How do I remove Download Converter Free?

Our program Malwarebytes can detect and remove this potentially unwanted program.

  • Double-click MBSetup.exe and follow the prompts to install the program.
  • When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
  • Click on the Get started button.
  • Click Scan to start a Threat Scan.
  • When the scan is finished click Quarantine to remove the found threats.
  • Reboot the system if prompted to complete the removal process.

Is there anything else I need to do to get rid of Download Converter Free?

  • No, Malwarebytes' Anti-Malware removes Download Converter Free completely.
  • If your browsers have been hijacked, you should read our Restore Browser page. You can read there how to fix additional browser redirect methods.

How would the full version of Malwarebytes help protect me?

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

As you can see below the full version of Malwarebytes, as well as Browser Guard, would have protected you against the Download Converter Free hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
