After turning on my computer, random Chrome browsers appears

Hello, I think I have a similar problem as someone from the post: https://forums.malwarebytes.com/forum/7-windows-malware-removal-help-support/?do=add

In my case, after turning on the computer, the antivirus always signals that the computer is protected against the dangerous CL.Suspexec!gen159 action.

Some time later, while using the computer, the cmd console appeared out of nowhere. Since then, every time I start it, a lot of Chrome browsers are accidentally launched and running in the background. After deleting activities from the task manager, a notification appears that the "violetmonkey" addon has stopped working. I also have the same problem on my computer with the zsync_desktop file and System32/WDNA running which causes CL.Suspexec!gen159 to appear.
 

I don't have a photo of the browsers because I deleted them, but they look the same as in the linked post: https://forums.malwarebytes.com/forum/7-windows-malware-removal-help-support/?do=add

Hello  @daaaad  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 attach 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.

 

 

I would like you to give MBAM and ADW a chance. Run both tools, delete every detected element and attach both logfiles.

Thank you.

@daaaad

We will use Farbar Recovery Scan Tool (FRST) to run a fix. FRST was downloaded together with MBST and should be located in your download folder: C:\Users\Komputer\Downloads\FRSTEnglish.exe

The fix may take some time (>> 10 min), please be very patient and do not interfere.

 

 

  • Please download the attached fixlist.txt file and save it to your download folder, which is C:\users\Komputer\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.
  • 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, empty recycle bin and will remove cookies and may result in some websites indicating they do not recognize your computer. It may be necessary to receive and apply a verification code.
  • Please note: This step resets your Firewall settings and you may be asked later to grant permission for legitimate programs to pass through the Firewall. If you recognize the program, agree to the request.
  • 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 20.02.2023_11.33.52.zip, on your desktop as well. Please attach this file as well with your next answer.

Thank you!

You can delete this zip file from your desktop now!

 

Were we able to solve your problem regarding these fake chrome browsers?

 

I suggest to run ESET and SecurityCheck for a second opinion.

 

 

1️⃣

 

Let me have you run a different scanner to double-check.

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

 

 

 

2️⃣

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

is this a rhetorical question?

eset.txt

I did everything to use the eset program, but I can't open the securitycheck program, it shows that it is not adapted to my system or something

and I can't delete this file because I don't have permissions

No, it isn't. When it comes to malware, we speak plainly... no irony, no rhetorical questions.

 

I want to know if you still notice these problems or if our fix was successful? 🙂

Thank you for clarifying.

 

After restarting the computer, Google Chrome windows no longer appear, the antivirus does not find the CL.Suspexec!gen159 threat and there is no sign of zsync_desktop.exe in task manager so i think im good for now. 

 

Big thank you for your patience and help.

Thanks for your detailed feedback. 😃

You're welcome!

 

 

Thank you for your cooperation. You can use KpRm to remove FRST and other tools.

 

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 can be found here:
