This section describes how to perform a virus scan immediately.
Procedure
Choose Settings > Data Security > Antivirus Service > Namespace Scan Tasks.
Select a desired account from the Account drop-down list in the upper left corner.
Select a namespace scan task for which you want to perform a scan immediately and choose More > Scan Now.
The Scan Now page is displayed on the right.
In the On-Demand Scan Policy drop-down list, select a desired on-demand scan policy. The system immediately scans the namespace for viruses based on the selected on-demand scan policy.
This parameter needs to be set only when no on-demand scan policy is configured for the namespace.
Set the duration, which can be Custom or Until the scan completes. The configured duration takes effect only for the current scan.
