Remediation Steps:
Immediately isolate the infected system from the network. Remove the detected malicious files and perform a full, deep scan with updated antivirus software. Investigate for persistence mechanisms (e.g., scheduled tasks, registry modifications) and signs of compromise such as C2 communication, data exfiltration, or lateral movement. Apply all pending security patches and reinforce endpoint security configurations.
