Riskware.BitCoinMiner Detected

[DannyZuko]

Hello,

Malwarebytes Premium detected Riskware.BitCoinMiner on my Windows 10.  I instructed Malwarebytes to quarantine the files, then restarted my computer, then deleted the files.  My scan was set to run every 3 days, so I may have had this riskware for up to 3 days.

The Malwarebytes blog made it sound like this riskware poses no real threat, however, other websites said that this riskware records all keystrokes and analyzes or sells it to others. (!)

I just want to know if I need to take any further action now that I deleted the files.  Theoretically, I could change all of my passwords...but if that's not necessary I really would rather not.

Thanks!

Hello @DannyZuko and

Please post the log where you removed any threats.

 

Please run the following steps and post back the logs as an attachment when ready and we'll make sure the computer is clean.

STEP 01

• If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• If you don't have Malwarebytes 3 installed yet please download it from here and install it.
• Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• Once the scan is completed click on the Export Summary 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 on your next reply.

STEP 02

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

• Right-click on the program and select Run as Administrator to start the tool.
• Accept the Terms of use.
• Wait until the database is updated.
• Click Scan.
• When finished, please click Clean.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Copy its content into your next reply.

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.
• Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron

Hi Ron,

Thanks for your help.  Attached are the logs from Malwarebytes Premium and from AdwCleaner.  Windows Defender didn't like the Farbar FRST tool, so I have not used that.

My main question is if I need to change all of my passwords since I read that the Riskware.BitCoinMiner captures keystrokes.  The files were quarentined and then I deleted them with Malwarebytes.

Much appreciated,

DannyZ

You need to allow FRST to download and run please. That will tell us what is really going on. The tool is very safe and used thousands of times a week on the Internet to help people just like you.

Thank you

Ron
