How to remove ExpandedSkill adware from Mac computers

What is ExpandedSkill?

ExpandedSkill is rogue software. This application is classified as adware, which also possesses browser hijacker characteristics. Following successful infiltration, ExpandedSkill runs intrusive advertisement campaigns, makes alterations to browser settings and promotes fake search engines. Additionally, most adware and browser hijackers have data tracking capabilities, which are employed to monitor users' browsing activity. Due to the dubious methods employed to proliferate, ExpandedSkill, it is also classified as a Potentially Unwanted Application (PUA).

ExpandedSkill adware

Adware delivers pop-ups, banners, coupons, surveys, full-page and other intrusive ads. These significantly diminish the browsing experience, as the ads overlay web page content and reduce browsing speed. As well as being a nuisance, intrusive advertisements are also harmful. When clicked, they can redirect to various untrusted/malicious websites and some can even stealthily download/install rogue software (e.g. PUAs). Browser hijackers reassign the homepage, default search engine and new tab/window URLs to the addresses of fake search engines. To elaborate on how this affects browsing, each new browser tab/window opened and web search made via the URL bar redirects to the promoted address. Rogue search engines are typically unable to provide unique results, and so they redirect to Yahoo, Bing, Google and other genuine sites. Browser hijackers can restrict/deny access to the browser settings and/or reset any permitted changes made. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. Furthermore, most PUAs can track data. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and extract personal information from it (IP addresses, geolocations and other details). The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals). In summary, the presence of unwanted software on devices can result in system infections, financial loss, serious privacy issues and even identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

CoordinatorBoostExtendedLibraryExtendedProcesser and DynamicImprovment are some examples of other aware-type applications. They may seem legitimate and offer a wide variety of "useful" features, but despite how good the features promised may sound, they are rarely operational. In fact, this applies to most PUAs. The only purpose of these unwanted apps is to generate revenue for the developers. PUAs run intrusive ad campaigns, cause redirects, hijack browsers and track sensitive data.

How did ExpandedSkill install on my computer?

PUAs are proliferated via the download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling". Rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.) increases the risk of unintentionally allowing dangerous and/or bundled content into the system. Intrusive advertisements can infiltrate PUAs into devices as well. Once clicked, they can execute scripts to make stealthy downloads/installations. Certain PUAs also have "official" download websites.

How to avoid installation of potentially unwanted applications

You are advised to research all products before download/installation and/or purchase. All downloads must be done from official and verified sources. Unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders are untrusted, as they can offer bundled content. When downloading/installing, read the terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out of additional apps, tools, features, etc. Intrusive ads may seem legitimate and innocuous, however, they can redirect to highly dubious web pages (e.g. gambling, pornography, adult-dating, and so on). If you encounter these ads or redirects, inspect the system and remove all dubious applications and browser extensions/plug-ins without delay. If your computer is already infected with ExpandedSkill, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
