How to uninstall the ExtendedField adware?
Written by Tomas Meskauskas on (updated)
What is ExtendedField?
ExtendedField is a piece of rogue software. It is classified as adware and has browser hijacker traits. ExtendedField operates by delivering intrusive advertisement campaigns and modifying browser settings to promote fake search engines.
Since most users download/install ExtendedField unintentionally, it is also categorized as a PUA (Potentially Unwanted Application). Additionally, apps within this category (adware and browser hijackers included) typically collect browsing-related and other sensitive information.
It is noteworthy that ExtendedField has been observed being distributed via fake Adobe Flash Player updates. Illegitimate software updaters/installers are notorious for proliferating PUAs and even malware (e.g., trojans, ransomware, etc.).
Adware delivers pop-ups, banners, surveys, coupons, full-page/full-screen, and other intrusive adverts. This third-party graphical content is typically displayed on any visited website and/or different interfaces.
Aside from severely crippling the browsing experience (by limiting webpage visibility and slowing down browsing speed), the delivered ads endanger device and user safety. Intrusive advertisements promote (redirect to) various sale-based, unreliable, misleading, deceptive/scam, compromised, and malicious sites.
Furthermore, some of these ads can be triggered (by being clicked) to execute scripts designed to download/install software (e.g., PUAs) without user permission. Browser hijackers assign fake web searcher addresses as browsers' homepage, default search engine, and new tab/window URLs.
Hence, with such a piece of software installed: every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. Illegitimate search engines usually cannot provide search results, so they redirect to Google, Yahoo, Bing, and other genuine ones.
Browser hijackers can reset any changes users try to make to their browsers and/or restrict/deny access to the browser settings outright. Therefore, recovering a hijacked browser is impossible without removing the software affecting it.
What is more, most PUAs have data tracking abilities. Information of interest includes: URLs visited, pages viewed, search queries typed, IP addresses/ geolocations, personally identifiable details, etc.
The collected data is then shared with and/or sold to third-parties (potentially, cyber criminals). In summary, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft. To protect device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

OriginalUnitValue, BoostConsole, FlexibleSector, SimpleProjectSearch - are some examples of adware-type applications. They look legitimate and harmless, enticing users into download/installation with various "useful" features.
However, the functions seldom work as advertised, and in most cases - they do not work at all. In fact, this is true of nearly all PUAs. The sole goal of unwanted software is to generate revenue for the developers.
Therefore, instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, hijack browsers, cause redirects, and collect private information.
How did ExtendedField install on my computer?
PUAs are distributed through download/installation setups of other products. This false marketing technique of packing regular software with unwanted or malicious additions - is termed "bundling".
Rushed download/installation processes (e.g., ignored terms, skipped steps, etc.) increase the risk of unintentionally allowing bundled content into the device.
Once clicked on, intrusive adverts can execute scripts to stealthily download/install PUAs. Some of these applications may also have "official" promotional/download pages.
How to avoid installation of potentially unwanted applications?
It is recommended to research software before download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources.
Since dubious download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer harmful and bundled content.
When downloading/installing, it is advised to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, features, and so forth. Intrusive advertisements appear ordinary and innocuous; however, they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with such adverts and/or redirects, the device must be checked and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with ExtendedField, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
