  • Be fore trying to writ CmdLets you need to learn how to use CmdLets.  You must supply values for a CmdLet.

    Also do not make the new user mistake of trying to wrap every CmdLet in a function.  It serves no purpose.

    You must start by learning PowerShell. Without any basic programming training you will find learning and using PowerShell beyond just typing at the prompt a very painful learning experience.

    First go here: Microsoft Virtual Academy - Getting Started with Microsoft PowerShell

    Also be sure to always read the help for each item you wish to use.

    help about_functions

    You also need to read the error message carefully as they tell you exactly what is wrong and much of the time tell you how to fix the issue.  That is the case here:

    New-CMAntimalwarePolicy : Missing an argument for parameter 'Name'

    It is telling you that you have not supplied a value for the parameter called "Name".  In your code you have not supplied values for any of the parameters you have used.
