Browser keeps opening magybu.net and gestyy.com


Recommended Posts

My browser (Opera GX) keeps opening these tabs on startup. I have run Malwarebytes numerous times. It detected two 'PUM' files which I put under quarantine and deleted. I then restarted the computer and to my surprise the same two sites opened again. I have had this issue for quite some time and have tried numerous guides and anti-virus scans.

Hello @hippiesad  and  :welcome:

 

My name is MKDB and I will assist you.

 

 

Some ground rules:

  • Please follow the steps in the given order and post back the log files.
  • Please attach all log files into your post.
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
  • Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting and removing malware isn't instantaneous and there is no guarantee to repair every system. Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Please be patient and stick with me until I give you the "all clear".
  • 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.
  • 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 big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
  • As English is not my native language, please do not use slang or idoms. It may be hard for me to understand.
  • If you do not respond within 4 days, your topic will be closed.

 

 

 

Step 1

  • If you already have Malwarebytes Anti-Malware 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 or if you don't run the newest version yet, please download it from here and install it.
  • Once the MBAM dashboard opens, click on Settings (gear icon).
  • Click on Security tab and make sure that all four Scan options are enabled.
  • Close Settings and click on the Scan button on the dashboard.
  • 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.
  • 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 paste 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 2

Please download AdwCleaner and save it to your desktop.

  • Double-click to run it.
  • Accept the End User License Agreement.
  • Click Scan Now.
  • When finished, if items are found please click Next / Quarantine.
  • Maybe your PC will be rebooted, AdwCleaner will be opened automatically.
  • Click View Log File.
  • AdwCleaner will open one log (AdwCleaner[Cxx].txt).
  • Please paste the log to your next reply.

 

 

 

Step 3

Please download the suitable version of Farbar Recovery Scan Tool (FRST) and save it to your desktop: 32bit | 64bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Check the box in front of Shortcut.txt.
  • Press the Scan button.
  • FRST will create three logs (FRST.txt + Addition.txt + Shortcut.txt) in the same directory the tool is run.
  • Please attach these logfiles to your next reply.

Please follow my instructions carefully. You should download and run FRST from your desktop (C:\users\admin\desktop\) and not from a temporary location:

Running from C:\Users\admin\AppData\Local\Temp\scoped_dir14148_1597015898    <--- that's not the correct location

 

 

Is this file from you? If so, what can you tell me about it?

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\update.bat

 

 

 

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.

 

 

Thank you @hippiesad.

Hello, after investigating the update.bat program I have found out that it the exact file which was causing the issue. After i ran it it immediately prompted me up with the two sites in question. Thank you for your help. You can close the listing if you wish.

Hi @hippiesad,

Thank you very much for your feedback.

Is it possible to attach the update.bat with your next answer for me? I would like to have a look on this file if possible. Or have you already deleted it on your own?

 

Your system contains some system modifications that I want to fix with FRST. Moreover, i would like to check your windows system files. If you agree, I would run at least a FRST-Fix and do another check with another scanner.

Let me know if you are interested in it.

Thank you for the upload @hippiesad.

The FRST-Fix may take some minutes (> 10), please be very patient and let FRST do it's job.

 

Step 1

  • Please download the attached fixlist.txt file and save it to the location where you ran FRST from ( C:\Users\admin\OneDrive\Počítač\ ).

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.
  • 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.

Thanks @hippiesad.

That was a good run.

 

 

Step 1

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

Thanks @hippiesad.

I use google translator if necessary. 😉

 

 

Thank you for your cooperation, we're done.

 

Final Step

  • Right-Click on FRST64 and choose Rename.
  • Rename FRST64 into Uninstall.
  • Run Uninstall.
  • FRST and it’s files/folders will be deleted.
  • If the tool needs a restart, please make sure you let the system restarts normally.

 

 

 

 

 

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.
