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.

thank you so much!

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.

it took a while to run it but its done-
for some reason it crashed few time until i tried to run it through a safe mode and then it worked but it took around 18 hours to finish
anyhow its done

i've noticed that all the files that were detected and elimnated by msert are from a long time ago when i just bought this setup from second hand.

thanks

As a next step, I suggest the following:

This is for a scan with ESET Onlinescanner (free). ESET is a well-respected, well-known entity and tool.

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 occurred 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

[Maurice Naggar]

AFTER the completion of the scan by ESET Onlinescanner, these are the next steps.
(1)

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center

Click the Security Tab. Scroll down to

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".
{ We want that to be set as Off   .... be sure that line's  radio-button selection is all the way to the Left.  thanks. }

This will not affect any real-time protection of the Malwarebytes for Windows    😃.

Close Malwarebytes.

(2)

Please run the following custom script. Read all of this before you start. Please Close all open work.

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

Farbar program :  is FRST64.exe

Please download the attached fixlist.txt file and save it to C:\Users\dized\Downloads

Fixlist.txt

 

NOTE. It's important that both files, FRST64, and fixlist.txt are in the same location or the fix will not work.

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.

Use File Explorer to go to the Downloads folder

RIGHT-Click on   FRST64 and select

RUN as Administrator

and reply YES to allow it to go forward to start.

That is important so that this run has Elevated Administrator rights !!

NEXT 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 Downloads folder (Fixlog.txt) . 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 scans with MS Defender antivirus. Depending on the speed of your computer this fix may take 40 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. 

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
• 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. Attach FIXLOG.txt with net reply.

Hey! here are the two logs

by the way - do i need to add  another security to my pc besides Malwarebytes? i had kaspersky before but i got notification from it saying they are colliding or something like it

Thank you so much

Fixlog.txt esetscanlog.txt

[Maurice Naggar]

ESET Onlinescanner found and removed some potential threats.
The Fix run is good. System File Checker /Windows Resource Protection found corrupt files and successfully repaired them.

You mentioned Kaspersky, however that is not shown as currently installed. As far as antivirus protection, the Microsoft Defender antivirus is fully on and up-to-date. It works well alongside Malwarebytes. Do you have the Premium license for Malwarebytes ?

This next report will provide a report as to the security apps that are on this machine, as well as tell us if there are out-of-date applications.

( Run report on security state )

Temporarily disable Microsoft SmartScreen to download the next software below 

I would recommend getting a readout report as to update status of some key apps.
Download SecurityCheck by glax24 from here

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

When all done, you may go back to turn ON the EDGE Smartscreen protection.

[dimitrius]

before i've upgraded to win 11 i had kaspersky but it always showed a message that they are colliding or something like this so i decided to turn off the subsription because malware bytes always alert sooner then kaspersky and i felt more safe with him.

yes i've been using the premium the last 3-4 years and im really happy with it!

securitycheck.txt

[Maurice Naggar]

SecurityCheck reports only 1 application needing attention. This one you should consider to Uninstall
Vuze v.5.7.7.0  Warning! Ad-supported P2P-client

As far as Malwarebytes notice-windows or flagged items, are all the original issues now all gone?

Malwarebytes protections are running side-by-side along with MS Defender antivirus. It seems to me this machine is good-to-go.

[dimitrius]

Done uninstalling! 

yeah everything runs perfectly!
when you've asked me to disable the screenprotection app i accidently pressed "off" and now i realize that i can't turn it back on :D  (for the security check)
is this a huge problem? or can i live without it? 

anyway thank you a lot! that was incredible! 

[Maurice Naggar]

Good. as to turning Smartscreen protection back ON, see this article
https://www.elevenforum.com/t/enable-or-disable-microsoft-defender-smartscreen-check-apps-and-files-from-web-in-windows-11.5731/

see OPTION ONe  use the "Turn ON" segment  ( toggle to the far right to turn on )

Let's go ahead and do some clean-up work and remove the tools and logs we've run.
Please download KpRm by kernel-panik and save it to your desktop.

• right-click kprm_(version).exe and select Run as Administrator.
• Read and accept the disclaimer.
• When the tool opens, ensure all boxes under Actions are checked.
• Under Delete Quarantines select Delete Now, then click Run.
• Once complete, click OK.
• A log will open in Notepad titled kprm-(date).txt.
• You may attach that file to your next reply. (not compulsory)
  

Sincerely.

[dimitrius]

done!
