xmrig.moneroocean.stream miner attaches itself to cmd.exe

The title says it all. I tried finding a solution but all of them were system specific.  I have attached the logs and stuff with this post. Someone please help me remove this.

Hello @lwlonewolf and

 

Let's go ahead and run a couple of scans and get some updated logs from your system. Please read the entire post below before starting so that you're more familiar with the process

Then follow each step in the order provided. Unless otherwise asked, please attach all logs

 

Please make the following system changes:

• If you have not done so already - Enable System Protection and create a NEW System Restore Point
• Temporarily disable your antivirus real-time protection or other security software first only if it blocks or interferes with the scans or downloads.. Make sure to turn it back on once the scans are completed
• Temporarily disable Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the downloads are completed
• Disable-Fast-Startup
• Show-Hidden-Folders-Files-Extensions

Please run the following scans:

1. Click the following link and run a  Scan with AdwCleaner
2. Click the following link and run a  Scan with Malwarebytes 
      RESTART the computer
3. Click the following link and run a  Scan with Farbar Recovery Scan Tool

Here are the files, the scan from MalwareBytes was clean. No malware was found. Even though the cmd prompt is still running and eating my resources.

I'm sorry I don't understand. Am I supposed to do something here?

No, that was a user breaking the forum rules. They are not supposed to post to other user topics. I have deleted their post.

Where is the scan log for Malwarebytes?

 

Please run the following

 

 

Dr.Web CureIt!

Please download the Dr.Web CureIt! anti-virus utility
https://free.drweb.com/

 

You will need to send them an email to obtain a link to download the scanner, please do so

• The downloaded file will normally have a unique name such as:  q7a9tr4p.exe
• Close all open applications and locate the downloaded file and double-click to run it
• The program will take a moment to launch and bring up the License and Update screen
• Place a check mark to agree to the terms and then click on the Continue button
• Click the underlined link Select objects for scanning
• On the top left click the Scanning objects that should automatically check all objects
• Click the small wrench and make sure there is a check on Automatically apply actions to threats
• Then click the large button on bottom right Start scanning
• Once the scan has completed there will be a link named Open report click that and a log named cureit.log should open in Notepad
• The log is saved in the folder named Doctor Web in the top of your user profile folders
• Please attach that log on your next reply

I wasn't available earlier on. Here are the logs. I hadn't run malwarebytes previously. Ran it again just now, only thing that turned up was a sketchy thing I downloaded which isn't related to the current problem :)

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

The Scan currently took 12hours. Reached 99% (the bar was completely filled) and my windows crashed... sigh... there's no log for it now. Do i have to run it again from the start 

[lwlonewolf]

For the record, the last time i saw the tool screen it had 65 detections.

At this point since scanners cannot even complete scans I would recommend you back up your data and then reinstall Windows clean.
