How did progreth get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was a forced Chrome extension.
But it was also available in the webstore at the time of writing.

How do I remove progreth?

Our program Malwarebytes can detect and remove this potentially unwanted program.
  • 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 progreth?
  • No, Malwarebytes removes progreth completely.
  • You may have to remove the Chrome Extension manually under Tools > More Tools > Extensions. Click on the bin behind the progreth entry and confirm Remove in the prompt.
