Understanding Microsoft Malicious Software Removal Tool for Apple Installation

The Microsoft Malicious Software Removal Tool (MSRT) is designed to detect and remove malicious software from Apple devices. However, the tool itself does not install on Macs by default. Instead, it relies on CoreServicesUIAgent to call XprotectService.xpc, a component of XProtectFramework located at /System/Library/PrivateFrameworks/. This framework plays a crucial role in protecting Apple devices from malware.

When a new process is started with launchd (typically when an app is launched by double-clicking the icon or through Terminal), LaunchServices sends an xpc message to CoreServicesUIAgent. The latter handles the UI aspects of application loading and ensures that only authorized apps are executed on the device. This process takes place in real-time, allowing for swift detection and removal of malicious software.

XProtect, a signature-based malware detection solution available on MacOS, scans for known malicious content whenever an app or command tool is executed. In recent versions of MacOS, XProtect also checks the executable code of every app and command tool when it's run, regardless of whether the quarantine flag is set. This enhanced feature enables more effective protection against malware attacks.

The main XProtect-related data is stored in a loadable bundle located at /Library/Apple/System/Library/CoreServices/XProtect.bundle. Whenever an app or command tool is launched, XProtect checks for known malicious content by comparing the executable code with its signature database. If a match is found, the system takes appropriate action to remove the malware and prevent further harm.

In summary, Microsoft Malicious Software Removal Tool relies on CoreServicesUIAgent and XprotectService.xpc to detect and remove malicious software from Apple devices. By leveraging XProtect's signature-based detection capabilities and real-time scanning features, the tool provides robust protection against malware threats.
