How to remove MacKeeper from Mac?

What is MacKeeper?

Developed by Zeobit and then acquired by Kromtech, MacKeeper is a legitimate and useful application for Mac users. It provides functionality that allows users to optimize and increase system performance. Despite this, some MacKeeper affiliates employ dubious/unacceptable measures to proliferate this software. Therefore, it can be classed as potentially unwanted program (PUP).

MacKeeper adware

This application is proliferated in various ways. It has an official download website, which is fine as a legitimate app, however, as mentioned above, some criminals proliferate this program in dubious ways. For example, they develop malicious websites that display fake error messages claiming that the system is corrupted. To resolve these "issues" (that do not exist), users are encouraged to download MacKeeper. The list of dubious sites includes (but is not limited to) Virus Found and We Have Detected A Trojan Virus. Criminals also proliferate this application using intrusive advertisements (pop-ups, banners, etc.) and a deceptive marketing method called "bundling". If you feel that MacKeeper has infiltrated systems without your consent, follow the guide below and remove this application.

The aforementioned methods are also used to proliferate other PUPs that are not legitimate (e.g., adware, browser hijackers, etc.) Most generate intrusive advertisements and record various sensitive data. The ads are delivered using various tools that enable placement of third party graphical content on any site. Therefore, they often conceal underlying website content, thereby diminishing the web browsing experience. Most PUPs are also designed to gather various information that typically includes personal details. Internet Protocol (IP) addresses, Internet service providers (ISPs), geographic locations, URLs visited, pages viewed, queries entered into search engines, keystrokes, and other collected data is later sold to third parties (potentially, cyber criminals). These people generate revenue by misusing private information. Therefore, the presence of information-tracking apps can lead to serious privacy issues or even identity theft. We highly recommend that you remove all dubious applications and browser plug-ins.

All potentially unwanted programs are very similar. By offering a number of features, PUPs such as MyShopcoupon, TURBOMAC, and others, attempt to give the impression of legitimacy, however, their only purpose is to generate revenue for the developers. Only a small percentage give the features promised - most are useless. Rather than (or together with) enabling the functionality promised, potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety.

How did MacKeeper install on my computer?

As mentioned above, MacKeeper is proliferated using intrusive ads, together with the "bundling" method. Intrusive ads redirect users to malicious websites and/or run scripts that download/install PUPs. Therefore, even a single click might result in inadvertent installation of certain applications. "Bundling" is stealth installation of PUPs together with regular software. Developers hide "bundled" apps within "Custom/Advanced" settings (or other sections) of the download/installation processes. Many users rush these procedures and skip steps. In doing so, they expose their systems to risk of various infections. The main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of potentially unwanted applications?

To prevent this situation, pay close attention when browsing the Internet and, especially when downloading/installing software. Bear in mind that criminals invest many resources into developing intrusive ads. They often seem legitimate, but are distinguishable, since most lead to survey, gambling, pornography, and other dubious websites. As mentioned before, intrusive ads are typically delivered by PUPs and, thus, if you encounter them, immediately remove all suspicious applications and browser plug-ins. Select "Custom/Advanced" settings, carefully analyze each window of the download/installation procedures, and opt-out of all additionally-included programs. You are advised to download software from official sources only, using direct download links, since criminals employ third party downloaders/installers to proliferate ("bundle") PUPs. Using a legitimate anti-virus/anti-spyware suite is also paramount. The key to computer safety is caution.
