Removal instructions for PC Reg Boost

1 post in this topic

ID: 1   Posted

What is PC Reg Boost?

The Malwarebytes research team has determined that PC Reg Boost is a "system optimizer". 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 PC Reg Boost?

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

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

and see these warnings during install:

and these screens during "operations":

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

How did PC Reg Boost get on my computer?

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

How do I remove PC Reg Boost?

Our program Malwarebytes can detect and remove this potentially unwanted application.
  • 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 PC Reg Boost?
  • No, Malwarebytes removes PC Reg Boost completely.
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 PC Reg Boost installer. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
