No suspicious activity was observed.\n\n---\n\n### \ud83e\udd16 deepseek-r1:16b Analysis (Secondary + RAG)\n**Verdict:** false_positive | **Confidence:** 0.9\nThe detection event involves msedge.exe, a legitimate Microsoft Edge process, running under a user account. The file is signed by Microsoft, and the process path is within the expected Program Files directory. The command line arguments appear typical for Edge\u0027s background services. Historical data shows similar events being marked as false positives, and no malicious activity was detected in the process tree.\n\n**IOC Analysis:** The FILE_PATH is located in C:\\Program Files (x86)\\Microsoft\\Edge, which is a known legitimate software location. The file is signed (FILE_IS_SIGNED=1), and the hash matches a known Microsoft-signed binary. The process is spawned from another Edge-related process (PID 31888), which is also signed and legitimate.\n\n---\n\n### \ud83e\udd16 gemma3:4b Analysis (Secondary)\nFailed or timed out.",
