The parent process also matches the expected behavior of Edge.\n\n---\n\n### \ud83e\udd16 deepseek-r1:16b Analysis (Secondary + RAG)\n**Verdict:** false_positive | **Confidence:** 0.9\nThe detection event involves the Microsoft Edge browser process starting a utility service.

The file path is within the expected Program Files directory, and the file is signed by Microsoft, indicating it is not malicious.\n\n**IOC Analysis:** FILE_PATH is located in C:\\Program Files (x86)\\Microsoft\\Edge, which is a known legitimate software directory.
