How to remove InitialSkill adware from Mac?

What is InitialSkill?

InitialSkill is a rogue application, which is categorized as adware and it possesses browser hijacker qualities. It operates by delivering intrusive advert campaigns and by making modifications to browser settings - in order to promote fake search engine. Additionally, it is highly likely that InitialSkill spies on users' browsing activity - as it is common for both adware and browser hijackers. Most users download/install InitialSkill inadvertently, due to this - it is considered to be a PUA (Potentially Unwanted Application) as well. One of the questionable tactics used for this app's distribution is proliferation via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are employed not only to spread various PUAs but also trojans, ransomware and other malware.

Adware enables the placement of pop-ups, banners, coupons, surveys and other intrusive ads - typically, on any visited site. The delivered advertisements severely diminish the browsing quality, as they limit the browsing speed and webpage visibility. Furthermore, once clicked on, intrusive adverts redirect to a variety of untrustworthy/malicious websites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, every new browser tab/window opened and search query typed into the URL bar - redirect to the address of the promoted illegitimate search engine. These web searchers are seldom able to provide search results, so they redirect (or cause redirection chains leading) to Yahoo, Bing, Google and other legitimate search engines. To ensure persistence, browser hijackers can restrict/deny access to the browsers' settings and undo any permitted changes made. Therefore, recovering a hijacked browser is impossible - without removing the software affecting it. What is more, most PUAs (adware and browser hijackers included) have data tracking abilities. Information of interest includes: visited URLs, viewed pages, searched queries, IP addresses, geolocations, and other personally identifiable data. The gathered information is then monetized by being shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses and even identity theft. To protect device integrity and user privacy, all suspicious applications and browser extensions/plug-ins must be eliminated without delay.

CleanParameterTrustedAnalog and HerculesLookup are a few examples of other apps within the adware category. They appear ordinary and harmless. Users are enticed into download/installation with offers of various "handy" functionalities. However, the advertised features are seldom operational. This applies to practically all PUAs. The only goal of unwanted software is to generate revenue for the developers; to users - it has no real value and may cause severe problems. Instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, hijack browsers, cause redirects and collect private data.

How did InitialSkill install on my computer?

PUAs can be downloaded/installed alongside other software. This false marketing tactic of packing regular programs with unwanted or malicious additions - is termed "bundling". By rushing through download/installation processes (e.g. by ignoring terms, using "Easy/Express" settings, etc.) - users risk unintentionally allowing bundled content into their devices. Intrusive adverts proliferate PUAs as well. Upon being clicked, the ads can execute scripts to download/install these applications without user permission. Select PUAs have "official" promotional sites, from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

It is advised to research software products before download/installation and/or purchase. All downloads must be done from official and trustworthy sources. Dubious download channels, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer harmful and/or bundled content. When downloading/installing, it is recommended to read terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. It is just as important to exercise caution when browsing. Intrusive advertisements appear legitimate, however they redirect to unreliable and questionable webpages (e.g. gambling, adult-dating, pornography, and so on). In case of encounters with ads and/or redirects of this kind, users must inspect their devices and immediately remove all suspect applications and browser extensions/plug-ins detected. If your computer is already infected with InitialSkill, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
