Bitcoin Miner installed under Livecomm.exe

Recommended Posts

About a week ago a bitcoin miner was installed on my computer.  It's normally dormant, but occasionally I'll see what appears to be a cmd window pop-up for a split second, and then my CPU and GPU rocket up to 100% load.  When this happens I'm able to get rid of it using a Quick Scan, (log attached below) and upon resetting everything appears to be normal.  However it will eventually re-install itself, and the problem continues.  I've done a full scan with MBAW, and the new Anti-rootkit software, and neither of them can find any type of infection before it re-installs itself.

download Farbar Recovery Scan Tool and save it to your desktop.


Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

There are network proxies running in Firefox, are you aware of them? OK we continue:


Download attached fixlist.txt file and save it to the Desktop.


NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.


Run FRST and press the Fix button just once and wait.


The tool will make a log on the Desktop (Fixlog.txt). Please post it to your reply.




Delete any versions of Combofix that you may have on your Desktop, download a fresh copy from the following link :-




  • Ensure that Combofix is saved directly to the Desktop <--- Very important
  • Disable all security programs as they will have a negative effect on Combofix, instructions available here  http://www.bleepingcomputer.com/forums/topic114351.html if required. Be aware the list may not have all programs listed, if you need more help please ask.
  • Close any open browsers and any other programs you might have running
  • Double click the combofix.gif icon to run the tool (Vista or Windows 7 users right click and select "Run as Administrator)
  • Instructions for running Combofix available here http://www.bleepingcomputer.com/combofix/how-to-use-combofix if required.
  • If you are using windows XP It might display a pop up saying that "Recovery console is not installed, do you want to install?" Please select yes & let it download the files it needs to do this. Once the recovery console is installed Combofix will then offer to scan for malware. Select continue or yes.
  • When finished, it will produce a report for you. Please post the "C:\ComboFix.txt" for further review


****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****


Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.

Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell us when you reply. Read here  http://thespykiller.co.uk/index.php?page=20 why  disabling autoruns is recommended.



    If Combofix detects any Rootkit/Bootkit activity on your system it will give a warning and prompt for a reboot, you must allow it to do so.
    If Combofix reboot's due to a rootkit, the screen may stay black for several minutes on reboot, this is normal
    If after running Combofix you receive any type of warning message about registry key's being listed for deletion when trying to open certain items, reboot the system and this will fix the issue (Those items will not be deleted)


Post the logs in next reply please...

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Open notepad and copy/paste the text in the Codebox below into it:


Save this as CFScript.txt, and as Type: All Files (*.*) in the same location as ComboFix.exe



Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Your Java javaicon.gif is out of date. Older versions have vulnerabilities that malware can use to infect your system.

Please follow these steps to remove older version of Java components and upgrade the application.


Upgrading Java:


Go to http://java.com/en/ and click on "Do I have Java"

It will check your current version and then offer to update to the latest version

Watch for and make sure you untick the box next to whatever free program they prompt you to install during the installation, unless you want it.


***Note: Check in Programs and Features (or Add/Remove Programs if you are an XP user)  If Java 7 Update 9 is still present, remove it...


Microsoft Security Essentials is listed as disabled, is that correct? Can you turn on realtime protection, does it work ok,


Let me know if you have any remaining issues or concerns...
