How system utilization works

The on-demand scanner uses the Windows Set Priority control setting for the scan process and threads priority. This lets the operating system set the amount of CPU time that the on-demand scanner receives at any point in the scan process. The System utilization setting in the On-Demand Scan Properties map to Windows Set Priority control as shown in the following table.

VirusScan Enterprise process setting Windows Set Priority setting
10% Low
11% to 50% — ePolicy Orchestrator default Below normal
51% to 100% — VirusScan Enterprise 8.8 default Normal
