System Infected: Miner.BitcoinMiner Activity 7 and 9

[Martin_K]

Hello,

First of all sorry for my bad english in some cases. I am adressing to you, because in few days ago my antivirus program (Norton) started to catch some suspicious activity and showing me warning messages every 20-40min "System Infected: Miner.Bitcoinminer Activity 7" and "System Infected: Miner.Bitcoinminer Activity 9" (I am not getting any redirecting, random web pop ups, etc,.. only message that IP was blocked trying to attack my PC). I've already made a topic on Norton forum, but they recommended me you aswell. (What I have already tried you can in this link).  I also observed that warning messages show 2 IP adresses, which is always same. I tried to block blacklist them in my modem Firewall settings (see screen.PNG), but warnings keep showing. I have also tried procedures made in this post, but I was unfortunate. In attachement you can find Addition.txt + FRST.txt from FRST64.exe program and Recent History.txt exported log from Norton program, screen of mentioned Firewall blacklisted IP)

My CPU, GPU, SSD (system) and SSHD has 0% usage in idle mode, temperatures are okay. Even when components are on load, system is stable and okay.

What I tried to solve it in shortcut: removed cache, cookies, check PC with both Norton and Malwarebytes (all was clear)

My modem: Asus DSL-AC52U

Using web browser - Mozilla Firefox

OS: WIN10 Home

 

Thank you for your replies and your time!

 

Kind regards
Martin

Hello @Martin_K and

Let me have you run the scans in the following order and we'll see what we can find.

 

Please run the following steps and post back the logs as an attachment when ready.

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 Now.
• When finished, please click Clean & Repair.
• 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.

 

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

 

Thanks

Ron
