How to remove AccessibleBoost adware from Mac?

What is AccessibleBoost?

AccessibleBoost is an adware-type application with browser hijacker qualities. It runs intrusive advertisement campaigns, makes modifications to browser settings and promotes a fake search engine. AccessibleBoost promotes z6airr.com. It is not unlikely that AccessibleBoost spies on browsing activity, as most adware-types and browser hijackers have such data tracking abilities. Due to the dubious techniques used to distribute AccessibleBoost, it is deemed to be a PUA (Potentially Unwanted Application). One of the proliferation methods used for this app is distribution via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are used to spread not only PUAs but also malware (e.g. trojans, ransomware, etc.).

AccessibleBoost adware

Adware enables the placement of pop-ups, banners, coupons, surveys and other intrusive advertisements - typically, on any visited website. These adverts overlay webpage content and limit the browsing speed. Additionally, when intrusive ads are clicked on, they redirect to various unreliable/malicious sites and some can even execute scripts to stealthily download/install software (e.g. PUAs). Browser hijackers reassign browsers' homepage, default search engine and new tab/window URL - to the addresses of fake web searchers. Hence, with AccessibleBoost installed: every new browser tab/window opened and search query typed into the URL bar - redirect to z6airr.com. Fake search engines are seldom capable of generating search results, so they redirect to Google, Yahoo, Bing and other legitimate ones. Browser hijackers can undo any changes users attempt to make to their browsers and/or restrict/deny access to the browser's settings. What is more, most PUAs can track data. They monitor browsing history (URLs visited, pages viewed, search queries typed, etc.) and gather sensitive information extracted from it (IP addresses, geolocations and other details). The collected data usually contains personally identifiable information and PUA developers share/sell it to third parties (potentially, cyber criminals). To summarize, the presence of unwanted software on devices can result in system infections, financial losses, severe privacy issues and even identity theft. To ensure device integrity and user safety, all suspicious applications and browser extensions/plug-ins immediately upon detection.

InitiatorFieldSectionIndexerCapitalCharacterSearch - are some examples of software within the adware category. It appears legitimate and useful. Users are enticed into download/installation with a wide variety of functionalities. However, the promised features are rarely operational. In fact, this applies to nearly all PUAs. The sole purpose of unwanted applications is to generate revenue for the developers; to users - they have no real value and can instead cause serious issues. PUAs are designed to run intrusive advert campaigns, modify browsers, cause redirects and track private data.

How did AccessibleBoost install on my computer?

PUAs are distributed via download/installation setups of other products. "Bundling" is the term used to describe this false marketing tactic of packing regular with unwanted or malicious additions. Rushed download/installation processes (e.g. ignored terms, used presets, etc.) - increase the risk of unintentionally allowing bundled content into the system. Select 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 permission.

How to avoid installation of potentially unwanted applications?

It is strongly advised to research products prior to download/installation and/or purchase. All downloads have to be done from official and verified sources. Dubious download channels, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders. When downloading/installing, it is important to read terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive ads appear ordinary, however they redirect to gambling, pornography, adult-dating and various other highly questionable sites. Should users encounter adverts and/or redirects of this kind, they must inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins from it. If your computer is already infected with AccessibleBoost, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
