Is MacKeeper considered malware?

MacKeeper is often categorized as potentially unwanted software by users and experts in the cybersecurity community. While MacKeeper is marketed as a utility to optimize and secure Mac computers, its aggressive advertising tactics, bundled installation with other applications, and difficulties in uninstalling have led to it being mistrusted. Additionally, some users report that it exaggerates system issues to encourage the purchase of its full version. However, classifying it strictly as malware would not be accurate since it does not deliberately perform malicious activities like spreading viruses or stealing personal information. It does contain functionalities designed for cleaning and security purposes, but the implementation and user experience have prompted skepticism about its value and legitimacy.
