What is sgav-svc.exe?
sgav-svc.exe is the main Windows service for SGAV SecurityGuard antivirus. It provides real-time protection, scanning, updates, and coordination with the user interface. It runs as a Windows service and can spawn child processes for on-demand scanning and background tasks.
This service handles real-time protection, scheduled scans, and cloud/definition updates. It operates in isolation from user processes to minimize impact on system performance while maintaining defense against threats.
Quick Fact: SGAV antivirus services run as Windows services and may spawn child processes for on-demand scans; the main sgav-svc.exe ensures continuous protection even when the UI is closed.
