Remediation Steps:
Immediately isolate the infected host and perform a full system scan with updated antivirus/EDR software to remove all detected malicious files and associated artifacts. Review system logs for evidence of persistence mechanisms (e.g., scheduled tasks, modified registry keys) and investigate for lateral movement or data exfiltration.
