How to uninstall the Mac Cleaner application
Written by Tomas Meskauskas on (updated)
What is Mac Cleaner?
Mac Cleaner is designed to clean, protect and optimize Mac computers by removing junk, duplicate files, and uninstalling unwanted, redundant apps, etc. In fact, this app is distributed using dubious methods. Users often download and install these apps onto their computers inadvertently and, therefore, they are categorized as potentially unwanted applications (PUAs).
Mac Cleaner has features that allow users to scan their Mac computer for large and old files, duplicates, privacy data, and installed programs, and then to remove them. To remove any detected files (or other data), however, users must activate Mac Cleaner by paying for its full version.
I.e., the free version allows scanning of systems, but not to perform any further actions. These PUAs provide fake results and detect fake issues. Apps that perform fake scans do not improve computer performance, fix any issues, remove files, etc.
Their main purpose is to trick users into believing that there are actions that can be taken (in this case, to improve computer performance) using their features so that users pay for activation/registration of their bogus software. It is unknown whether Mac Cleaner performs a fake scan or provides any valid functions, however, there is a strong possibility that this is rogue software.
Note that it is possible that the developers distribute this app with other PUAs. For example, browser hijackers and/or adware-type apps. Browser hijacking programs promote fake search engines by changing certain browser settings. Adware-type apps serve advertisements.
Furthermore, both browser hijackers and adware-type apps can collect browsing-related and other sensitive data. The collected data could be misused to generate revenue. For example, it might be sold to third parties (potentially, cyber criminals). This can cause problems with browsing safety, online privacy, and some users might even become victims of identity theft.
Therefore, remove all PUAs (including Mac Cleaner) from browsers and computers.

Mac Cleaner is identical to MacMaster and similar to many other apps including Mac Optimizer Pro, MacCleanBooster, and Quick Mac Fixer. In most cases, these apps are advertised as tools that clean computers, find and remove malware, fix errors and are useful in other ways.
In fact, they often do not function as advertised. Furthermore, many users download and install these apps inadvertently.
How did potentially unwanted applications install on my computer?
PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".
By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.
When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.
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.

Now open your launchpad and click on the Combo Cleaner icon. Wait until Combo Cleaner updates its virus definition database and click the "Start Combo Scan" button.
Combo Cleaner will scan your Mac for malware infections. If the antivirus scan displays "no threats found" - this means that you can continue with the removal guide; otherwise, it's recommended to remove any found infections before continuing.
After removing files and folders generated by the adware, continue to remove rogue extensions from your Internet browsers.
