Got it.  Thank you.

[    1    ]

As a next basic step, 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

[    2    ]

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.

Now Close   ( exit ) Malwarebytes.

[    3    ]

This njext scan can take several hours.  Much patience is called for.

Thank you.

Now a fresh new scan with Malwarebytes for Windows.

  •  
  • Click Settings ( gear icon) at the top right of Malwarebytes window. We want to see the SETTINGS window.
  •  
  • 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).         <<<<     💢

Thank you.   I suggest we do one additional scan.

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 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.

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 bottom).

Press Continue when all done. You should click to off the offer for “periodic scanning”.

Please make sure you attach the log report.

OK.  Thank you.   Lets make time to do a Full scan with the Microsoft Defender antivirus.   Know that this can take many hours.

This is one way to do a manual scan using the Microsoft Windows Defender antivirus.
From the Start menu, select Settings, then select Update and Security.
Next, look at the left-side menu & select Windows Security
 

image.png.53b8290f51fb52ad1f67f2be5d1a7198.png

 

Next, In Windows Security section:  Click on the grey button Open Windows Security

 

Now, click on the shield Virus and threat protection

By the way, when you see a green check-mark on your display, it means a good status  and that  protection is on. 

image.thumb.png.d3c40d161bda6630f463e83ce53f9782.png

 On the next display,  look at all the options.   Look down the list and see "Check for Updates" which I have highlighted with a blue icon.

You can click on that to have the system check for updates for Windows Defender.

Please also note that the Scan options (all) can be displayed by clicking on Scan options.  ( You can do Quick, Full, or Custom).

Click SCAN Options button  >>   Select

FULL scan

There is a bit more work to do.  I had noticed a few files that need rechecking which looked suspicious.

This custom script will do that.  It will also do one quick scan with Microsoft Defender just to be sure.  I expect this ought to be not more than 45 minutes in total.

It is worth doing.

Please save the (attached file named) FIXLIST.txt   to the   DOWNLOADS folder

Fixlist.txt

 

The custom script on this post is ONLY for this machine and NO other.   

  • 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.

 

The system will be rebooted after the script has run.

 

 

  • Start the Windows Explorer and then, to the   Downloads folder.
  • RIGHT click on  FRSTENGLISH.exe   and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow 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.

 

frst-fix.jpg.f6a25291b39a03d418acc9a3b7136900.jpg

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. 

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.

  • Solution

Thank you.  Run was goodl  however there is just a bit more to cleanup.  There are some leftover exclusions in Microsoft Defender that need cleanup.

This next script will take care to do that.   This should not take but something like maybe 10 or so minutes   ( or less).

First, please Delete the old file Fixlist.txt  that is on Downloads.

 

Please save the (attached file named) FIXLIST.zip   to the   DOWNLOADS folder

 

Fixlist.zip 

This is a ZIP file.   Please Extract the content ( Fixlist.txt)  to Downloads folder.

 

The custom script on this post is ONLY for this machine and NO other.   

  • 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.

 

The system will be rebooted after the script has run.

 

 

  • Start the Windows Explorer and then, to the   Downloads folder.
  • RIGHT click on  FRSTENGLISH.exe   and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow 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:

I uploaded the file I think got me infected to virustotal again, because i did upload it before installing anything the first time, but i did not check the community comments, now I did and I read some guy giving a description of the malware he thinks this file installs so i´m going to give you the virustotal url in case you want to check

https://www.virustotal.com/gui/file/65f264f4f23a619f1a5c4ce3043fa83f7b57d89f2dedcc6ccc8d4c2c18049812/detection

I think my system may still be compromissed because the guy said in the post that they tried to throw you off by messing with your virustotal uploads, and it does feel weird because sometimes i can see the community messages and sometimes i can´t

This system does not now have a infection.  If you want, I can guide you to a couple more of scans. 

Scans have been done with Malwarebytes for Windows + MS Safety Scanner + ESET Online scanner + Microsoft Defender.

Further to that, the 1st custom script rebuilt the Winsock so any theoretical hijack or redirect of internet traffic is nullified.

.

I would recommend getting a readout report as to 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

Thank you.  Just one utility needs to be updated.   Winrar

WinRAR 6.00 (64-bit) v.6.00.0  Download Update    https://www.rarlab.com/download.htm  

.

The Microsoft Defender antivirus is in a good state.  The Trial Malwarebytes for Windows is running & protecting your machine.  Though remember that the trial period ends after 14 days from instal date.

I would suggest you get the Malwarebytes Premium license to have your machine always protected.  The Premium has multiple real-time protections.

.

Let me suggest that you get your browsers each, as applicable, to have the Malwarebytes Browser Guard.

See Support article how-to

https://support.malwarebytes.com/hc/en-us/articles/360038520374-Install-Malwarebytes-Browser-Guard

Note: If your pc has Windows 10 EDGE browser, or Opera or Brave or Vivaldi browser, you can install the Chrome version of the Malwarebytes Browser Guard ( on each as appropriate).

.

I am glad to have worked with you & to have helped you.

To remove the FRST  tool & its work files, do this.  Go to your Desktop folder.  Do a RIGHT-click on FRSTENGLISH.exe & select RENAME & then change it to 

  Quote

UNINSTALL.exe

 .
Then run that ( double click on it)  to begin the cleanup process.

Delete FRST64.exe on the Downloads folder

Delete msert.exe

Delete mb-support-1.8.4.896.exe   on Desktop

Delete securitycheck.exe

Any other download file I had you download, you may delete.

[ BEST PRACTICES ]

Backup is your best friend. Keep backups of your system on a regular basis to offline storage & keep those safe. https://forums.malwarebytes.com/topic/136226-backup-software/

 

 

It is not enough to just have a security program installed. Each pc user needs to practice daily safe computer and internet use.

 

Best practices & malware prevention:

  • Follow best practices when browsing the Internet, especially on opening links coming from untrusted sources.
  • First rule of internet safety: slow down & think before you "click".
  • Never click links without first hovering your mouse over the link and seeing if it is going to an odd address ( one that does not fit or is odd looking or has typos).
  •  
  • Free games & free programs are like "candy". We do not accept them from "strangers".
  •  
  • Never open attachments that come with unexpected ( out of the blue ) email no matter how enticing.
  • Never open attachments from the email itself. Do not double click in the email. Always Save first and then scan with antivirus program.
  • Pay close attention when installing 3rd-party programs. It is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed.
  • Take great care in every stage of the process and every offer screen, and make sure you know what it is you're agreeing to before you click "Next".
  •  
  • Use a Standard user account rather than an administrator-rights account when "surfing" the web.
  • See more info on Corrine's SecurityGarden Blog http://securitygarden.blogspot.com/p/blog-page_7.html
  • Don't remove your current login. Just use the new Standard-user-level one for everyday use while on the internet.
  •  
  • Do a Windows Update.
  •  
  • Make certain that Automatic Updates is enabled.
  • https://support.microsoft.com/en-us/help/12373/windows-update-faq
  •  
  • Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.
