What is OSDSoft?

The Malwarebytes research team has determined that OSDSoft is a crypto currency miner. These miners are designed to earn cryptocurrency by using system resources.
This particular one is a so-called XMRig (Monero) miner.

How do I know if my computer is affected by OSDSoft?

You may see a file called explorer.exe with this icon:

How did OSDSoft get on my computer?

Miners use different methods for distributing themselves. This particular one was installed by a bundler.

How do I remove OSDSoft?

Our program Malwarebytes can detect and remove this miner.

  • Please download Malwarebytes to your desktop.
  • Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  • Then click Finish.
  • Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  • If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.

Is there anything else I need to do to get rid of OSDSoft?

  • After the reboot you can remove the OSDSoft entry from your list of installed Programs and Features if it belonged to the Trojan.

How would the full version of Malwarebytes help protect me?

We hope our application and this guide have helped you eradicate this trojan.

As you can see below the full version of Malwarebytes would have protected you against the OSDSoft trojan. It would have warned you before the trojan could install itself, giving you a chance to stop it before it became too late.
