What is NCH Toolbar?

The Malwarebytes research team has determined that NCH Toolbar 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.

How do I know if my computer is affected by NCH Toolbar?

You may see this these browser extension in Chrome:

How did NCH Toolbar get on my computer?

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

How do I remove NCH Toolbar?

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 NCH Toolbar?
  • 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 NCH Toolbar entry.
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.
