What is Laflurla?

The Malwarebytes research team has determined that Laflurla is a browser hijacker. These so-called "hijackers" alter your startpage or searchscopes so that the effected browser visits their site or one of their choice. This one also displays advertisements.

How do I know if my computer is effected by Laflurla?

You may see these toolbars/add-ons:

How did Laflurla get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was bundled with other software.

How do I remove Laflurla?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program. You will need Malwarebytes Anti-Malware version 2.00 (beta) or newer to disable the Chrome and Firefox extensions.
  • Please download Malwarebytes Anti-Malware to your desktop.
  • Double-click mbam-setup-consumer.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:

    • Enable free trial of Malwarebytes Anti-Malware Premium
    • Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • If an update is found, you will be prompted to download and install the latest version.
  • Once the program has loaded, select Scan now.
  • When the scan is complete , make sure that everything is set to "Quarantine", and click Apply Actions.
  • Reboot your computer if prompted.


Is there anything else I need to do to get rid of Laflurla?

  • The Firefox extension can now safely be removed. Open the "Extensions" tab under "Add-ons" and click "Remove" and "Restart" to complete the removal.

How would the full version of Malwarebytes Anti-Malware help protect me?

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

As you can see below the full version of Malwarebytes Anti-Malware would have protected you against the Laflurla hijacker. It would have warned you before the browser helper object could install itself, giving you a chance to stop it before it became too late.
