Description

The Remove-MpPreference cmdlet removes exclusions for file name extensions, paths, and processes, or default actions for high, moderate, and low threats. If you attempt to remove an exclusion that is not in the list, this cmdlet reports the error.

Examples

Example 1: Remove a folder from the exclusion list

PS C:\> Remove-MpPreference -ExclusionPath "C:\Temp"

This command removes the folder C:\Temp from the exclusion list.

Optional 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.
