When the scheduled time for a scan occurs, the following happens:

  • Your McAfee software starts monitoring your computer for activity.
  • If no keyboard or mouse activity occurs for 10 minutes, your McAfee software then monitors for CPU use.
  • If CPU use remains under 10% for 10 seconds, the scheduled scan begins.
