How to remove the FieldIndexer unwanted application
Written by Tomas Meskauskas on (updated)
What is FieldIndexer?
FieldIndexer is classified as adware, since it feeds users with various advertisements. Commonly, apps of this type collect information relating to users' browsing habits, and this might also be the case with FieldIndexer. Additionally, it could be designed to promote a fake search engine (function as a browser hijacker).
In most cases, users download and install adware inadvertently and, for this reason, the programs are classified as potentially unwanted applications (PUAs).
Typically, applications such as FieldIndexer generate revenue for the developers by serving various advertisements (e.g., banners, coupons, surveys, pop-up ads). Users who click these ads often arrive at dubious web pages. Sometimes the ads cause download and/or installation of PUAs, when the ads execute certain scripts.
Furthermore, adware can be designed to collect browsing data. For example, IP addresses, geolocations, entered search queries, addresses of visited websites. They can also gather sensitive information. The data could be sold to third parties (potentially, cyber criminals) or misused to generate revenue in other ways.
As mentioned, FieldIndexer might function as a browser hijacker - it could be designed to change browser settings. Typically, browser hijackers promote fake search engines by assigning their address as the homepage, default search engine and address of a new tab.
Users often cannot remove the addresses promoted by browser hijackers and/or adware from browser settings, unless they uninstall the rogue app. Therefore, FieldIndexer should never be downloaded or installed.

Quite often apps such as FieldIndexer are advertised as legitimate applications that supposedly improve the browsing experience, include various features, etc., however, most are useless. Furthermore, installation can result in problems relating to online privacy, browsing safety or even identity theft.
If this app is installed on your browser and/or operating system, remove it immediately. Some examples of other apps similar to FieldIndexer are OperativeDevice, SkilledOrigin and OptimalSync.
How did FieldIndexer install on my computer?
Users often download and install adware (and other PUAs) through the set-ups of other programs. Commonly, apps of this type are included as 'additional offers' with related information in settings such as "Custom", "Advanced", and "Manual". Many people fail to check and change these settings when they download and install their programs.
By leaving them unchanged, they allow PUAs to infiltrate with regular software. This PUA distribution method is called "bundling". Note that unwanted downloads and installations can also be caused by clicking deceptive advertisements that run certain scripts.
How to avoid installation of potentially unwanted applications
All software should be downloaded from official websites and via direct links. Sources/tools such as 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 to download/install files or programs, since they are commonly used to distribute PUAs.
Check all "Custom", "Advanced" and other settings, and decline offers to download or install unwanted software before completing the process. Do not click advertisements that are displayed on dubious websites, as they can open untrusted websites or download and install unwanted, potentially malicious software.
Remove all unwanted, suspicious extensions, add-ons and plug-ins that are installed on the browser. Also remove software of this kind that is installed on the operating system. If your computer is already infected with FieldIndexer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
