How to remove DiscoveryEngine from Mac?

What is DiscoveryEngine?

DiscoveryEngine is a rogue application, promoted as a tool capable of improving the browsing experience. It can supposedly provide fast searches, accurate search results, etc. Instead, it acts as adware. In other words, it runs intrusive advertisement campaigns - delivers undesirable and possibly dangerous ads. It is not uncommon for adware to also have data tracking abilities, which they use to gather intel on users' browsing activity. Furthermore, DiscoveryEngine is classified as a PUA (Potentially Unwanted Application), due to its dubious proliferation methods.

DiscoveryEngine adware

Adware-type applications display a wide variety of intrusive advertisements, such as pop-ups, banners, surveys, coupons and so on. These adverts severely diminish browsing quality, by limiting browsing speed and site visibility (i.e. overlay page content). However, they are more than just a mere nuisance, they are deemed to be a threat to device and user safety as well. When they are clicked, they redirect to various sale-oriented, untrustworthy, compromised, deceptive/scam and malicious websites. Additionally, some of these ads can execute scripts, designed to download/install undesirable content. An example of such are PUAs. Aside from running advertisement campaigns, unwanted apps can also generate redirects to likewise harmful webpages. Other types can make unauthorized changes to browsers (hijack them) and limit/deny access to their settings. Most PUAs possess data tracking abilities, which they employ to monitor users' browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather their personal information (IP addresses, geolocations and real-life personal details). This private data can then be shared with third parties (potentially, cyber criminals), intent on misusing it for financial gain. Therefore, applications under this classification can cause browser/system infiltrations and infections, as well as lead to serious privacy issues, financial losses, even identity theft. It is recommended to uninstall DiscoveryEngine without delay. To ensure device integrity and user safety - all dubious apps and browser extensions/plug-ins must be removed immediately upon detection.

Most adware shares certain similarities in-between, in fact this can be attributed to all PUAs. LogicalSearchNeedWebSearchMightyBrowser are a few examples applications similar to DiscoveryEngine. They appear legitimate and entice users into downloading/installing them with offers of "useful" and "beneficial" functions. However, these features are rarely operational, even if they do work - then not as advertised. The only purpose of unwanted apps is to generate revenue for their developers, they are not designed with users in mind and have no genuine value to them. Instead of delivering on any promises, PUAs run intrusive ad campaigns, hijack browsers, cause redirects to untrustworthy/malicious sites and record sensitive data.

How did DiscoveryEngine install on my computer?

Typically, PUAs infiltrate devices through download/installation setups of other products. This deceptive marketing technique of packing regular software with unwanted or malicious content is called "bundling". By rushing through the download/installation processes (e.g. by ignoring or skimming terms, skipping steps and sections, using pre-set options, etc.) - users risk inadvertently allowing bundled applications onto systems. Select PUAs have "official" webpages, from which they can often be downloaded for "free". Intrusive adverts can stealthily download/install these apps, when they are clicked.

How to avoid installation of potentially unwanted applications?

It is recommended to research content to verify its legitimacy, before downloading/installing it. All downloads should be done only from official and verified sources. Download channels like Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites and other third party downloaders - are considered to be untrustworthy. Such sources are advised against use, as they can offer deceptive and bundled software. Download and installation processes should be treated with care. That includes reading terms, exploring all possible options, using the "Custom/Advanced" settings and declining to download/install additional apps, tools, functions, etc. Intrusive ads usually look ordinary and harmless, however they redirect to various dubious pages (e.g. gambling, pornography, adult-dating and others). Should users encounter advertisements/redirects of this nature, they are strongly advised to check the system and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with DiscoveryEngine, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
