Windows 11 is set to show all hidden files and folders.
Open File Explorer from the taskbar.

Select View > Show > Hidden items.

This custom script is for  schwi00  only / for this machine only.

Be very sure to Save any work-files you have open at this point. Close & Save any open edits, if any.  

We will use FRST64  to run a custom script.    The system will be rebooted after the script has run.

This custom script has some specific things, plus some general aspect to help the system overall.  Hoping it will not exceed 60 minutes in execute time.

NOTE-1:  This script will  run a scan using System File Checker to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. .It will also run the Windows tool DISM to check Windows integrity.  It will rebuild the Winsock. 

NOTE-2: This will attempt to put 2miners onto the block section of Windows firewall.

• Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this.
• If there are any CD / DVD / or USB-flash-thumb or USB-storage drives attached,  please disconnect any of those.
• Please save the (attached file named) FIXLIST.txt   to the   E:\Download\programs   folder

Fixlist.txt          <<< - - - - -

Then, Start the Windows Explorer and then, go  to the E:\Download\programs  folder.

RIGHT click on FRST64  and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
IF Windows prompts you about running this, select YES to allow it to proceed.

• IF you get a block message from Windows about this tool......

               click line More info information on that screen
               and click button Run anyway on next screen.

• on the FRST window:

Click the Fix button just once, and wait.

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. 
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your next reply later, at your next opportunity.

[schwi00]

heres the result sir, I've done what you instructed me above.Fixlog.txt

[Maurice Naggar]

Very good run. How is the system now?

[schwi00]

unfortunately it still popping up sir,

[Maurice Naggar]

I would like a report set for review.   This is a report only.

Please download MALWAREBYTES MBST Support Tool

Once you start it click Advanced >>> then   Gather Logs

 Have patience till the run has finished.

Upload an archive once it is done. Attach the mbst-grab-results.zip from the Desktop.

 

• Please attach  mbst-grab-results.zip    to your reply 😀

[schwi00]

here you go sir,

[Maurice Naggar]

Thanks for the report. What follows is intended to be a scan of the whole drive C by Malwarebytes.
First, you want to de-clutter the desktop views by closing as many screens as you can beforehand.
Launch Windows File Explorer. Look on the left-side frame to where "This pc" is listed.
Expand that by clicking on it once.
Now look for the drive C:
Using mouse, do a RIGHT-click on C: and select

Scan with Malwarebytes

. This should start Malwarebytes. It may take a bit for the on-screen GUI display. Have patience.
Let me know the result.  Locate the Scan run report;  export out a copy;  & then attach in with your  reply.

Sir, here is the result of my disk C scan,

[Maurice Naggar]

Alright. 

Let's check your system with another ( different ) antivirus scan tool.

Please download and run the following Kaspersky Virus Removal Tool 2020 and save it to your Desktop.

(Kaspersky Virus Removal Tool version 20.0.10.0 was released on November 9, 2021)

Select the    Windows Key and R Key together, the "Run" box should open. Drag and Drop KVRT.exe into the Run Box. C:\Users\{your user name}\DESKTOP\KVRT.exe will now show in the run box. add -dontencrypt   Note the space between KVRT.exe and -dontencrypt C:\Users\{your user name}\DESKTOP\KVRT.exe -dontencrypt should now show in the Run box.   That addendum to the run command is very important, when the scan does eventually complete the resultant report is normally encrypted, with the extra command it is saved as a readable file. Reports are saved here C:\KVRT2020_Data\Reports and look similar to this report_20210123_113021.klr Right-click direct onto that report, select > open with > Notepad. Save that file and attach it to your reply. To start the scan select OK in the "Run" box. A EULA window will open, tick all confirmation boxes then select "Accept" In the new window select "Change Parameters" In the new window ensure all selection boxes are ticked, then select "OK" The scan should now start... When complete if entries are found there will be options, if "Cure" is offered leave as is. For any other options change to "Delete" then select "Continue" When complete, or if nothing was found select "Close" Attach the report information as previously instructed... Sincerely.
