Nt.tidesearch.net is a browser hijacker that you might have installed onto your Chrome browser without even realizing it. Although this search tool is unlikely to slither in without your permission, it comes as a by-product of a browser extension called “Tide Search.” According to our researchers, the creator of this suspicious program is unknown; however, it was found that it was built using the SuperWeb engine. Due to this, it is placed in the same category as Sale Planet, Constant Fun, Astro Find, and other infamous advertising-supported programs. A distinctive feature of all of these programs is that they do not last very long. As soon as they serve the purpose, which is to provide third-party advertisers with an advertising platform, they are replaced by new ones. However, it is not common to see browser hijackers attached to them, which is why it even more important to delete this adware. This article discusses the removal of Nt.tidesearch.net, but you will also learn how to eliminate the unwanted extension.

If you have not acquired the hijacker by downloading the extension from tidesearch.com or the Chrome web store, you might have acquired it from a software bundle. At the moment, the Chrome web store list 42 active users, and the app does not have any reviews, which is why it is unlikely that many users have acquired it this way. It is likely that many users are discouraged from installing this program officially because of the permissions notification that appears. The permissions associated with this adware include spying on you, determining your location, communicating with third-party sites, and, of course, modifying your search settings. You are informed that your homepage and your default search provider will be replaced with Nt.tidesearch.net. Despite this notification, some users let this hijacker in without knowing it because they do not pay attention to the information that is associated with the extension. Of course, if the hijacker was installed onto your computer by a third-party downloader, it is possible that it was slipped in without your knowledge, which should help you realize how unreliable it is.

Some users think that Nt.tidesearch.net is a harmless search provider. The interface of this hijacker is very clean, and all you can see is the date on the bottom right corner and the current temperature on the left. You also have the settings menu that allows you to remove these tools and apply the desired background image. However, what is most important is that this search tool does not present information regarding its activity. If you cannot check the privacy policies associated with this tool, you simply cannot trust it! The Privacy Policy at tidesearch.net/privacy/ informs that third-party content could be shown via search results, and you might be exposed to promotions, offers, and other kinds of suspicious content. Regardless of the fact that Nt.tidesearch.net redirects to search.yahoo.com, you could be shown misleading results, which makes this search tool highly unreliable. Unfortunately, many users do not even consider the risks associated with unpredictable content, which is why they get burned without even realizing it. Overall, if you do not want to encounter unreliable content, you should stop using this strange search provider.

You cannot uninstall Tide Search from your computer, and eliminating this extension from the Chrome browser only offers a temporary solution. If you erase the extension, it will be restored the next time you launch your Chrome browser, and that is considered malicious. We have designed a removal guide that will help you erase the unwanted extension and restore your preferred search tools. Hopefully, this is all you will need to do to clean your browsers and your PC. Unfortunately, it is more likely that you will also need to erase other active threats. First, scan your computer to identify these threats. Then, find appropriate removal guides on this site, or, better yet, implement an anti-malware tool to have them eliminated automatically. Another reason to implement this tool is to ensure full-time Windows protection, and that is extremely important if you want to keep your operating system clean in the future.
