Mac Purifier Unwanted Application (Mac)

Also Known As: Mac Purifier potentially unwanted application
Type: Mac Virus
Damage level: Medium

What is Mac Purifier?

Similar to Safe Cleaner for Mac, Mac Clean Pro, and many others, Mac Purifier is a dubious application presented as a great system optimization tool.

Judging on the features offered, Mac Purifier may seem legitimate and useful, however, developers proliferate this app using a deceptive marketing method called "bundling" and, thus, it often infiltrates systems without permission. Therefore, Mac Purifier is categorized as a potentially unwanted application (PUA).

Mac Purifier unwanted application

The main Mac Purifier feature is malware removal. After performing a full system scan, users are presented with a list containing hundreds of viruses/threats that must be eliminated. Yet, only the paid (full) versions are supposedly capable of this. In other words, users must pay to remove the threats.

Note that hundreds of "bundled" fake anti-virus/system optimization tools generate false search results in this way. Therefore, it is currently unknown whether Mac Purifier can actually be trusted - it is not confirmed whether the listed infections actually exist.

There is a strong chance that cyber criminals intentionally attempt to scare unsuspecting users simply to trick them into purchasing the 'full' version. Therefore, we advise you to uninstall this application and certainly not to pay for the full version.

"Bundling" is often used to proliferate several potentially unwanted applications at once, and so Mac Purifier may not be the only PUA that has infiltrated your computer.

In most cases, "bundling" is used to proliferate adware and browser hijackers. These apps deliver intrusive advertisements, cause unwanted redirects, and gather sensitive information, thereby posing a direct threat to your privacy and Internet browsing safety. As well as removing Mac Purifier, you should eliminate other dubious applications/browser plug-ins.

Research shows that there are hundreds of potentially unwanted applications, all of which are virtually identical. These programs deliver fake promises to provide "useful features", however, these false claims are only attempts to give the impression of legitimacy and trick users to install.

Developers release potentially unwanted applications only to generate revenue, and thus most deliver no value for regular users. Bogus apps promote in-app purchases, cause redirects, deliver ads, and record information.

How did potentially unwanted applications install on my computer?

Mac Purifier is free for anyone to download on its official website, however, as mentioned above, it is also proliferated using a deceptive marketing method called "bundling" - stealth installation of third party apps with regular (typically free) software.

Developers do not disclose "bundled" PUA installations properly - they hide them within "Custom/Advanced" settings (or other sections) of the download/installation processes.

In addition, many users rush and skip steps - behavior that often leads to inadvertent installation of apps such as Mac Purifier. In this way, many users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

Select "Custom/Advanced" options and carefully analyze each window of the download/installation dialogs. Opt-out of additionally-included apps and decline offers to download/install them. We recommend that you download programs from official sources only, using direct download links.

Third party downloaders/installers are monetized using the "bundling" method, and thus these tools should not be used. Potentially unwanted applications are often distributed using intrusive advertisements.

Developers invest many resources into intrusive ad design, thereby making them seem legitimate, however, the ads often redirect to dubious websites (gambling, adult dating, pornography, etc.).

If you experience these redirects, eliminate all dubious applications and browser plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
