How to remove PrimaryFunction from Mac computers

What is PrimaryFunction?

PrimaryFunction is a rogue application categorized as adware. It operates by running intrusive advertisement campaigns, however, this app also has browser hijacker characteristics. PrimaryFunction modifies browser settings and promotes fake search engines. For example, it promotes Safe Finder through akamaihd.net. Additionally, most adware infections and browser hijackers can track and record browsing-related data. Since few users download/install PrimaryFunction intentionally, it is also classified as a Potentially Unwanted Application (PUA).

PrimaryFunction adware enables the placement of pop-ups, banners, coupons, surveys and other ads on any visited web page. These diminish the browsing experience, as they overlay page content and reduce browsing speed. When clicked, intrusive ads redirect to untrusted, deceptive and malicious sites. They can even execute scripts to stealthily download/install rogue software (e.g. PUAs). This application hijacks browsers by reassigning the homepage, default search engine and new tab/window URLs to the addresses of fake search engines. With a browser hijacker installed, each search made via the URL bar and each new tab/window opened redirects to the address of a bogus search engine. Few of these fake tools can provide unique results, and so they typically redirect to (or cause redirection chains leading to) Google, Yahoo, Bing and other legitimate search engines. In the case of PrimaryFunction, the aforementioned actions redirect to akamaihd.net and then to Safe Finder, which in turns redirects to search.yahoo.com (a genuine search engine). Furthermore, access to the browser settings is limited or denied, and any permitted changes made are reset automatically. As with most software categorized as adware or browser hijackers, it is highly likely that PrimaryFunction has data tracking capabilities. They can monitor browsing activity (browsing and search engine histories) and collect personal information derived from it (IP addresses, geolocations and other vulnerable data). The gathered information is usually shared with third parties (potentially, cyber criminals) seeking to misuse it for profit. In summary, the presence of these unwanted apps on systems can lead to various infiltration and infections, serious privacy issues, financial loss and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

GroupSource, DynamicWindow and SmartSignalSearch are some examples of other adware-type apps. These may seem legitimate and useful, however, the features promised are often nonoperational. In fact, this applies to all PUAs, which have just one purpose: to generate revenue for the developers. PUAs simply cause unwanted redirects, modify browsers, deliver intrusive ad campaigns and track private data.

How did PrimaryFunction install on my computer?

PUAs are often downloaded/installed with other products. "Bundling" is the name of this deceptive marketing technique of pre-packing regular apps with unwanted or malicious software. By rushing through download/installation processes (e.g. ignoring terms, skipping steps and sections, using presets, etc.), many users risk unintentionally installing bundled additions. Certain PUAs have "official" download websites. Intrusive ads proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs, without users' consent.

How to avoid installation of potentially unwanted applications

You are strongly advised to research all products prior to download/installation or purchase. All downloads should be performed only from official and trustworthy sources. Unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders should be avoided, since they can offer bundled content. Download/Installation processes should be treated with caution. Read the terms, explore available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, functions and other additions. Intrusive advertisements may seem normal and innocuous, however, they can redirect to highly dubious pages (e.g. gambling, pornography, adult-dating, etc.). If you encounter these ads/redirects, check the system and immediately eliminate all suspect applications and browser extensions/plug-ins. If your computer is already infected with PrimaryFunction, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
