How to remove iMacCleaner from Mac computers

What is iMacCleaner?

iMacCleaner is advertised as a software which improves computer performance by cleaning unwanted files and the browser cache, and uninstalling unwanted software. In fact, this app is categorized as a potentially unwanted application (PUA) due to the method that developers use to distribute it: they include iMacCleaner as an additional offer into the set-ups of other programs. Commonly, people download and install these apps inadvertently.

iMacCleaner unwanted application

iMacCleaner allows users to scan computers for unwanted programs, unnecessary files and other entries/items, however, they cannot be cleaned/removed without upgrading iMacCleaner to the Pro version. I.e., to clean their computers with iMacCleaner, users must pay for the software. These apps are categorized as PUAs, since they do not fix any errors, remove unwanted items, etc., even if users pay for activation/registration. The apps simply display fake detections to trick people into believing that they can improve computer performance with the paid version. It is unknown whether iMacCleaner is a deceptive application, however, many PUAs are within this category. PUAs are often distributed with other apps of this kind including, for example, adware and browser hijackers. Adware serves various intrusive ads (e.g., banners, pop-up ads, coupons, surveys). When clicked, these can open untrusted websites or execute scripts designed to download and install unwanted software. Browser hijackers force users to visit a specific address (of a fake search engine) when they open a browser, new tab, or enter search queries into the URL bar. They achieve this by changing browser settings such as the address of the homepage, default search engine and new tab. Adware-type apps and browser hijackers often collect details such as geolocations, entered search queries, addresses of visited websites, IP addresses and other browsing data. In some cases, PUAs target personal, sensitive details. The information might be misused to generate revenue by selling it to third parties (potentially, cyber criminals), or in other ways. Therefore, do not trust any PUAs (including iMacCleaner) and uninstall them immediately.

Some more examples of apps similar to iMacCleaner include Easy Mac Care, MacReviver and MacRepair. These apps supposedly optimize computer performance by fixing errors, cleaning junk files, uninstalling unwanted software, and in other ways. In fact, PUAs are useless and designed to extort money from unsuspecting users. Therefore, do not pay for activation/full versions of dubious apps.

How did potentially unwanted applications install on my computer?

In some cases, unwanted downloads and installations can be caused via deceptive ads that execute certain scripts, however, PUAs are more commonly downloaded and installed with other (usually free) software. I.e., when they are included into the set-ups of other programs as 'additional offers'. Typically, such offers are mentioned in (and can be declined through) "Custom", "Advanced" and other similar settings. Many users fail to check and change the aforementioned settings, thereby allowing PUAs to infiltrate. This distribution method is called "bundling".

How to avoid installation of potentially unwanted applications

Do not download or install software/files through third party downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial pages and so on. Use official pages and direct download links only. Check "Custom", "Advanced" and other settings before completing the process. Decline any offers to download or install additional, unwanted software. Do not click intrusive ads, since they can open untrusted, potentially malicious websites. In some cases, they can download and install PUAs. Remove any unwanted, suspicious plug-ins, extensions and add-ons that are installed on the browser, and software that is installed on 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.
