Before I did the Farbar Recovery Scan, I had run Advanced SystemCare and scanned if there was anything wrong and automatically fixed it. Therefore, i viewed the scanning results, figured it out that some errors of missing files had been fixed and restart the computer. Since then, I tried to reinstall Malwarebytes. But still, it didn't work so I downloaded and ran Farbar Recovery Scan Tool and here are the results.

What is this file about?

Was this computer infected by some type of ransomware attack before?

C:\Program Files\XAHGQBAXZ-DECRYPT.txt
C:\Users\admin\AppData\Roaming\XAHGQBAXZ-DECRYPT.txt

 

This is a PowerShell script and the location is not normal. What is this for?

C:\Users\admin\AppData\Local\script.ps1

 

This is a hidden folder. Why? What is in this folder?

C:\Users\admin\AppData\Roaming\ecf00c38dc807e105d881c433a6b455dd2c606b6

 

 

Please go into Control Panel, Programs, Programs and Features and uninstall the following software

Bonjour

 

 

System errors:
=============
Error: (07/01/2021 05:35:24 PM) (Source: Microsoft-Windows-DNS-Client) (EventID: 1012) (User: NT AUTHORITY)
Description: There was an error while attempting to read the local hosts file.

 

Please run the following fix

 

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Note: If the tool warned you about an outdated version please download and run the updated version.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

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.

fixlist.txt

Thanks

C:\Users\admin\AppData\Roaming\XAHGQBAXZ-DECRYPT.txt

  • Yes, I thought the same thing, too. A couple of weeks ago I found out that my computer, which belonged to one of my relatives, has many files with the same XAHGQBAXZ-end and text doc about recovering data. All the files were created in Jan, 2019.

C:\Users\admin\AppData\Local\script.ps1

  • It was created in 2019, when this computer hadn't been given to me, so I don't know the reason.

  • I can't remember why it was created yesterday. Could I upload the file to give it a look?

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.

  • Thank you for the instructions, here's the log.

Yes, a bad file. It's written to disable your antivirus. Please delete it.

Set-MpPreference -DisableRealtimeMonitoring $true

 

 

 

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

Ultimately you'd want all your scans to come back clean.

I'd also recommend you do some research about iObit and make up your own mind if you really want that software on your system or not.

If you want further assistance on clean up let me know

Take care and stay safe out there

Cheers
