How to remove iMacCleaner from Mac?

What is iMacCleaner?

iMacCleaner is advertised as a software which improves computer performance by cleaning unwanted files, browser cache and uninstalling unwanted software. However, this app is categorized as a potentially unwanted application (PUA) because of the method that developers use to distribute it: they include iMacCleaner as an additional offer in setups of other programs. It is common that users download and install such apps unknowingly, unintentionally.

iMacCleaner unwanted application

iMacCleaner allows users to scan computers for unwanted programs, unnecessary files and some other entries, items. Although, they cannot be cleaned/removed without having to upgrading iMacCleaner to Pro version. In other words, to be able to clean computers with iMacCleaner users have to pay for it. The problem with it is that apps that are categorized as PUAs often do not fix any errors, remove unwanted items, etc., even if users pay for their activation/registration. It i common that such apps display fake detections to trick users into believing that they could improve computer performance by using their paid version. It is unknown whether iMacCleaner is a deceptive application, although, quite many PUAs are. Another issue with PUAs is that they often are distributed together with some other app of this kind, for example, some adware or browser hijackers. Adware is a type of software that serves various intrusive ads (e.g., banners, pop-up ads, coupons, surveys). When clicked, those ads often either open some untrustworthy websites or execute scripts designed to download and/or install unwanted software. Browser hijackers are designed to force users to visit certain address (some fake search engine) wen they open a browser, new tab and enter search queries into URL bar by changing browser's settings such as address of a homepage, default search engine and new tab. Both adware-type apps and browser hijackers can be designed to collect details like geolocations, entered search queries, addresses of visited websites, IP addresses and other browsing data as well. In some cases apps of this type target personal (sensitive) details. There is always a possibility that recorded information could be misused to generate revenue by selling it to third parties (potentially cyber criminals) or in some other ways. Therefore, it is recommended not to trust any PUAs (including iMacCleaner) and uninstall any installed ones as soon as possible.

Some more examples of apps like iMacCleaner are Easy Mac Care, MacReviver and MacRepair. It is common that such apps supposed to optimize computers (improve their performance) by fixing errors, cleaning junk files, uninstalling unwanted software and/or in some other ways. Although, there are apps of this type that are useless and designed to extract money from users. Therefore, it is strongly recommended not to pay money for questionable apps (their activation, full version, etc.).

How did potentially unwanted applications install on my computer?

In some cases unwanted downloads, installations can be caused via deceptive ads that are designed to execute certain scripts. Nevertheless, more often PUAs get downloaded and/or installed together with some other, usually free software. To be more precise, when they are included in setups of other programs as additional offers. Typically, such offers are mentioned in and can be declined through "Custom", "Advanced" and other similar settings of setups. Users agree with offers to download and/or install unwanted apps when they download and install programs that have them included in their setups without changing the aforementioned settings. This distribution method is called "bundling".

How to avoid installation of potentially unwanted applications?

It is not recommended to download and install software (or files) through third party downloaders, installers, Peer-to-Peer networks like torrent clients, eMule, unofficial pages and so on. Only official pages and direct download can be really trusted. Furthermore, it is important to check "Custom", "Advanced" and other settings of setups before completing ownloadsand/or installations. Those settings often mention offers to download and/or install additional, unwanted software. Intrusive ads, when clicked, tend to open various untrustworthy, potentially malicious websites. In some cases they can be designed to download and/or install some PUA. Therefore, it is not recommended to click such ads as well. Any unwanted, suspicious plug-ins, extensions and/or add-ons that are installed on browser and software that is installed on the operating system should be uninstalled. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
