Remove Proto-search.com
Proto-search.com is a low-quality search engine, which relies on shady software to attract more users and generate more traffic. Unfortunately, Proto-search.com's creators have no interest in providing their users with reliable services – instead, they want to maximize their ad revenue. Because of this, Proto-search.com may prioritize sponsored results, advertisements, pop-ups, and other marketing content that is irrelevant to most users.
Needless to say, no one in their right mind would opt to visit Proto-search.com on purpose – and the website's creators know this. This is why they use the aforementioned shady apps to bring more users. Typically, these apps are considered to be browser hijackers or Potentially Unwanted Programs (PUPs,) and their sole goal is to manipulate browser settings. For example, you might end up at Proto-search.com when you load a new tab, or if you try to initialize a new Web search through the address bar.
Trying to get rid of the Proto-search.com redirect manually may result in failure, because the browser hijacker/PUP responsible for these changes will reapply its settings immediately. To solve the issue completely, you must eliminate the root of the problem – the intrusive app working in the background. You can do this by using a suitable Windows or Mac security tool, which will help remove the Proto-search.com hijacker completely.
