How to remove Umate Mac Cleaner from Mac computers

What is Umate Mac Cleaner?

Umate Mac Cleaner is untrusted software endorsed as a tool for optimizing the performance of Mac operating systems. This application is supposedly capable of eliminating junk, large and duplicate files, and also removing personal information to prevent privacy leaks. Since most users download/install Umate Mac Cleaner inadvertently, it is classified as a Potentially Unwanted Application (PUA). Often, apps within this classification cannot perform their advertised functionality and might have undisclosed dangerous capabilities.

Products are categorized as PUAs, due to the dubious methods used to proliferate them. Such techniques may be employed for legitimate software, however, they are more commonly used to proliferate rogue applications. Some PUAs (e.g. fake anti-virus tools) require activation to operate as advertised, but even after the activation keys are purchased, the apps remain nonoperational. Furthermore, this unwanted software can have hidden and harmful functions. PUAs can force-open various dubious and malicious websites. Adware-types run intrusive advertisement campaigns. The delivered ads (pop-ups, banners, surveys, full-page, etc.) reduce browsing speed and limit website visibility. In addition, once clicked, intrusive ads can redirect to dangerous sites and some can even stealthily download/install software. Other PUAs called browser hijackers make modifications to browser settings and restrict/deny access to them to promote fake search engines. Therefore, with a browser hijacker installed, each new browser tab/window opened and search query typed into the URL bar redirects to the promoted address. Fake search engines are seldom capable of providing search results, and so they tend to redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other legitimate search engines. Furthermore, most PUAs (regardless of type) have data tracking capabilities. They can monitor browsing activity (browsing and search engine histories) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is then monetized by sharing with and/or selling to third parties (potentially, cyber criminals). In summary, the presence of unwanted apps on devices can result in system infections, serious privacy issues, financial loss and even identity theft. To ensure device integrity and user safety, all suspicious applications and browser extensions/plug-ins must be removed without delay.

Mac CleanerMac Optimizer ProMacCleanBooster, and MacMaster are some examples of applications similar to Umate Mac Cleaner. PUAs may seem legitimate and offer a broad range of "useful" functionality, however, despite how good the features promised may sound, they are rarely operational. The only purpose of this unwanted software is to generate revenue for the developers. Rather than delivering any real value, PUAs can force-open untrusted and malicious web pages, run intrusive ad campaigns, hijack browsers, collect sensitive and personally identifiable information.

How did potentially unwanted applications install on my computer?

Some PUAs (including Umate Mac Cleaner) have "official" promotional sites, from which they can be downloaded and/or purchased. Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default. In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided. When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
