Ninja Browser is a Potentially Unwanted Application (PUA) that targets your computer. This app can track your data and act like adware, showing unwanted ads or causing redirects. It might also change your browser settings, like your homepage or search engine, to promote fake search engines. Some PUAs can use your computer’s power for crypto mining or download more unwanted stuff onto your device.
Ninja Browser claims to be an all-in-one tool for browsing, downloading, and keeping your activities private. It promises no ads and safe browsing. But, we found it forces users to use potterfun.com as a search engine. If you search using the address bar, it redirects you through different sites to land on potterfun.com. Potterfun.com isn’t reliable; it may show misleading results and ads, exposing users to scams, phishing sites, and other threats.
Ninja Browser might also gather info such as your location, browsing history, device details, login data, visited websites, and financial info, potentially risking your privacy.
The websites linked with Ninja Browser aren’t trustworthy, and the app itself poses risks. Avoid using it and think about removing it if it’s already on your device for your security and privacy.💡 If you think you have Ninja Browser, follow the steps below to remove it and protect your computer as soon as possible.
