Removal instructions for BestBackground

Recommended Posts

What is BestBackground?

The Malwarebytes research team has determined that BestBackground is a browser hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice. This one also displays advertisements.

BestBackground is a Mindspark/Ask toolbar now known as IAC Applications.

How do I know if my computer is affected by BestBackground?

You may see these browser extensions/add-ons:

How did BestBackground get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from their site.

How do I remove BestBackground?

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

You can use their own uninstall instructions first, but I would advise to follow the steps below anyway.

  • 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 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 BestBackground?
  • If you are using Chrome, you may have to remove the Extension manually under Tools > Settings > Extensions. Remove the checkmark and click on the bin behind the BestBackground entry.
  • If you are using Chrome or Firefox, you should be redirected to our Restore Browser page. You can read there how to fix additional browser redirect methods.
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 BestBackground hijacker. It would have warned you before the hijacker could install itself, giving you a chance to stop it before it became too late.
