How to remove LeadingAdviseSearch adware from Mac?

What is LeadingAdviseSearch?

LeadingAdviseSearch is a rogue application, categorized as adware that has browser hijacker qualities. Following successful installation, it runs intrusive advertisement campaigns and modifies browsers. This app does the latter in order to promote fake search engines. Additionally, most adware-types and browser hijackers spy on users' browsing activity and it is highly likely that LeadingAdviseSearch does so as well. Due to the dubious methods used to distribute this adware, it is deemed to be a PUA (Potentially Unwanted Application). One of LeadingAdviseSearch's proliferation techniques is via fake Adobe Flash Player updates. It is noteworthy that aside from PUAs, illegitimate software installers/updaters also spread trojans, ransomware and other malware.

LeadingAdviseSearch adware distributed via fake Flash Player updater/installer

Adware operates by delivering pop-ups, banners, coupons, surveys and other intrusive adverts. These ads slow down the browsing speed and limit website visibility (by overlaying page content). Furthermore, once clicked on, the ads redirect to various questionable and malicious sites. Some intrusive advertisements can be triggered (by being clicked) to execute scripts, designed to stealthily download/install software (e.g. PUAs). Browser hijackers reassign browsers' default search engine, homepage and new tab/window URLs - to the addresses of illegitimate web searchers. Hence, with such a piece of software infiltrated: every new browser tab/widow opened and every single search query typed into the URL bar - redirect to the promoted address. Fake search engines are seldom capable of generating search results, so they tend to redirect (or cause redirection chains leading) to Google, Yahoo, Bing and other legitimate ones. Recovering a hijacked browser is impossible without removing the software affecting it. Since browser hijacker can restrict/deny access to the browser's settings and/or automatically undo any permitted changes made. As mentioned in the introduction, most PUAs (adware and browser hijackers included) have data tracking abilities. They can record browsing activity (URLs visited, webpages viewed, search queries, etc.) and gather personal information extracted from it (IP addresses, geolocations and other sensitive details). The collected data is usually shared with and/or sold to third parties (potentially, cyber criminals), similarly seeking to misuse it for profit. In summary, presence of unwanted apps on devices can lead to system infections, financial losses, severe privacy issues and even identity theft. To protect device and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

RequestTopOdysseusLookupSearchRange are some examples of other adware-type apps. They typically appear ordinary and harmless. Users are enticed into download/installation with a wide variety of "useful" features. However, the promised functionalities rarely work. In fact, this is true of nearly all PUAs. The only goal of these applications is to generate revenue for the developers; therefore, functionality and user safety are irrelevant. PUAs are designed to deliver intrusive ad campaigns, hijack browsers, cause redirects and track private information.

How did LeadingAdviseSearch install on my computer?

PUAs are distributed through download/installation setups of other products. This false marketing tactic of packing regular software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps, using presets, etc.) - users risk unintentionally allowing bundled content into their devices. Select PUAs have "official" download websites. Intrusive advertisements proliferate these applications as well. Upon being clicked, they can execute scripts to download/install PUAs without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to always research software prior to download/installation. All downloads must be done from official and verified sources. Untrustworthy channels, like: unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is advised to read terms, study all possible options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tool, features, and so on. Intrusive adverts appear legitimate, however they redirect to unreliable and dubious webpages (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with ads/redirects of this kind, users must check the system and immediately remove all suspect applications and/or browser extensions/plug-ins from it. If your computer is already infected with LeadingAdviseSearch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
