What is Fast Browser Search?

It is a potentially unwanted program (PUP) that hijacks your web browser and re-directs your homepage to its own search engine. It also changes the default search engine on your browser so that it uses Fast Browser Search. 

If you use the search engine to search for anything, Fast Browser Search will collect data including your IP address, browser, and the search terms you use. It will also display adverts and if you click on those, you’ll generate revenue for the distributors of the malware. In addition, it is likely that it will slow down your Mac and could conflict with other applications and processes. In this article, we’ll show you how to get rid of Fast Browser Search.

How did it get onto my Mac?

The most likely route is that it came bundled with other software you downloaded from a free software download site. Most of those sites use proprietary download managers that bundle other software with the program you chose to download. Often, this software includes PUPs and other malware. So you should avoid using sites that have their own download managers.
