AdLoad variants, MinimalEnergy included, have been plaguing Mac users for a few years. If your system has been affected by an AdLoad variant, we would advise you to check it for related unwanted programs. Instructions to do so are available at the end of this article.

MinimalEnergy Mac Adware – How Did It Get Installed on My Mac?
Adware such as MinimalEnergy generally relies on several distribution techniques. A widely deployed method is software bundling.
Bundling can be described as a form of aggressive advertising used by many programs and software download websites, both legitimate and shady. While many of the bundled programs are generally legitimate, this is one of the main ways potentially unwanted programs such browser hijackers and adware rely on to spread among computer users.
The purpose of bundling is quick monetization. Commonly used software may deliver unwanted apps such as MinimalEnergy. This includes media players, file converters, weather toolbars, online streaming apps, etc.
The installers of these programs often present optional offers or free extras. At the same time, they are not designed to appropriately disclose information about added apps. That’s how users fail to notice their presence during the installation of whatever software they wanted to download.
Other scenarios include users interacting with suspicious pages (torrenting and online streaming websites, adult pages, free online games, etc.). On these pages, users may click on suspicious links, banners, and offers. The result may be an unnoticed download and install of a potentially unwanted program.
A very wide-spread propagation is using a fake Flash Player update. Your browser may generate a fake error message, claiming that “Adobe Flash Player Is Out of Date”. Interacting with the message, like clicking on the download button it provides, will surely install an adware on your Mac.
N.B. Once started on your Mac, such a program could access all installed browsers’ settings to apply significant changes. One of these changes often affects the default search engine in your preferred web browser. If your default search engine is altered without your consent, then don’t waste time but go check your macOS security. This problem is a definite sign that a suspicious piece of software has sneaked into your system.
Furthermore, as long as files associated with the MinimalEnergy adware are running on your Mac, you may be a victim of unsolicited data collection.
By activating different tracking technologies like cookies, web beacons, javascript, or even Trojans, the ad-supported application may become able to obtain a long list of sensitive details, including:
- Visited URLs and websites
- Browser’s home page
- Search queries
- Search queries on the visited web pages
- Type of used browser
- Operating system type
- Internet protocol (IP) address
- Geographic location
- The domain name of the current Internet service provider (ISP)
- Banking credentials
- Entered keystrokes
Shady adware developers may use your data records in targeted advertising campaigns. Once the data is available on their servers, it can be used for the identification of your online interests. Ads delivered by undesired apps may target your interests. At worst, data records will be released on dark web markets for additional revenue.
