What is File Converter Master?

File Converter Master is a potentially unwanted program that infects popular browsers such as Safari, Google Chrome, or Mozilla Firefox. After penetration, it sets http://tab.fileconvertermaster.com/ web page as default search engine of the browser. The new one looks like an ordinary search page, plus it has an additional feature allowing users to convert files directly on this page. However, that’s just a trick to attract users. This fake search engine starts to display a huge amount of advertising (pop-ups, banners, coupons, links to ad sites, and so on) that can appear at any time during your browser. This hijacker can significantly reduce the performance of your browser, increase traffic and transfer your personal information and browsing history to third parties. Moreover, this hijacker changes browser settings and modifies search results. That is why if you find File Converter Master on your device, then you urgently need to remove it as soon as possible.
