Danger level 3
Type: Potentially Unwanted Application


The web browser market is primarily shared by a few big web browsers that users employ daily. However, there are also an entire lot of other web browsers out there like eFast that could be customized and used by almost anyone. It seems like, with the simplicity of use, eFast could become the next best thing, but computer security experts say that it is a potentially unwanted program that thrives on third-party advertising. Third-party advertising is a type of advertising practice that requires your participation to be successful. Granted, the practice itself is not malicious, but if you do not remove eFast from your system, the chances are that soon enough you will be exposed to potential security threats.

eFast is one of the many browsers that are based on the Chromium engine. It is not the first Chromium browser we see, having dealt with Mustang Browser and TortugeBrowser previously. When you encounter a web browser that is built on the Chromium engine, it is possible that you can mistake it for being a supplementary edition of Google Chrome. That is why quite a lot of users trust this program at first, and they end up unwittingly revealing their web browsing habits to the third parties behind this application.

Our security researchers were not able to locate the official website for this application, so we can assume that most of the time eFast gets distributed in software packages. That is why users may think that eFast arrived at their systems with a Google Chrome update or something like that. However, the reality is that this web browser was probably installed on your PC when you downloaded some freeware app from a file sharing site. On top of that, it is possible that you installed several other unnecessary applications, as freeware apps usually travel in packs. Thus, perhaps you should scan your PC with a computer security program of your choice to detect all the unwanted programs.

We believe that you will find eFast rather annoying as this browser removes Google Chrome shortcuts from your desktop and the quick start menu (assuming you have had Google Chrome set as your default browser). Also, eFast modifies your settings in a way that it becomes your default web browser, and each time you surf the web with it, the program displays commercial advertisements. The good thing is that the advertisements appear only in this program, and this feature does not affect the other browsers that you have. The bad thing is that eFast is very eager in redirecting you to its affiliated websites because it needs to make money.

You need to protect your privacy and your personal information from potential scam and exploitation schemes. For that, you definitely need to delete eFast from your computer. Open Control Panel and uninstall the application manually. That should be enough to terminate this program, but, on the other hand, you must not forget that your computer could be full of other unnecessary applications.

Run a full system scan with the SpyHunter free scanner to determine whether you have any serious threats on-board. Should any unwanted programs be detected, delete them automatically and then take all the precaution measures to bar similar apps from entering your PC.
