How to remove ExtendedTool adware from Mac?

What is ExtendedTool?

ExtendedTool is a piece of rogue software, classified as adware with browser hijacker traits. This application operates by delivering intrusive advertisement campaigns, making alterations to browser settings and promoting fake search engines. ExtendedTool promotes akamaihd.net via Safe Finder. Most software of these types have data tracking abilities and it is highly likely that ExtendedTool does as well. Additionally, due to the questionable methods used to distribute this app, it is also deemed to be a PUA (Potentially Unwanted Application).

ExtendedTool adware

Adware enables the placement of pop-ups, banners, coupons and other intrusive ads - typically, on any visited website. Presence of adware-type software on browsers/systems seriously diminishes browsing quality. These adverts redirect to various dubious/malicious sites and some can stealthily download/install software (e.g. PUAs). Browser hijackers reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of illegitimate web searchers. Hence, every single browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. ExtendedTool promotes (through akamaihd.net) Safe Finder in this manner. Fake search engines are usually unable to generate search results, so they tend to redirect to Yahoo, Google, Bing and other legitimate ones. Furthermore, any changes users attempt to make to their browsers can be automatically reset, if access to the browser's settings is permitted at all. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. As mentioned in the introduction, most adware and browser hijackers can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). The collected data is typically shared with and/or sold to third parties (potentially, cyber criminals), seeking to likewise misuse it for profit. In summary, presence of unwanted apps on devices can lead to system infections, financial losses, serious privacy issues and even identity theft. To ensure device integrity and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

DivisionFormatAssistiveRecordAssistiveUnit - are some examples of other adware-type apps. They appear ordinary and harmless. Users are enticed into download/installation with offers of various "useful" features. However, the advertised functionalities are rarely operational. This applies to practically all PUAs. The sole purpose of unwanted software is to generate revenue for the developers; to users - they have no real value and can instead cause serious issues. Therefore, instead of delivering on any promises, PUAs run intrusive advertisement campaigns, modify browsers, cause redirects and collect private data.

How did ExtendedTool install on my computer?

PUAs are distributed via download/installation setups of other software. This false marketing technique of packing regular products with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps and sections, etc.) - users risk inadvertently allowing bundled content into the system. Some PUAs have "official" promotional webpages, from which they can be downloaded. Intrusive advertisements proliferate these applications as well. Once clicked on, they can execute scripts to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

All products should be researched before download/installation and/or purchase. It is recommended to only download from official and verified sources. Unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content; due to this, these sources are deemed to be untrustworthy. When downloading/installing, it is important to read terms, study all available options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive ads appear legitimate, however they redirect to unreliable and malicious websites (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with such adverts/redirects of this kind, users must inspect the system and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with ExtendedTool, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
