When an On-Demand Scan is running, it can only be stopped locally on the system by the end user via the Endpoint Security Console. The scan cannot be stopped from the ePolicy Orchestrator console. For instructions on how to configure the On-Demand Scan policy to allow end users to pause or cancel scans, see https://kc.mcafee.com/corporate/index?page=content&id=KB89818.

NOTE: Only policy-based scans can be stopped; custom scans cannot be stopped.
