How to uninstall the PowerMyMac application

What is PowerMyMac?

PowerMyMac is advertised as a tool that optimizes and cleans Mac computers, however, this app is proliferated using dubious methods, which increases the chance that users will download and install it inadvertently. For this reason PowerMyMac is categorized as a potentially unwanted application (PUA).

PowerMyMac allows users to scan their computers for large, old files, duplicate files, and to uninstall unwanted apps, private data, system cache and other items, however, none can be removed with the nonactivated version of the PowerMyMac app. I.e., to use features available in PowerMyMac, users must pay.

Note that apps that are categorized as PUAs often perform fake scans (e.g., detect fake issues) to trick users into paying for their full versions. It is unknown whether PowerMyMac functions as one of these rogue apps, however, there is a strong possibility.

Installers for apps such as PowerMyMac are also used to distribute other PUAs. For example, browser hijackers, adware-type apps. Browser hijackers promote fake search engines by modifying certain browsers settings.

Adware-type apps are designed serve ads that, when clicked, open dubious web pages or even cause unwanted downloads and installations by running certain scripts. Adware-type apps and browser hijackers gather browsing-related information and even private, sensitive data.

The collected data could be sold to third parties (potentially, cyber criminals) or misused in other ways.

Wise Mac Care, PowerSuite and Osx Uninstaller are the names of other similar PUAs. You are advised against trusting apps of this kind, especially if they are not free. They will not fix any detected errors, remove issues, or eliminate malware. You are advised to use only reputable apps.

How did potentially unwanted applications install on my computer?

Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software.

This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.

In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.

Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system. If your computer is already infected with PUAs, we recommend running a scan with one of the Top Antivirus Software to automatically eliminate them.

Scan your Mac with Combo Cleaner:

If you have followed all the steps correctly, your Mac should be clean of infections. To ensure your system is not infected, run a scan with Combo Cleaner Antivirus. Download it HERE.

Now open your launchpad and click on the Combo Cleaner icon. Wait until Combo Cleaner updates its virus definition database and click the "Start Combo Scan" button.

Combo Cleaner will scan your Mac for malware infections. If the antivirus scan displays "no threats found" - this means that you can continue with the removal guide; otherwise, it's recommended to remove any found infections before continuing.

After removing files and folders generated by the adware, continue to remove rogue extensions from your Internet browsers.
