Hello, I attach the requested files

Adición.txtFRST.txt

[AdvancedSetup]

Please run the following cleanup script.

 

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Note: If the tool warned you about an outdated version please download and run the updated version.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
• Flash Player 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.

I attached the requested fileFixlog.txt

[AdvancedSetup]

Please run the following.

 

STEP 01

• If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
• If you don't have Malwarebytes installed yet please download it from here and install it.
• Once installed then open Malwarebytes and select Scan and let it run.
• Once the scan is completed make sure you have it quarantine any detections it finds.
• If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Double-click to run the program
• Accept the End User License Agreement.
• Wait until the database is updated.

Hello, I have completed the 2 steps, I attach the results:

 

- MalwareBytes Scan Result : escanearResultados.txt

- AdwCleaner Scan Result: Limpiador de Anuncios[S01].txt

 

Thank you very much for your help, I look forward to the next indications

[AdvancedSetup]

Let's go ahead and scan this with another scanner from Microsoft.

 

 

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.

Thank you

 

[alezdsgs]

I attached the requested filemsert.log

[AdvancedSetup]

Okay. That looks good too. Thanks for the log.

 

Not sure why at this point that the anti-rootkit tool would have logged a detection. Please go ahead and try the tool again by following the directions from this post

 

[alezdsgs]

Hello, good evening, I followed the steps until I performed the rootkit scan and no more errors appeared.

 

at no time did the error window appear.

Should I consider that my files have already been fixed? Or do you recommend me to do some more steps?

 

Thank you very much for your help, I look forward to your response

[AdvancedSetup]

Based on our current scans I do not see any issues. Let's go ahead though just for clarity and run another antivirus scanner to double-check.

Please temporarily disable any real-time protection from antivirus and exit out of Malwarebytes and run the following.

 

 

Let me have you run a different scanner to double-check. I don't expect it to find anything, but no harm in checking.

I would suggest a free scan with the ESET Online Scanner

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 the 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 should ignore all prompts to get the ESET antivirus software program.   ( e.g. their standard program).   You do not need to buy or get or install anything else.
• When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.
• Click The blue “Save scan log” to save the log.
• If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at the bottom).
• Press Continue when all done.  You should click to off the offer for “periodic scanning”.

 

Note: If you do need to do a File Restore from ESET please follow the directions below

[KB2915] Restore files quarantined by the ESET Online Scanner version 3

https://support.eset.com/en/kb2915-restore-files-quarantined-by-the-eset-online-scanner

 

[alezdsgs]

Thank you very much for your help, I did the steps you indicated and did not find any threat, I attach the log file

eseScan.txt

 

 

Do you advise me to do another check?

[AdvancedSetup]

No, the computer is not showing any signs of an infection at this time.

 

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.
• Please attach that file to your next reply. (not compulsory)
