How to remove PowerMyMac from Mac?

What is PowerMyMac?

PowerMyMac is advertised as a tool that is designed to optimize and clean up Mac computers. However, it is known that this app is distributed by using questionable methods which increases a chance that users could download and install this app unknowingly. For this reason PowerMyMac is categorized as potentially unwanted application (PUA).

PowerMyMac unwanted application

PowerMyMac allows users to scan their computers for large, old files, duplicate files, uninstall unwanted apps, private data, system cache and other items. However, none of them can be removed with the nonactivated version of the PowerMyMac app. In other words, in order to be able to use features that are available in PowerMyMac users need to pay for it. It is worthwhile to mention that apps that are categorized as PUAs can be designed to perform fake scans (e.g., detect fake issues) to trick users into paying money for their full version. It is unknown whether PowerMyMac is designed to function as one of these apps, however, there is such a possibility. Also, it is common that installers for apps like PowerMyMac are used to distribute other PUAs, for example, browser hijackers, adware-type apps. Browser hijackers are designed to promote fake search engines (their addresses) by modifying certain browsers settings. Adware-type apps are designed serve various ads that, when clicked, tend to open questionable pages or even cause unwanted downloads, installations by running certain scripts. Quite often both adware-type apps and browser hijackers are designed to function as data collectors that gather browsing-related information, or even sensitive detail. The problem with it is that collected data could be sold to third parties (potentially cyber criminals) or misuse it in other ways.

Wise Mac Care, PowerSuite and Osx Uninstaller are the names of other more or less similar PUAs. It is recommended not to trust apps of this kind, especially if they are not free. Such apps may not fix any detected errors, remove issues, eliminate malware, etc., or be useful in some other way. It is advised to use only reputable apps.

How did potentially unwanted applications install on my computer?

It is common that potentially unwanted applications are distributed by using a deceptive marketing method called "bundling" - by including them in download and/or installation setups of other programs as extra offers. In most cases those offers can be declined in "Custom", "Advanced" other settings of setups, or by unticking certain checkboxes. When users download and/or install programs without doing that, they agree with offers to download/and or install included apps as well. Sometimes unwanted downloads and/or installation can be caused by clicking deceptive ads, however, they cause it only when they click ads that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Neither programs aor files should be downloaded (or installed) from unofficial websites, via third party downloaders, installers, Peer-to-Peer networks (like torrent clients, eMule), etc. They should be downloaded only from reliable, official sites and via direct download links. Download and/or installation setups with settings like "Custom", "Advanced" (or checkboxes) should be always checked for offers to download and/or install additionally included apps. Ads that appear on questionable websites should not be trusted (clicked): they can be designed to open shady websites or cause downloads, installations of some unwanted applications. Suspicious, unwanted extensions, add-ons or plug-ins that are already installed on a browser should be removed from it. The same should be applied to programs of this kind that are 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.
