However, this is mis-used by malware makers who infect hundreds of PCs in order to run various BitCoinMiners. They gain money much more effectively compared to legitimate ones as they do not have to pay for electricity or computers that perform the calculations. The longer malware mines on infected PCs, the more Bitcoins cyber-criminals get for free.

  1. Great post! I did a recent article on how to remove BitcoinMiner malware and the assessment was well worth it. My evaluation of the malware was quite intriguing and I showed how the malware operates and uses a computer’s resource without the knowledge of the user. Online users should definitely beware of this malware or else the creators of BitCoinminer will have their computer working as a slave.

  2. Great article, this second time I got this type of infection on my gaming rig an hit man pro works wonderful. I’m positive both times my infection came from a mod site for games as this is only time my PC is online ever. I have a laptop for regular internet activities, this being said be careful what you download.

  3. If you’re here because of a miner from a recent TORRENT this is what you should do:
    This particular miner is disguised as an issch.exe process;
    -Open task manager and look for “issch.exe”-> “Open file location”
    -Delete the whole folder that’s holding the exe file
    -End “issch.exe” process tree from task manager
    -Open “Task Scheduler”->look in “Active Tasks” tab for one with location= “\”
    -look in every tasks’ “Actions” tab to find the one that runs the process at the folder location you deleted, and delete that task

    Hope this helps.

  4. I have a wanring coming up on mu computer that “Miner has stopped working”. Should I be concerned about this?

  5. Hello, Terry, thank you for your question. To be able to answer it, I need to know whether you do use Bitcoin Miner to mine bitcoins on purpose, or you have never done it and this message just showed up on your computer?
