Hello @rashua  and  :welcome:

 

My name is MKDB and I will assist you.

 

 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow the steps in the given order and post back the log files.
  • Please copy and paste all log files into your post.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Only run the tools I guide you to. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • As English is not my native language, please do not use slang or idioms. It may be hard for me to understand.
  • If you do not respond within 4 days, your topic will be closed.
  • Cracked 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 a big source of current trojan infections. If you are running any kin of illegal software on your system, please uninstall them now, before we start the cleaning procedure.

 

 

Step 1

  • Please download the Malwarebytes Support Tool (MBST).
  • Run MBST and accept license agreement.
  • In the left navigation pane of MBST, click Advanced.
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine.
  • A zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file on your next reply.

First @rashua ... You also forgot to mention that you run illegal/suspicious software:

Quote

Date: 2023-03-21 16:51:47
Trojan:Script/Wacatac.H!ml
 file:_C:\Users\PC\Downloads\Sony_Vegas_Pro.rar

Stop that now!

 

 

Second, please uninstall the following software via Start > Settings > Apps:

Taskbar system version

 

 

 

Third, please run the following FRST fix (Step1) and attach the logfile (fixlog.txt) as well as the .zip file.

 

 

Step 1

  • Please download the attached fixlist.txt file and save it to your download folder, which is C:\users\HP\Downloads\ in your case.
  • You will find the file FRSTEnglish.exe (FRST) as well in this folder.

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

  • Close all open programs and save your work.
  • Run FRST again.
  • Press the Fix button only once and wait. Please be patient and do not interfere, even if FRST does not respond for some time. That's nothing to worry about.
  • Please note: This Fix will remove all temporary files and empty recycle bin.
  • If the tool needs a restart, please make sure you let the system restart normally and let the tool complete its run after restart.
  • FRST will create one log now (Fixlog.txt) in the same directory the tool is run.
  • Please attach this logfile to your next reply.
  • FRST will create a .zip file like < Date_Time.zip >, for example 20.02.2022_11.33.52.zip, on your desktop as well. Please attach this file as well with your next answer.

Well done @rashua.

 

Please run KVRT and SC as well for me to double check your system.

Thank you!

 

 

Step 1

Download Kaspersky Virus Removal Tool (KVRT) and save it to your Desktop.

  • Select the Windows Key and R Key together, the Run box should open.
  • Copy and paste the following string into the line:

C:\Users\PC\Desktop\KVRT.exe -dontencrypt

  • Select „Ok“ in the Run box.
  • If the „Windows protected your PC“ window opens, select „More info“. A new windows will open, select „Run anyway“.
  • An EULA window from KVRT will open, tick all confirmation boxes then select "Accept".
  • A window from KVRT will open, select "Change Parameters".
  • In the new window ensure the following boxes are ticked:
    • System memory
    • Startup objects
    • Boot sectors
    • System drive
  • Then select "OK" and „Start scan“.
  • 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:

C:\KVRT2020_Data\Reports\report_<data>_<time>.klr

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

 

 

Step 2

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • 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 a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

^Please run Acrobat DC and go Help - Check for updates...^

 

 

Thank you for your cooperation @rashua

 

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, select Delete Tools under Actions.
  • Under Delete Quarantines select Delete Now, then click Run.
  • Once complete, click OK.
  • A log may open in Notepad titled kprm-(date).txt.  I do not need it. Just close Notepad if it shows up.

 

 

 

A few final recommendations:

  1. Recommend using a Password Manager for all websites, etc. that require a password. Never use the same password on more than one site.
