How to remove FieldIndexer from Mac?

What is FieldIndexer?

Since FieldIndexer is classified as adware, it feeds users with various advertisements. It is common that apps of this type are designed to collect information related to user's browsing habits, therefore, FieldIndexer might be one of those apps. Additionally, it could be designed to promote some fake search engine (function as a browser hijacker). In most cases users download and install adware inadvertently (unknowingly). For this reason they are called potentially unwanted applications (PUAs).

FieldIndexer adware

Typically, applications like FieldIndexer are designed to generate revenue for their developers by serving various advertisements (e.g., banners, coupons, surveys, pop-up ads). Quite often users who click those ads end up on questionable pages. Sometimes such ads can cause download and/or installation of some PUA, although, it happens only when those ads are designed to execute certain scripts. Furthermore, adware can be designed to collect browsing data, for example, IP addresses, geolocations, entered search queries, addresses of visited websites. Also, they can be designed to gather sensitive information. Moreover, gathered data could be sold to third parties (potentially cyber criminals) or misused to generate revenue in other ways. As mentioned in the introduction, FieldIndexer my function as a browser hijacker - it could be designed to change browser settings. Typically, browser hijackers promote some fake search engine by making its address as a homepage, default search engine and address of a new tab. Quite often users cannot remove the address promoted by a browser hijacker and/or adware from browser settings unless they uninstall that app. These are the main reasons why FieldIndexer should never be downloaded and installed.

Quite often apps like FieldIndexer are advertised as legitimate applications that supposed to improve browsing experience, include some features, etc. Nevertheless, most of them are useless, besides, their installation may result in problems related to online privacy, browsing safety, or even identity theft. If such app is installed on a browser and/or operating system, then it should be uninstalled as soon as possible. A couple of examples of other apps like FieldIndexer are OperativeDevice, SkilledOrigin and OptimalSync.

How did FieldIndexer install on my computer?

Users often download and/or install adware and other PUAs through download and/or installation setups of other programs. It is common that apps of this type are included in setups as additional offers and information about it can be found in their settings like "Custom", "Advanced", "Manual". Not all people check and change those settings when they download and install programs. By leaving them unchanged they allow for PUAs to be downloaded or installed alongside with wanted software. This distribution method of PUAs is called "bundling". It is worthwhile to mention that unwanted downloads and installations can be caused by clicking deceptive advertisements too. Those ads cause it by running certain scripts.

How to avoid installation of potentially unwanted applications?

All software should be downloaded from official websites and via direct links. Sources, tools like Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, third party downloaders (and installers), free file hosting pages, etc., should not be used neither to download or install files, or programs. It is common that they are used to distribute PUAs. Furthermore, download and installation setups should be always checked for "Custom", "Advanced" and other settings, offers to download and/or install unwanted software should be declined before completing downloads and installations. Advertisements that are displayed on shady websites should not be clicked as well - they can be designed to open untrustworthy websites or download, install unwanted, potentially malicious software. Unwanted, suspicious extensions, add-ons or plug-ins that are installed on a browser should be removed. Software of this kind that is installed on the operating system should be uninstalled too. If your computer is already infected with FieldIndexer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
