On-demand scanning methods and how they are defined
The on-demand scanner uses in-memory-process scanning and incremental or resumable scanning.
In-memory-process scanning
This method examines all active processes prior to running the on-demand scan task. Any detected potentially unwanted process is highlighted and the process is stopped. This means that a single pass with the on-demand scanner removes all instances of a potentially unwanted program.
Incremental or resumable scanning
This method allows you to limit when on-demand scan activity occurs, and still scan the entire system in multiple sessions. Incremental scanning can be set by adding a time limit to the scheduled scan. The scan stops when the time limit is reached. The next time this task starts, it continues from the point in the file and folder structure where the previous scan stopped.
