What is YoutubeAdBluockee?

The Malwarebytes research team has determined that YoutubeAdBluockee 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 affected by YoutubeAdBluockee?

How did YoutubeAdBluockee get on my computer?

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

How do I remove YoutubeAdBluockee?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.

• Please download Malwarebytes Anti-Malware to your desktop.
• Double-click mbam-setup-version.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. Or select the Threat Scan from the Scan menu.
• 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 YoutubeAdBluockee?

• These Multiplug variants delete the Browser Helper Objects key for Internet Explorer from the Windows registry. This will cause possible errors and instable behaviour of this browser. You may have to re-install some software to cure this.

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 YoutubeAdBluockee hijacker. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
