How to remove AccessibleSkill from Mac?

What is AccessibleSkill?

Adware is a software that serves advertisements. However, AccessibleSkill does not only that, it also collects sensitive information and changes certain browser settings. Basically, AccessibleSkill functions not only as adware but also as a browser hijacker. Typically, users download and install apps of this type unintentionally, for this reason they are called potentially unwanted applications (PUAs).

AccessibleSkill adware

Some examples of types of ads that apps like AccessibleSkill serve are pop-up ads, banners, coupons, surveys. It is common that by clicking those ads users allow them to open questionable websites. In some cases by doing that users trigger unwanted downloads or even installations. Although, it happens only when ads are designed to execute certain scripts. As mentioned in the introduction, AccessibleSkill functions as a browser hijacker. It means that it changes browser settings such as the address of a default search engine, homepage and/or new tab to an address of some fake search engine. Usually search engines of this type do not generate unique results - they provide results generated by some other search engine (e.g., Google, Yahoo). It is worthwhile to mention that the changes made by a browser hijacker can be undone only when it is no longer installed. Another problem with AccessibleSkill is that it can read credit card details, passwords, telephone numbers and some other sensitive information. Such information could be misused by its developers for various malicious purposes. For example, they could use it to make fraudulent purchases, transactions, steal identities, personal accounts. Also, they could sell collected data to third parties, potentially cyber criminals. Therefore, AccessibleSkill should never be downloaded and installed.

To summarize, AccessibleSkill's users could become victims of identity theft, lose access to various accounts, suffer monetary loss, and/or have other problems related to online privacy, browsing safety, etc. Users who have this app installed on a browser and/or the operating system should remove it as soon as possible. More examples of apps like AccessibleSkill are LearningActivity, MarketService and AnalyticParameter.

How did AccessibleSkill install on my computer?

Typically, users download and install PUAs unintentionally: by clicking deceptive advertisements that are designed to execute certain scripts or together with other programs (when they are distributed by a deceptive marketing method called "bundling"). To be more precise, when PUAs are included in various download and/or installation setups of other programs as extra offers. Usually information about included apps is provided in "Custom", "Advanced" and other similar settings of the aforementioned setups. Users who download and/or install programs without changing those settings download and/or install included PUAs too.

How to avoid installation of potentially unwanted applications?

It is advised to download programs (and files) from official websites and via direct download links. Other sources like third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, etc., can be used to distribute/promote PUAs. Third party installers can be used for that too. Also, it is recommended not to leave "Advanced", "Custom" or other settings of any download and installation setup unchecked - it is common that those settings can be used to decline offers to download and/or install unwanted applications. Intrusive ads that are displayed on untrustworthy, shady pages should not be clicked as well - more often than not those ads are designed to open various questionable websites. Sometimes they are capable of causing downloads, installations of potentially unwanted, or even malicious apps by executing certain scripts. Any unwanted apps (extensions, add-ons or plug-ins) that are already installed on a web browser should be removed. The same applies to programs of this kind that are installed on the operating system. If your computer is already infected with AccessibleSkill, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
