How to remove LeadingServiceSearch adware from Mac?

What is LeadingServiceSearch?

LeadingServiceSearch is a piece of rogue software, classified as adware. It also has browser hijacker traits. Following successful installation, this application runs intrusive advertisement campaigns, makes changes to browser settings and promotes fake search engines. Additionally, most adware-types and browser hijackers have data tracking abilities, which are used to record and collect browsing-related information. Since most users download/install LeadingServiceSearch unintentionally, it is considered to be a PUA (Potentially Unwanted Application). One of the dubious techniques used to distribute this app is via fake Adobe Flash Player updates. Users should note that illegitimate software updaters/installers proliferate not only PUAs but trojans, ransomware, and other malware as well.

LeadingServiceSearch adware proliferated via fake Flash Player updater/installer

Adware delivers pop-ups, banners, coupons, surveys and other intrusive advertisements. These ads seriously diminish the browsing experience, as they overlay page content and slow down the browsing speed. When clicked on, intrusive adverts redirect to various unreliable/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: every new browser tab/window opened and every single search query typed into the URL bar - redirect to the address of the promoted illegitimate search engine. These fake web searchers have no real value to users, since they are typically unable to provide search results. Therefore, the promoted search engines tend to redirect to Google, Yahoo, Bing and other legitimate ones. Furthermore, browser hijackers can restrict/deny access to the browser's settings and/or undo any permitted changes made. Most PUAs (adware and browser hijacker included) can track data. They can monitor browsing activity (visited URLs, viewed pages, searched queries, etc.) and gather personal information inferred from it (IP addresses, geolocations and other details). What is more, the collected data is usually shared with and/or sold to third parties (potentially, cyber criminals). To summarize, presence of unwanted apps on devices can result in 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 immediately upon detection.

ExploreParameterGeneralBoardSearchProgramInitiator and DefaultAnalog are some examples of other adware-type apps. They appear legitimate and offer a wide variety of "useful" functionalities. However, the advertised features are seldom operational. In fact, this applies to practically all PUAs. The only purpose of unwanted software is to generate profit for the developers; hence, functionality and user safety are irrelevant. PUAs are designed to deliver intrusive ad campaigns, modify browsers, cause redirects and collect private data.

How did LeadingServiceSearch install on my computer?

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

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. All downloads must be done from official and verified sources. Untrustworthy channels, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is important to read terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive adverts usually appear ordinary and harmless, however they redirect to highly suspicious sites (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with such advertisements and/or redirects, the system must be inspected and all dubious applications and browser extensions/plug-ins - removed without delay. If your computer is already infected with LeadingServiceSearch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
