How to remove AccessibleTask adware from the operating system?

Also Known As: Ads by AccessibleTask
Type: Mac Virus
Damage level: Medium

What is AccessibleTask?

AccessibleTask is a piece of rogue software. It is classified as adware, and it has browser hijacker qualities.

Following successful installation, this app delivers intrusive advertisement campaigns and promotes fake search engines through modifications to browser settings. Additionally, AccessibleTask likely has data tracking abilities, as they are common for adware and browser hijackers.

Due to the questionable methods used to distribute AccessibleTask, it is also classified as a PUA (Potentially Unwanted Application). One of the techniques observed in use for this app is proliferation via fake Adobe Flash Player updates. It is noteworthy that illegitimate updaters/installers are used to spread not only PUAs but malware (e.g., trojans, ransomware, cryptominers, etc.) as well.

AccessibleTask adware in detail

Adware enables the placement of pop-ups, banners, surveys, coupons, and other intrusive adverts - on any visited website and/or different interfaced. The delivered ads severely diminish the browsing experience by limiting the browsing speed and overlaying webpage content.

Furthermore, intrusive advertisements pose a threat to device/user safety. Once clicked on, these adverts redirect to various untrustworthy/malicious websites, and some can stealthily download/install software (e.g., PUAs).

Browser hijackers assign fake web searcher addresses as browsers' homepage, default search engine, and new tab/window URLs. Hence, every single search query typed into the URL bar and new tab/window opened - redirect to the promoted address.

Fake search engines are seldom able to generate results, so they redirect to (or cause redirection chains ending with) Google, Yahoo, Bing, and other legitimate ones.

Browser hijackers can also reset any changes users try to make to their browsers. Alternatively, this software can restrict or deny access to the browser settings. Therefore, recovering a hijacked browser is impossible without removing the software affecting it.

Most PUAs (adware and browser hijackers included) have data tracking abilities. Information of interest includes: URLs visited, webpages viewed, search queries typed, IP addresses/ geolocations, personally identifiable details, and so on. The collected data is then shared with and/or sold to third-parties (potentially, cyber criminals).

To summarize, the presence of unwanted apps on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft. It is strongly advised to remove all suspicious applications and browser extensions/plug-ins without delay.

Adware in general

DesignDefaultTypeInitiatorStartEssentials, and CharacterSearch are some examples of adware-type apps. They appear ordinary and innocuous.

Adware entices users into download/installation with offers of various "useful" functionalities. However, the advertised features are rarely operational. In fact, practically all PUAs offer a broad range of functions, which do not work.

The sole goal of unwanted software is to generate profit for the developers. Therefore, instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, hijack browsers, force-open untrustworthy and malicious sites, and gather private data.

How did AccessibleTask install on my computer?

PUAs can be downloaded/installed together with other programs. This deceptive marketing technique of packing regular software with unwanted or malicious additions - is termed "bundling".

Rushed download/installation processes (e.g., skipped steps and sections, etc.) increase the risk of inadvertently allowing bundled content into the system.

Intrusive advertisements spread PUAs as well. Upon being clicked, the adverts can execute scripts to download/install these applications without user consent. PUAs may also have "official" promotional sites from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

It is recommended to research software products before download/installation and/or purchase. Furthermore, only official and trustworthy download channels. Dubious download sources, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - commonly offer harmful and bundled content.

When downloading/installing, it is advised to read terms, explore all possible options, use the "Custom/Advanced" settings, and opt-out from additional apps, tools, features, and so forth.

Intrusive advertisements appear legitimate and ordinary; however, they redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with AccessibleTask, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
