Recommended Posts

Hello @Acor and welcome back:

In addition to the logs requested below, please add what indications or behavior leads you to believe the computer is infected

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. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
  6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
  7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

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.

Need help Microsoft Windows Defender and Malwarebytes didn't detect anything

Hello :welcome:  @Acor My name is Maurice. I will guide you.

If possibly you have a browser issue, can you try using a different web browser?
But in any event, always SAVE the downloads I guide you to. Then after download is complete, you go to the file using File Explorer.
and only then, launch it from there.

Let's do one special run  with Malwarebytes Adwcleaner. 
 
It will not take much time, Read over all lines before starting so that you have a good understanding of the whole method. Take your time and go careful. I ant to make sure you select all of what I list below - before- pressing the "scan" button.
 
First download & save it
 
Then go to where the EXE file is saved. Start Adwcleaner.  Do not rush. There are a few first choices to set as I have listed below.
 
Reply YES at the Windows prompt to allow the program to proceed and make changes. That is the usual Windows security prompt.
 
When AdwCleaner starts, on the left side of the window, click on “Settings” and then enable these repair actions on that tab-window
by clicking their button to the far-right for ON status
Delete IFEO keys
Delete tracing keys
Delete Prefetch files
Reset Proxy
Reset IE Policies
Reset Chrome policies
Reset Winsock
Reset HOSTS file
 
ADW-s-1.png.c32838f45f840beb2b835ad51f0a1b7c.png
 
 
ONLY after you have set the selections above ....only after that .....
Now On the left side of the AdwCleaner window, click on “Dashboard” and then click “Scan” to perform a computer scan.
 
 
This can take several minutes.
When the AdwCleaner scan is completed it will display all of the items it has found. Click on the “Quarantine” button To remove what it found.
 
AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.
Click on the “Continue” button to finish the removal process.
 
 
 
Attach the clean log from Adwcleaner when all completed. For example AdwCleaner[C00].txt. This is just a first-step measure.

What about the games? Are they obtained from the original publisher and paid for ?

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

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  CUSTOM scan  & then select the C drive to be scanned.

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.

Yes I paid for them. I will try to run the Microsoft Safety Scanner again tomorrow. I already tried it but it won't launch. I already tried to troubleshoot it using the guide from microsoft but it won't work

When wanting to make a Reply, you do not need to press the "quote" spot. Just go directly to the white reply spot at the bottom. 

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 CUSTOM scan  and select C drive to be scanned
  • 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

Now a different scan with another security scanner. 

This with Kaspersky KVRT tool.

Download Kaspersky Virus Removal Tool (KVRT) from here: https://www.kaspersky.com/downloads/thank-you/free-virus-removal-tool and save to your Desktop.

Next, Select the Windows Key and R Key together, the "Run" box should open.

add
-dontencrypt

Note the space between KVRT.exe and -dontencrypt

C:\Users\Windows\DESKTOP\KVRT.exe -dontencrypt 

should now show in the Run box.

That addendum to the run command is very important.


To start the scan select OK in the "Run" box.



The Windows Protected your PC window "may" open, IF SO then select "More Info"

The Kaspersky tool is very thorough so will take a considerable time to complete, please allow it to finish. Also while Kaspersky runs do not use your PC for anything else..

  • completed: If entries are found, there will be options to choose. If "Cure" is offered, leave as it is. For any other options change to "Delete", then select "Continue".
  • Usually, your system needs a reboot to finish the removal process.
  • Logfiles can be found on your systemdrive (usually C: ), similar like this:

Reports are saved here C:\KVRT_data\Reports and look similar to this report_20230310_103000.klr

  • Right click direct onto those reports, select > open with > Notepad.
  • Save the files and attach them with your next reply

Neither ESET Online or Kaspersky KVRT are "installed". They are free-standing executables. They will be removed by the following cleanup tool.
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)

Delete mb-support-1.8.7.918.exe
Delete mbst-grab-results.zip on the Desktop. 

Normally, one does not need a "download manager". Not if you are a typical home computer user.
If you think you gotta have one, this is a paid-for app you may consider https://www.internetdownloadmanager.com/

That is right, I do not see a actual infection here, except for a restriction on Windows Update. Yes the download manager I mentioned is safe. And I mentioned it is a paid program.

To do this next script you can simply download & save a new copy of the tool FRST64.exe and insure to save it to Downloads folder

from this link https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/dl/82/

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\Windows\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 custom script 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 reset the Winsock. It will attempt to help with Windows Update. It will attempt to clear all Cache and history on web browsers. Depending on the speed of your computer this fix may take 40-50 minutes or more.

The system will be rebooted after the fix has run. Attach FIXLOG.txt with next reply.

Thanks for the log. As to the app you mention, I have no direct knowlege of it and no experience of it either.
I would say not to rush into that. To wait a good while to see how things go over next week or so.
And to focus more on the tips here:
See https://support.microsoft.com/en-us/help/2746761/how-to-speed-up-your-slow-computer

also, at Bleepingcomputer

https://www.bleepingcomputer.com/forums/t/87058/slow-computerbrowser-check-here-first;-it-may-not-be-malware/

I would highly suggest to insure that this pc is all up-to-date with security updates & cumulative updates on Windows. select the Windows Start  button, and then go to Settings  > Update & Security  > Windows Update . and click Check for Updates.
Have much patience.

Thank you for the help!

When I scan using eset online scanner and kaspersky kvrt I forgot to view hidden files, is that okay?

That is OK. No need to fret. To recap, so far, I had you run Adwcleaner, ESET Onlinescanner, Kaspersky KVRT, plus a custom fix-script.

I also would appreciate this report:

Download   Farbar's Service Scanner utility

and Save to your Desktop.

Right-Click on fss.exe and select Run As Administrator.

Answer Yes to ok when prompted.

If your firewall then puts out a prompt, again, allow it to run.

Once FSS is on-screen, be sure the following items are check-marked:

  • Internet Services
    Windows Firewall
    System Restore
    Security Center/Action Center
    Windows Update
    Windows Defender
    Other services

  

Click on "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.   Please attach that file.  

( 2 )

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

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).         <<<<     💢

 

MB4_scan_tick_ALL.jpg.d5c4071c62ed66534301fbb217b93bc0.jpg

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.

MB4_scan_all_Quarantine2.jpg.6c45445994d4125c0b617ac7c5551e03.jpg

 


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

Hello. Thank you; the FSS report is very good. Now then, the Malwarebytes scan of 12 March reported no malware.
Prior to that, there were scans by Kaspersky KVRT & ESET Onlinescanner, as well as Adwcleaner. Plus we have done a custom-script fix run.
I believe your system is good-to-go.
I would highly suggest to insure that this pc is all up-to-date with security updates & cumulative updates on Windows. select the Windows Start  button, and then go to Settings  > Update & Security  > Windows Update . and click Check for Updates.
Have much patience.
