Hello @haeusermannanna and welcome back:

While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

1. Download the Malwarebytes Support Tool.
2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
4. Run the MBST Support Tool.
5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have sent.

Thank you.

I will do a requested and follow strictly the orders the Malwarebyte Expert will provide me with. Thank you. Below you find the attached MBST Grab results zip. While I follow strict orders my cat Bagheera did not and restarted the infected PC. I ran the Support Tool anyway.

Hello @haeusermannanna:

Unfortunately, the resulting .zip file was incomplete. Please repeat and make certain a good Internet connection sustains throughout the gathering process. Then, post the new result.

Thank you.

[haeusermannanna]

I am so very sorry. I ran it again and this time it stayed longer on the FRST. I attached the new Zip below. I hope it is now complete. mbst-grab-results.zip

I don't see an obvious infection.

Please try to start into Safe Mode and if that works then try running the following if it will let you.

 

 

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well
 

STEP 1

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

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

• Once you see it has started, take a long long break;  walk away.  Do not pay credence if you see some intermediate early flash messages on the screen display.  The only things that count are the End result at the end of the run.
• The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

It is normal for the Microsoft Safety Scanner to show detections during the scan process.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

Then it writes into the log on your computer what it found.

 

Thank you

 

[haeusermannanna]

Thank you very much. I will do that during the night. I can sleep and the PC can work :)) Once it is finished I will upload the Result of the scan here.

Hello

I ran the Microsoft Safety Scanner. Although I am an Idiot and forgot to run it in SAFE Mode. I ran it in Windows 11. Attached you find the info I have gotten after it finished. The link I received is in the MSG.log file I had to change the Name of the File so I could save the log. There is only 1 Malware it found. Thank you so much for your support and help I highly appreciate it.

That's okay to run in Normal Mode. I thought you said it had no Internet access in when trying to start in Normal Mode

Let's try another scanner @haeusermannanna

• When prompted for scan type, Click on the Full Scan button
• Enable  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click the Start scan button.
• Have patience.  The entire process may take a few hours or more.
• 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 and give it a name and location you remember.

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

 

STEP 01

• If you already have Malwarebytes 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 yet please download it from here and install it.
• Once installed then open Malwarebytes and select Scan and let it run.
• 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 or other location you can find and attach that log on your next reply.
• 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 attach 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 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Double-click to run the program
• Accept the End User License Agreement.
• Wait until the database is updated.
• Click Scan Now.
• When finished, if items are found please click Quarantine.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
• Please attach the Additions.txt log to your reply as well.
• On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.
