Is MacKeeper considered a virus or malicious software?

MacKeeper is often perceived with skepticism and has controversial reputation, but it is not classified as a virus or traditional malicious software. MacKeeper is a utility software suite for macOS that provides cleaning, security, and optimization tools. Over the years, it has faced criticism for its aggressive advertising tactics, difficult uninstallation process, and claims of exaggerated benefits. Some users have reported it behaving in a potentially unwanted manner, associating it with performance issues or intrusive pop-ups. Nonetheless, it is a legitimate software product developed by Clario Tech Limited, previously known as Kromtech Alliance. The negative perception is primarily due to user experience concerns and marketing practices rather than an intent to harm computers or users' data.
