What is Bit Driver Updater?

The Malwarebytes research team has determined that Bit Driver Updater is a "driver updater". These so-called "system optimizers" use intentional false positives to convince users that their systems have problems. Then they try to sell you their software, claiming it will remove these problems.
More information can be found on our Malwarebytes Labs blog.

How do I know if I am infected with Bit Driver Updater?

This is how the main screen of the system optimizer looks:

You will find these icons in your taskbar, your startmenu, and on your desktop:

and see this type of warning during install:

and this type of screens during "operations":

You may see this entry in your list of installed programs:

and these tasks in your list of Scheduled Tasks:

How did Bit Driver Updater get on my computer?

These so-called system optimizers use different methods of getting installed. This particular one was downloaded from their website:

How do I remove Bit Driver Updater?

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

  • Please download Malwarebytes for Windows to your desktop.
  • 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 Bit Driver Updater?

  • No, Malwarebytes removes Bit Driver Updater completely.
  • This PUP creates some scheduled tasks. You can read here how to check for and, if necessary, remove Scheduled Tasks.

How would the full version of Malwarebytes help protect me?

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

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