How to remove Mac Clean Pro from Mac?

What is Mac Clean Pro?

Similar to Advanced Mac Tuneup and Secure Mac Tuneup, Mac Clean Pro is a dubious application that claims to clean and optimize computers. Judging on appearance alone, Mac Clean Pro may seem legitimate and useful, however, this app is categorized as a potentially unwanted application (PUA), since developers proliferate it using a deceptive marketing method called 'bundling'.

Virus removal is one of the main Mac Clean Pro features. After scanning the system, users are presented with many infections that must supposedly be eliminated. The 'free version' of Mac Clean Pro is apparently not able to do this. Therefore, to resolve all issues, users must purchase the 'full version'. Bear in mind, however, that the Mac Clean Pro application is bogus - there is no guarantee that the listed infections actually exist. Furthermore, there are dozens of fake anti-virus/system optimization tools distributed using the 'bundling' method. All claim that system is damaged, but these claims are merely attempts to promote in-app purchases. Again, it is currently unknown whether Mac Clean Pro scan results are trustworthy - there is a high probability that your computer is optimized and virus-free. Therefore, we advise to remove this application and not to pay for the full version. If you are not sure whether your computer is safe, scan the system with a legitimate anti-virus/anti-spyware suite, such as Combo Cleaner Antivirus for macOS. As mentioned, developers promote Mac Clean Pro via the 'bundling' method. In most cases, 'bundling' is used to proliferate several PUAs at once. Therefore, Mac Clean Pro might be one of a number of PUAs that infiltrated your system. 'Bundling' is often used to proliferate adware and browser hijackers that deliver intrusive advertisements, gather sensitive information, and cause unwanted redirects. Therefore, if Mac Clean Pro has infiltrated the system without your consent, also remove other dubious applications/browser plug-ins.

The Internet is full of rogue potentially unwanted applications that claim to be legitimate. By offering 'useful features', these programs often trick users to install, however, since their only purpose is to generate revenue for the developers, many PUAs provide no significant value for regular users. These rogue applications cause unwanted redirects, deliver intrusive advertisements, record personal information, and promote in-app purchases. In doing so, they pose a significant threat to your privacy and browsing safety.

How did potentially unwanted applications install on my computer?

Mac Clean Pro has an official download website, however, remember that developers promote this potentially unwanted applications using the aforementioned 'bundling' method - stealth installation of software with regular (usually free) applications. Developers do not disclose installation of 'bundled' applications properly. They conceal them within various sections (in most cases, 'Custom' or 'Advanced' settings) of the download/installation procedures. In addition, users often rush these procedures and skip steps - behavior that often leads to inadvertent installation of potentially unwanted applications such as Mac Clean Pro.

How to avoid installation of potentially unwanted applications?

Carefully analyze all windows of the download/installation dialogs. Select 'Custom/Advanced' settings, observe each step, and opt-out of all additionally-included applications. We also recommend that you avoid using third party downloaders/installers, since developers monetize them by 'bundling' PUAs. Apps should be downloaded from official sources only, using direct download links. As well as using the 'bundling' method, developers proliferate potentially unwanted applications using intrusive advertisements (which lead to malicious websites and run scripts that download and install PUAs). Most of these ads seem legitimate, but typically lead to dubious websites (pornography, gambling, adult dating, etc.). If you experience these ads, eliminate all dubious applications and browser plug-ins. The main reasons for computer infections are lack of knowledge and careless behavior - the key to safety is caution. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
