1. Need a LOT more information to be able to help with this.
2. The concept is a Low-Risk Process
3. You don't. Nor should you. During an On Demand Scan it is normal for it to consume 100% of CPU resources. The process is throttled with a lower process priority as long as you don't pick "Normal". (Below Normal is default). This makes the process yield to pretty much everything else on the system. The CPU wasn't a consideration in the ODS scan design only whether it yields to the user experience. This is a far superior way to handle things over older ways (like everything prior to 8.8).
