How to remove FullBrowser from Mac computers

What is FullBrowser?

FullBrowser is advertised as a useful application that enhances the browsing experience by providing fast searches, accurate search results, etc. In fact, this application is adware, a type of software that displays unwanted advertisements. These apps often gather details relating to users' browsing habits. Furthermore, most people download and/or install this adware unintentionally. Therefore, these apps are also known as potentially unwanted applications (PUAs).

FullBrowser adware

Adware-type apps feed users with intrusive ads - generally, these are pop-ups, coupons, surveys, banners, and so on. People who click them are often redirected to dubious, potentially malicious websites. In some cases, the ads run scripts that download and install PUAs. In any case, it is not safe to click any ads displayed by adware. The same applies to ads displayed on dubious, deceptive websites. Furthermore, many PUAs collect details such as IP addresses, entered search queries, URLs of visited pages, geolocations, and other data relating to browsing activities. It is possible that installed PUAs might also record sensitive information. The people behind these apps (developers) share the information with third parties who misuse it to generate revenue. Some of these people might include cyber criminals. Thus, having adware (or other PUAs) installed can lead to identity theft or other problems relating to browsing safety, online privacy, etc. You are strongly advised not to use adware - uninstall it immediately.

Examples of other adware-type apps that belong to the same family as FullBrowser include ApplicationEvents, StudyDisplay, and AssistEngine. Typically, these apps display ads and gather various details to enable developers to generate revenue. Unfortunately, from the user's perspective, they are often useless and simply cause problems.

How did FullBrowser install on my computer?

Even when PUAs (including adware) are available for download on their websites, most people download and install them inadvertently by clicking deceptive ads or when downloading/installing regular software. PUAs are commonly included in the set-ups of other (usually free) software, however, related information is not properly disclosed. Developers hide the details in "Custom", "Advanced" and other settings of download or installation set-ups. Furthermore, many users give PUAs permission to be downloaded/installed through the setups of other programs when they leave the settings unchanged.

How to avoid installation of potentially unwanted applications

The safest way to download software and files it using official websites. Do not trust torrent clients, eMule and other Peer-to-Peer networks, third party downloaders, installers, dubious pages, or other channels/tools of this kind - they are often used to distribute unwanted apps. Many download or installation set-ups include "Custom", "Advanced" and other similar settings - check these carefully and deselect offers to download or install unwanted programs. Intrusive ads should not be trusted, especially if they are displayed on dubious web pages relating to adult dating, gambling, pornography, torrents, and so on. If a browser causes redirects to untrustworthy sites or shows unwanted ads, remove all unwanted, suspicious extensions, add-ons, and plug-ins installed. Also remove programs of this type installed on the operating system. If your computer is already infected with FullBrowser, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
