How to remove ExpandedTask adware from Mac?

What is ExpandedTask?

ExpandedTask is a piece of dubious software. It is categorized as adware, and it also has browser hijacker traits. This app operates by delivering intrusive advertisement campaigns and making alterations 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 ExpandedTask inadvertently, it is deemed to be a PUA (Potentially Unwanted Application).

ExpandedTask adware

Adware enables the placement of third party graphical content - usually on any visited website. The delivered content consists of pop-ups, banners, coupons, surveys, full-page, and other intrusive ads. They seriously diminish browsing quality by limiting webpage visibility and slowing down browsing speed. Furthermore, once clicked on, intrusive adverts redirect to untrustworthy/malicious sites and some can stealthily download/install software (e.g., PUAs).

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. Hence, with such a piece of software installed: 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 rarely able to provide search results, so they redirect to (or cause redirection chains ending with) Google, Bing, Yahoo, and other legitimate search engines. Browser hijackers can also reset any changes users try to make to their browsers and/or restrict/deny access to the browser settings. Therefore, recovering a hijacked browser is impossible without eliminating the software affecting it.

Most PUAs have data tracking abilities. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect 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). In summary, unwanted software can cause system infections, financial losses, severe privacy issues, and even result in identity theft. To ensure device and user safety, all suspect applications and browser extensions/plug-ins must be removed immediately upon detection.

CacheImprovmentMicroClickProcesserLogOpticalPartition - are some examples of browser hijackers. They look legitimate and offer various "handy" functionalities. However, these features are seldom operational. This applies to practically all PUAs. The sole purpose of unwanted apps is to generate profit at user expense. Therefore, instead of delivering on any promises, PUAs can run intrusive advert campaigns, hijack browsers, cause redirects, and gather vulnerable data.

How did ExpandedTask install on my computer?

PUAs are distributed through download/installation setups of other programs. This false marketing technique of packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g., ignored terms, used "Easy/Express" settings, etc.) increase the risk of unintentionally allowing bundled content into the system. Intrusive ads spread PUAs as well. Once clicked on, the advertisements can execute scripts to download/install these applications without user consent. Select PUAs have "official" download sites.

How to avoid installation of potentially unwanted applications?

It is recommended to research software prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Since 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 important to read terms, explore possible options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate and harmless; however, they redirect to various questionable (e.g., gambling, pornography, adult-dating, and so forth). 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 detected - immediately removed from it. If your computer is already infected with ExpandedTask, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
