Deleted RiskWare.BitCoinMiner comes back after every restart

Recommended Posts

Hello, 

some days ago I noticed some performance issues on my PC.

Somehow I got a miner using my GPU in the background. Eventually I bought Malware Bytes Premium to get rid of it permanently.
Unfortunately after every restart I get a threat detection even though I deleted them after sending them to quarantine.

After trying it alone for some evenings I'm seeking some help here.

Please let me know if I need to provide further information.

Best regards!

Hi,

Thanks for posting in the Malware Removal for Windows Help forum. Being infected is not fun and can be very frustrating to resolve, but don't worry because we have a team of experts here help you!!

Note: Please be patient. When the site is busy it can take up to 48 hours before a malware removal helper can assist you. If no one has replied to your new topic after 48 hours please contact a Moderator or Administrator to let them know.

 

First, if you haven't done so, please run a Threat Scan with the latest version of Malwarebytes. This may resolve your malware infection issue without the need for additional support. Click "Reveal Hidden Contents" below for details:

Malwarebytes can detect and remove most malware with no further actions required for free.

If you do not have Malwarebytes, please download it here and install. Be sure to post back the log as shown below.

  1. Open Malwarebytes for Windows
  2. To the left, click Scan > Scan Types.

  3. Select Threat Scan. Threat Scan is the most thorough and recommended scan method available.

  4. Click Start Scan

Next, if you're still experiencing issues after running Malwarebytes, then technical logs will be required to assist you. Click "Reveal Hidden Contents" below and follow the instructions to run the Farbar Recovery Scan Tool:

Spoiler

Don't use any temporary file cleaners unless requested - this can cause data loss and make a recovery difficult.

Please download the Farbar Recovery Scan Tool here 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

  1. Double-click to run it. When the tool opens click Yes to the disclaimer.
  2. Press the Scan button.

  3. It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  4. The first time the tool is run, it also makes another log (Addition.txt). If you've run it before it may not and you may need to select it manually.

Finally, attach the Malwarebytes Threat Scan, FRST.txt and Additional.txt logs to your reply. Before submitting your reply, be sure to enable "Notify me of replies" like so: notify me.jpeg

Click "Reveal Hidden Contents" below for details on how to add attachments to your post.

Please Note the Following:

  • One of our expert helpers will give you one-on-one assistance when one becomes available.
  • Refrain from making any further changes to your computer (such as Install/Uninstall programs, using special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.
  • Do not 'bump' or add a reply to your topic once it is started. Topics which appear to have replies are considered to have a helper assisting them and may be overlooked, resulting in a longer waiting period for help
  • If you're using Peer 2 Peer software such as uTorrent or similar, please completely disable it from running while being assisted here.

Hi Rjd2 :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.

  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
  • As long as I'm assisting you on Malwarebytes Forums, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against Malwarebytes Forums's rules
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread


This being said, it's time to clean-up some malware, so let's get started, shall we? :)

Please give me some time to review your logs and get back at you.

Hi Aura,

thank you very  much!

Somehow no editor opened after scanning. I copied the logfile from the same directory as FRST.

Good! Now can you do me a favor? Can you .zip the C:\FRST\Quarantine folder and attach it here?

Thank you :) Now if you restart your computer and run a scan with Malwarebytes, is it detecting anything?

Not yet. :) 

But I think it might come back. I ran FRST before I posted here also and still after the restart I got the security warning of malwarebytes.
Maybe the 2nd time running FRST helped. If not I will reply to this thread, okay?

Thank you for your support!
