Description

The Start-MpScan cmdlet starts a scan on a computer. The cmdlet performs scans for the path you specify.

Examples

Example 1: Start a scan

PS C:\> Start-MpScan

This command starts a scan on the computer on which you run the cmdlet.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Specifies the maximum number of concurrent operations that can be established to run the cmdlet.

The throttle limit applies only to the current cmdlet, not to the session or to the computer.
