Do you know what Pesquisa.ninja is?
It is highly unlikely that you have replaced your regular homepage on IE, Chrome, and Firefox browsers with Pesquisa.ninja yourself. This means that this search provider was installed without your permission, which makes it a browser hijacker. No matter how attractive or harmless a browser hijacker might look, you must remove it just because it has the power to invade your operating system in an illegal manner. Unfortunately, Pesquisa.ninja is not a harmless hijacker, and there are several other reasons to delete it from your operating system right now. According to our research team, it is most likely that you will need to remove Pesquisa.ninja if you live in Brazil.
As you might have noticed, official information representing Pesquisa.ninja does not exist. This search provider does not showcase its privacy policies, does not disclose its developer, and does not allow the users to learn how it works. It appears that the only function this hijacker has is to assist you when browsing the web; however, trusting Pesquisa.ninja would be a great mistake. This search tool redirects users to third-party search engines, and, even if you are familiar with them, you should not interact with the search results provided. Br.search.yahoo.com is one of the search tools that you might be redirected to. Needless to say, Yahoo is a reliable search provider, but the version introduced to you by Pesquisa.ninja might have been changed/modified to serve the creators of the hijacker. Have you noticed suspicious ads or sponsored links? These could be injected by the hijacker or ad-supported programs that are known to travel bundled with it. As you can guess, adware requires removal as well, but, at this moment, it is most important that you delete Pesquisa.ninja.
