What is PBlock+?

The Malwarebytes research team has determined that PBlock+ is a potentially unwanted program that behaves like adware. These adware applications display advertisements not originating from the sites you are browsing.
This particular one claims to be a popup-blocker but redirects to search hijackers.

How do I know if my computer is affected by PBlock+?

You will see this extension in your list of installed Chrome extensions:


You may see these warnings during install:






How did PBlock+ get on my computer?

Adware applications use different methods for distributing themselves. This particular one was available in the Webstore:


after a redirect from an adrotator.

How do I remove PBlock+?

Our program Malwarebytes can detect and remove this adware program.
  • 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 PBlock+?
  • No, Malwarebytes removes PBlock+ completely.
How would the full version of Malwarebytes help protect me?

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

As you can see below the full version of Malwarebytes, as well as Browser Guard would have protected you against the PBlock+ adware. It would have blocked the redirector before it became too late.
