How to remove MacEnizer from Mac?

What is MacEnizer?

MacEnizer is categorized as a potentially unwanted application (PUA), since developers promote it using dubious, deceptive methods. Most people download and install PUAs unintentionally, however, MacEnizer is advertised as a system optimizer, a tool that supposedly cleans and maintains Mac computers.

MacEnizer unwanted application

MacEnizer includes features that supposedly allow users to manage cache, trash, logs, startup items, uninstall apps, clean memory, history, etc., however, these functions cannot be performed with the free/trial version. To use all MacEnizer features, people must purchase/activate it. Despite these demands, do not pay for apps that are classified as PUAs. They often provide false results to trick people into believing that their computers can run faster, and without errors if the 'full version' of this app is purchased. It is not known for certain whether MacEnizer is one of these rogue applications, however, there is a strong possibility. Furthermore, PUAs are often distributed with other unwanted apps such as browser hijackers, adware, and so on. Apps that hijack browsers usually change browser settings to promote a dubious web address (often a fake search engine) and gather information relating to browsing habits. Examples of data collected by PUAs include users' IP addresses, entered search queries, addresses of opened websites, and geolocations. Some are also designed to record personal details. Developers of PUAs share the data with other parties who misuse it to generate revenue. Some these third parties might include cyber criminals. Adware is a type of software that, once installed, starts to feed users with unwanted, intrusive ads. If clicked, these open dubious or even malicious web pages or start the download/installation processes of various unwanted apps. If there are any apps of this type installed on your browser or operating system, remove them immediately.

MacEnizer is not the only app categorized as PUA. Other examples are Mac Clean Pro, Mac Fixer Pro, and Advanced Mac Booster. Typically, developers advertise them as legitimate, useful programs that supposedly fix errors, uninstall unwanted software, clean computers, and so on. In many cases, however, these apps do not function as promised and are redundant. Most are not free and people are often tricked into purchasing them.

How did potentially unwanted applications install on my computer?

MacEnizer can be downloaded from its download website, however, most people download and install PUAs unintentionally. To trick people into these unwanted downloads/installations, developers use a deceptive marketing method called "bundling". They include PUAs into the set-ups of other programs and hide related information in "Advanced", "Custom", and other settings. Furthermore, many people leave these settings unchecked and unchanged, thereby granting permission for PUAs to be downloaded and installed with other regular software. In some cases, unintentional downloads/installations are caused through deceptive ads. If clicked, these can run scripts that download and install unwanted, potentially malicious apps.

How to avoid installation of potentially unwanted applications

To avoid unwanted installations/downloads, check all settings available in the set-ups of software, especially if the software is free. Dismiss offers to download/install additional apps before completing the download/installation process. Avoid using third party software downloaders, installers, unofficial pages, Peer-to-Peer networks such as torrent clients, eMule, and other such tools. The best way to download programs and files is to use official websites and direct links. Do not trust intrusive ads, especially those displayed on dubious web pages. Once clicked, they can redirect users to untrustworthy websites or cause unwanted downloads and installations. If your browser causes redirects to dubious pages or shows ads, remove all unknown/suspicious extensions, plug-ins, or add-ons from your browser, and programs from the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
