How to remove MacPerformance from Mac?

What is MacPerformance?

MacPerformance is an adware program that causes various intrusive pop-up ads. Developers claim that this app enhances Mac computer performance, however, MacPerformance is part of the OSX Pirrit adware family and categorized as a potentially unwanted, malicious application. Therefore, many users install MacPerformance unintentionally. As well as distributing intrusive advertisements, MacPerformance records information relating to browsing activity.

MacPerformance adware

Once installed, MacPerformance requests permission to access and control the Safari browser. Once permission is granted, this app continuously collects browsing-related data, including IP addresses, search queries, URLs of visited websites, geo-locations, and so on. Collected data might also contain personal/sensitive details. These unwanted apps usually share this information with third parties (potentially, cyber criminals) who misuse it to generate revenue. Granting permission for MacPerformance to control Safari allows it to display various pop-up ads, such as Your MacOS 10.14 Mojave Is Infected With 3 Viruses!, Your Computer Was Locked, Mac OS Support Alert, and so on. Pop-up ads of this type are designed to trick people into purchasing unnecessary software or 'technical support' by indicating that the Mac is infected with viruses or there are other problems that need to be fixed immediately. MacPerformance adware might also display other ads (coupons, banners, surveys, etc.) that, if clicked, redirect users to untrustworthy/deceptive websites. Some of these ads can even run scripts designed to download/install unwanted apps. They are often displayed using tools that enable placement of third party graphical content on any site, and conceal underlying content. If MacPerformance is installed on your Mac, we strongly recommend that you uninstall it immediately. You can find MacPerformance files in this directory: "/Users/user1/Library/UpdateMac/MacPerformance/".

Many adware-type apps are promoted as 'useful tools'. In this case, developers claim that they are capable of enhancing Mac performance, however, apps of this type provide none of the functionality promised and are designed only to generate revenue for the developers (by causing unwanted redirects, feeding users with ads, and gathering data). Some examples of other adware-type apps are Adblocking Addon, EasyDirections, and RinoReader.

How did MacPerformance install on my computer?

Some potentially unwanted apps can be downloaded from their official websites, however, most users install them unintentionally - they are tricked through intrusive ads or when software developers use the "bundling" method. MacPerformance is mostly bundled with fake Flash Player installers. Bundling is a deceptive marketing method used to trick users into installing (or downloading) unwanted apps together with other software. Generally, developers do not disclose information about the bundling of these apps with install/download set-ups. They hide them in "Custom", "Advanced" and other similar settings. Despite this, inadvertent installations and downloads happen when users do not check installation/download settings or skip steps.

How to avoid installation of potentially unwanted applications?

Download software using official, trustworthy websites and direct links. Do not use third party tools such as software installers, downloaders, etc. Check "Custom", "Advanced", and other options/settings when installing or downloading software. Deselect any additional (potentially unwanted) applications offered, and only then finish the installation/download. Many intrusive ads redirect users to deceptive, untrustworthy or even malicious websites, such as adult dating, gambling, pornography, and so on. If you encounter these ads, check installed programs on your computer, and extensions, add-ons, and plugins installed on your browser. Remove all unwanted/unknown entries immediately. If your computer is already infected with MacPerformance, we recommend running a scan with Spyhunter for Windows to automatically eliminate this adware.
