MacOS.iDoctor.H is a Potentially Unwanted Application (PUA) detection for macOS that typically spreads as fake optimization software. Such rogue apps are very common as they are an easy way of infecting computers with various dangerous malware threats. Mac users usually download and install iDoctor.H from untrusted websites, faux landing pages and portals, online forums, or social media posts. Another standard distribution method of PUAs is called 'bundling.' When that method is used, the undesired apps and tools are delivered through popular freeware installers. Malware developers also spread their creations through phishing email campaigns where the malicious files are hidden within attached documents.
Once MacOS.iDoctor.H is installed on your Mac computer, the scope of the damage it can cause seems broad. Initially, the app may pretend to be fulfilling its purpose by running some cleaning/optimization processes and scanning certain files; however, in the end, it will most likely display a message that prompts you to purchase the full version to get the problems solved. More likely, though, the detected issues do not even exist, and even if they do, macOS itself already has all the utilities to deal with them.
As this app may exhibit some typical characteristics of an adware threat, affected users can expect that it will deliver unsolicited advertisements, suspicious pop-ups, and other intrusive messages and alerts. Though, in the background, much more destructive processes may be running. MacOS.iDoctor.H can collect personal user data, system information, and other valuable details. As a result, users may suffer identity abuse, financial losses, data loss, as well as PC performance issues. Some PUPs also can deliver additional malware threats, like Trojans, RATs, or even Ransomware.
