And this type of software has earned its name because it literally hijacks your browser by taking control over certain browser settings. For instance, it can add new toolbars and plug-ins to your favorite browsing program. And in addition to that, you can expect it to change your default search engine and even the browser’s homepage.

Flexible Sector and its cousins like Accessible Search Engine are capable of integrating with the most popular browsers such as Chrome, Firefox and Safari. In addition, hijackers like this have a reputation for installing ad-generating components as well. This results in you seeing large quantities of online ads in various shapes and sizes: from popups and banners to box messages and in-text links. In addition, you may experience frequent page redirects as a result of Flexible Sector’s activity.

What is Flexible Sector?

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.
