How to remove AdjustableSkill adware from Mac?

What is AdjustableSkill?

AdjustableSkill is an adware-type application with browser hijacker traits. Following successful installation, it runs intrusive advertisement campaigns (i.e. delivers various ads), makes alterations to browser settings and promotes fake search engines. AdjustableSkill promotes z6airr.com, however on Google Chrome browsers - it promotes search.navigationbuffer.com. Additionally, most adware-types and browser hijackers have data tracking abilities, which are employed to spy on users' browsing activity. Due to the dubious techniques used to proliferate AdjustableSkill, it is classified as a PUA (Potentially Unwanted Application). One of the methods used to distribute this app is via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are used to spread not just PUAs but trojans, ransomware and other malware as well.

AdjustableSkill adware

Adware delivers pop-ups, banners, coupons, full-page and other intrusive adverts. They severely diminish the browsing quality, since they overlay page content and restrict browsing speed. Furthermore, once clicked on, intrusive ads redirect to various 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, with such a piece of software installed: new browser tabs/windows opened and web search done via the URL bar - redirect to the promoted address. AdjustableSkill promotes z6airr.com or search.navigationbuffer.com - in this manner as well. Fake search engines are seldom capable of generating search results, so they redirect to (or cause redirection chains ending with) Yahoo, Bing, Google and other legitimate ones. Browser hijackers can also limit/deny access to the browser's settings and/or reset any permitted changes made. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. Most PUAs (adware and browser hijackers included) can monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The collected data is typically shared with and/or sold to third parties (potentially, cyber criminals). To summarize, presence of unwanted apps on devices can lead to system infections, financial losses, severe privacy issues and even identity theft. To ensure device and user safety, all suspect applications and browser extensions/plug-ins must be eliminated without delay.

NetProgress, PersonalSearch and PracticalRemote are a couple examples of other adware-type apps. They appear ordinary and innocuous. Users are enticed into download/installation with offers of various "useful" functionalities. However, despite how good the promised features may sound - they are rarely operational. In fact, this is true of nearly all PUAs. The only purpose of unwanted software is to generate revenue at user expense. Therefore, instead of delivering on any promises, PUAs run intrusive ad campaigns, hijack browsers, cause redirects and gather private data.

How did AdjustableSkill install on my computer?

PUAs are distributed through download/installation setups of other products. This deceptive marketing technique of packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, etc.) - increase the risk of inadvertently allowing dubious and/or bundled content into the system. Intrusive advertisements proliferate these applications as well. Upon being clicked, the ads can execute scripts to make downloads/installations without user permission. Some PUAs have "official" promotional sites, from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

It is highly recommended to research products prior to download/installation and/or purchase. Only official and verified download channels must be used. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content; due to this, these sources are deemed to be untrustworthy. When downloading/installing, it is advised to read terms, study all available options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, and so on. Intrusive adverts appear legitimate, however they redirect to questionable webpages (e.g. gambling, pornography, adult-dating, and many others). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspicious applications and browser extensions/plug-ins - immediately removed from it. If your computer is already infected with AdjustableSkill, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
