Remove unwanted applications injected by the maccleaner.pkg file
Written by Tomas Meskauskas on (updated)
What is maccleaner.pkg?
The maccleaner.pkg file is used to install unwanted software onto MacOS. Examples of applications that might be installed through maccleaner.pkg are Smart Mac Booster, Advanced Mac Cleaner, Mac Cleanup Pro, MacKeeper, Mac Auto Fixer, and Advanced Mac Tuneup.
All of these apps are categorized as potentially unwanted applications (PUAs), since they are advertised on deceptive websites, distributed through fake Flash Player updaters, and so on. If the maccleaner.pkg software package file appears in the Downloads folder (or others), we strongly recommend that you do not open or execute it.
Unwanted apps are promoted with their associated installation files (including maccleaner.pkg) by advertising them on deceptive websites. For example, when opened, scam web pages display fake virus alerts.
They run fake virus scans and trick people into believing that the operating system/computer is infected with a virus and that it can be removed with a certain program (such as Advanced Mac Cleaner, Mac Cleanup Pro, and so on). Websites of this type and software advertised on them should never be trusted (do not download or install).
The maccleaner.pkg file can also be distributed through fake Flash Player updaters. These do not update software, but simply download and install unwanted software.
The maccleaner.pkg file might be disguised as an installation file of an updates package for Flash Player (or other software), however, when opened, it will install one of the aforementioned (or other) unwanted applications. In any case, if downloaded from a dubious channel, the maccleaner.pkg file should never be opened.
The best option is to delete this file and avoid downloading files of this kind in the future. Deceptive (scam) pages are used to promote unwanted software or fake updaters by displaying fake notifications about viruses, outdated software, and so on. These sites are usually opened by PUAs already installed on the system.
Apps of this type open dubious pages, display unwanted ads, and gather data such as IP addresses, URLs of opened pages, entered search queries, geolocations, and other information relating to users' browsing habits. Developers share this data with other people (potentially cyber criminals) who misuse it to generate revenue.
Furthermore, these apps display intrusive ads that, if clicked, open potentially malicious pages or download/install potentially malicious apps. Examples of ads displayed by PUAs include coupons, banners, surveys, pop-ups, etc.

The maccleaner.pkg file is used to install apps that are advertised as useful and legitimate, however, files and programs distributed through deceptive pages (or using other dubious methods) cannot be trusted. Some examples of scam pages that advertise unwanted software through files such as maccleaner.pkg include Checkingforward, Fastsearchday, and Falseortruerdr.
How did potentially unwanted applications install on my computer?
Most users install unwanted apps through dubious, deceptive ads that are capable of running certain scripts or when developers use a deceptive marketing method called "bundling". In any case, people install them inadvertently/unintentionally.
When developers distribute unwanted apps through download or installation set-ups of other software, they hide related information in "Custom", "Advanced", and other similar parts of the set-ups. Unfortunately, many people leave these settings unchanged or even unchecked, thereby agreeing by default to download or install unwanted software included into the setup.
How to avoid installation of potentially unwanted applications?
Download software from official and trustworthy websites and do not use third party installers, downloaders, Peer-to-Peer networks, and so on. Install and download software properly: check "Custom", "Advanced" and other settings of any setup and dismiss offers to download or install additional apps.
Intrusive ads often redirect users to untrustworthy, deceptive websites (especially when displayed on dubious pages). Typically, these ads are shown on pages relating to gambling, adult dating, pornography, and so on. Another reason not to click them is the possibility of unwanted downloads/installations.
Some ads can run scripts that will download and install unwanted software. If the browser opens dubious pages and/or shows unwanted ads, remove all suspicious and unwanted extensions, add-ons, and plug-ins immediately. The same applies to apps installed on the MacOS system.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
