Stop a Running Scan
When you stop a scan, Nessus terminates all tasks for the scan and categorizes the scan as canceled. The Nessus scan results associated with the scan reflect only the completed tasks. You cannot stop individual tasks, only the scan as a whole.
For local scans (i.e., not a scan run by Nessus Agent or a linked scanner in Nessus Manager), you can force stop the scan to quickly stop the scan and terminate all in-progress plugins. Nessus may not get results from any plugins that were running when you force stopped the scan.
To stop a running scan:
In the top navigation bar, click Scans.
The My Scans page appears.
In the scans table, in the row of the scan you want to stop, click the button.
The Stop Scan dialog box appears.
To stop the scan, click Stop.
Nessus begins terminating the scan processes.
(Optional) For local scans, to force stop the scan, click the button.
Nessus immediately terminates the scan and all its processes.
