Beware of the Motorsports Start Rogue Extension

Motorsports Start is the name of a rogue browser extension that acts like a browser hijacker.

Browser hijackers are a category of apps that exist between legitimate software and full-on malware. They usually perform undesirable and unsolicited changes to browser settings.

In the case of Motorsports Start, the rogue extension will promote the search dot nstart dot online fake search engine. The engine will replace your browser's default one and will also take the place of your homepage and blank new browser tab content.

Those changes take place without sufficient disclosure and without asking for the user's consent, which is also why this sort of behavior is considered undesirable and browser hijackers are classified as potentially unwanted programs or PUPs.

If you find Motorsports Start in the list of extensions installed in your browser, it's advisable that you remove it and restore your browser's settings to their old values and parameters.
