What Is FastBrowser.co?
Reports have emerged about a suspicious website, called FastBrowser.co. The website provides a search engine, with results seemingly provided by the legitimate Yahoo service. However, once a search is initiated, the user is redirected to Microsoft’s Bing search engine. This behavior is suspicious, and none of the services provided by FastBrowser are safe to use. Hence, FastBrowser.co can be categorized as a browser hijacker that causes redirects and pushes sponsored search results. The appearance of intrusive advertisements in the browser is also highly possible.
Furthermore, the developer of the suspicious engine is a company known for other, similar applications. Called AirFind, the company has developed plenty of browser hijackers, including the well-known MobiSearch which has been around for a few years, the m.smartsrch.com redirect, and the Califiesrease.info redirect. All these are known to redirect users to unwanted pages, flood them with ads and scams, and threaten their regular browsing.

FastBrowser.co – More Details
Due to its unexpected appearance and overall behavior, FastBrowser.co is classified as a browser hijacker and suspicious search engine, set to change the settings of your default browser without your knowledge or initial consent. Please note that FastBrowser.co may collect information about your browsing and could share it with third-party advertisers. This is done for monetization purposes.
As a result of having the FastBrowser.co set as your default search engine, it is possible that you start experiencing intrusive pop-up ads, which are often entirely unrelated to your browsing. These ads could contain information about other questionable applications such as system optimizers, virus alerts and detected system issues, or push notifications. Keep in mind that your searches could also be redirected to unwanted and suspicious pages.
Information that FastBrowser.co’s developers may collect about your browsing includes the following:
- Visited URLs and websites;
- Browser’s home page;
- Search queries;
- Search queries on the visited web pages;
- Type of used browser;
- Operating system type;
- Internet protocol (IP) address;
- Geographic location;
- The domain name of current Internet service provider (ISP);
- Diagnostic information which describes how their Services are operating on the system.
NOTE. To avoid the installation of unwanted programs, you should play close attention during the installation of freeware apps. Freeware you recently downloaded from software download pages could have been bundled with FastBrowser.co. Third-party developers may support shady practices for monetization purposes, and may offer you to change your homepage or search provider. You can decline any of these additional offers only if you are careful enough to spot them during installation. In other words, paying attention to the installation setups of freeware could spare you from having to deal with this browser hijacker.
To eliminate any associated risks, we recommend that you remove thoroughly the extension from your browsers and operating system. The next paragraph provides instructions on how to complete the removal process.
