What is Rostpay?

The Malwarebytes research team has determined that Rostpay is a bundler. These bundlers typically install potentially unwanted programs (PUPs) or adware on top of the desired software.

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

You may see these warnings during install:




The additional offers can vary with the product you're installing and your location. In this example we used DriverHub on a system in the UK.

How did Rostpay get on my computer?

Bundlers use different methods for distributing themselves. This particular one was downloaded from their website:



How do I remove Rostpay?

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 Rostpay?

• No, Malwarebytes removes Rostpay completely.
• If you wish to remove the installed programs and extensions you can use the normal procedure from the Windows Control Panel for the programs and the browser extensions from the browser.

How would the full version of Malwarebytes help protect me?

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

As you can see below the full version of Malwarebytes would have protected you against the Rostpay bundler. It would have blocked the installer before it became too late.
