Remediation Steps:
Isolate the machine from the network immediately. Run a full antivirus scan with updated definitions to remove all components. Investigate for persistence mechanisms (e.g., scheduled tasks, registry keys) and signs of secondary payloads. For maximum security, re-image the machine from a known-good backup and reset all user credentials.
