What is Neurowise?
The Malwarebytes research team has determined that Neurowise 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 Neurowise?
This is how the first screen of the installer looks:

And you may see these toolbars/add-ons:

How did Neurowise get on my computer?
Browser hijackers use different methods for distributing themselves. This particular one was bundled with other software.
How do I remove Neurowise?
Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted application.
- 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.
- No, but for a full removal of the Firefox add-on you will need Malwarebytes Anti-Malware 2.00 beta or newer.
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 Neurowise 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.
