How to remove the SkillsRefer adware and the ads it delivers

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

What kind of application is SkillsRefer?

While inspecting new file submissions to the VirusTotal site, we discovered the SkillsRefer application. After analyzing this piece of software, we determined that it is adware. SkillsRefer belongs to the AdLoad malware family. This app is designed to run intrusive advertisement campaigns.

SkillsRefer adware

SkillsRefer adware overview

Adware stands for advertising-supported software. It operates by displaying ads on various interfaces. This third-party graphical content (e.g., pop-ups, coupons, overlays, etc.) primarily promotes online scams, unreliable/harmful software, and even malware. Once clicked on, some intrusive adverts can execute scripts to perform stealthy downloads/installations.

It is noteworthy that while legitimate content may be encountered through these advertisements – it is highly unlikely to be promoted by its developers or other official parties. It is most probable that this promotion is undertaken by scammers who abuse the products' affiliate programs to acquire illegitimate commissions.

Advertising-supported software might not deliver intrusive advert campaigns if the browser/system or user geolocation is incompatible, specific websites are not visited, or other conditions are unsuitable. Even if SkillsRefer does not display ads – its presence on a system endangers device/user safety.

While AdLoad applications often have browser-hijacking qualities, we did not observe these traits while testing the SkillsRefer app.

Adware typically has data-tracking abilities, and SkillsRefer may have them as well. Information of interest can include: visited URLs, viewed webpages, searched queries, Internet cookies, personally identifiable details, log-in credentials (usernames/passwords), credit card numbers, etc. The collected data can then be sold to third-parties or otherwise abused for profit.

To summarize, the presence of advertising-supported software like SkillsRefer on devices may result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of adware-type apps; SectionOperationSoftwareSkillMatrix, and ShoutSystem are merely a few examples.

Advertising-supported software usually appears legitimate and offers "handy" functionalities. These functions rarely work as promised, and in most cases – they do not work at all. Keep in mind that even if an app or an extension operates as indicated by its promotional material – that is not irrefutable proof of either legitimacy or safety.

How did SkillsRefer install on my computer?

The bundling marketing method – packing ordinary program installers with unwanted/malicious supplements – is used to distribute adware.

Downloading from untrustworthy sources (e.g., freeware and third-party websites, P2P sharing networks, etc.) and rushing through installation processes (e.g., using "Easy/Express" settings, etc.) – increase the risk of allowing bundled content into the device.

Adware can also have "official" promotional pages, and it is pushed through scam sites. Users mainly enter these webpages via redirects caused by misspelled URLs, websites that utilize rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening abilities).

Furthermore, advertising-supported software is proliferated by intrusive adverts. Upon being clicked, intrusive advertisements can execute scripts to perform downloads/installations without user consent.

How to avoid installation of adware?

We highly recommend researching software and downloading it only from official/verified channels. When installing, it is important to read terms, explore available options, use the "Custom" or "Advanced" settings, and opt out of all additions (e.g., apps, extensions, tools, features, etc.).

We advise being cautious while browsing since fake and malicious online content usually appears legitimate and harmless. For example, while intrusive ads may look innocuous – they redirect to unreliable and questionable websites (e.g., gambling, scam-promoting, pornography, adult dating, etc.).

In case of encounters with such adverts/redirects, check the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with SkillsRefer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
