How to remove DominantPartition adware from Mac?

What is DominantPartition?

DominantPartition is an adware-type app with browser hijacker traits. This application operates by running intrusive advertisement campaigns and making changes to browser settings - in order to promote fake search engines. Additionally, most adware-types and browser hijackers collect browsing-related information. Since users typically download/install DominantPartition inadvertently, it is also classified as a PUA (Potentially Unwanted Application). This app has been observed being spread via fake Adobe Flash Player updates. It is worth noting that illegitimate software updaters are employed to proliferate not only PUAs but also trojans, ransomware and other malware.

Adware delivers pop-ups, banners, coupons, surveys, full-page and other intrusive advertisements. These ads seriously diminish the browsing experience, by overlaying page content and slowing down the browsing speed. Furthermore, intrusive advertisements are deemed to be dangerous. Since upon being clicked, they redirect to various unreliable/malicious sites and some can even stealthily download/install software (e.g. PUAs).

Browser hijackers reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake web searchers. Hence, with this browser hijacker installed: new browser tabs/windows opened and web searches done via the URL bar - redirect to the promoted address. Illegitimate search engines are seldom able to provide search results, so they usually redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other genuine ones. Browser hijackers can also restrict/deny access to browser settings and/or undo any permitted changes made.

Most PUAs (adware and browser hijackers included) have data tracking abilities. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). The collected data is then shared with and/or sold to third parties (potentially, cyber criminals). To summarize, presence of data-tracking software on devices can lead to system infections, severe privacy issues, financial losses and even identity theft. Therefore, it is strongly advised to remove all dubious applications and browser extensions/plug-ins immediately upon detection.

FPMPlayerProductChannelInitialProgramElementaryTypeActivityElement - are some examples of other apps within the adware category. They appear legitimate and offer various "handy" features. However, the promised functionalities rarely work. In fact, this applies to nearly all PUAs. The sole goal of unwanted software is to generate profit at user expense. Hence, instead of delivering on any promises, PUAs can run intrusive ad campaigns, hijack browsers, cause redirects, and collect private data.

How did DominantPartition install on my computer?

PUAs are distributed through download/installation setups of other programs. "Bundling" is the name of this deceptive marketing method of packing regular software with unwanted or malicious additions. Rushed download/installation processes (e.g. ignored terms, skipped steps and sections) increase the risk of unintentionally allowing bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user consent. PUAs can also have "official" download webpages.

How to avoid installation of potentially unwanted applications?

It is recommended to always research software before download/installation and/or purchase. All downloads must be done from official and verified sources. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - are considered to be untrustworthy, due to commonly offering harmful and/or bundled content. When downloading/installing, it is advised to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, etc. It is just as important to exercise caution when browsing. Intrusive adverts appear legitimate, however they redirect to highly questionable sites (e.g. gambling, adult-dating, pornography, and many others). In case of encounters with ads and/or redirects of this type, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with DominantPartition, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
