Stop Windows Defender deleting a legit VB script

Question

I have wrote a little script that will automate downloading and running a program, however when invoking the script from command line, Windows Defender will enter the scene warning user that malware is detected, disabling and deleting the script!

How can I stop Windows Defender deleting this script?

Code:

strFileURL = WScript.Arguments.Item(0) 'download url
strHDLocation = WScript.Arguments.Item(1) 'path to exe

Set objXMLHTTP = CreateObject("MSXML2.XMLHTTP")

objXMLHTTP.open "GET", strFileURL, false
objXMLHTTP.send()

If objXMLHTTP.Status = 200 Then
  Set objADOStream = CreateObject("ADODB.Stream")
  objADOStream.Open
  objADOStream.Type = 1 'adTypeBinary

  objADOStream.Write objXMLHTTP.ResponseBody
  objADOStream.Position = 0    'Set the stream position to the start

  Set objFSO = Createobject("Scripting.FileSystemObject")
    If objFSO.Fileexists(strHDLocation) Then objFSO.DeleteFile strHDLocation
  Set objFSO = Nothing

  objADOStream.SaveToFile strHDLocation
  objADOStream.Close
  Set objADOStream = Nothing
End if

Set objXMLHTTP = Nothing

Set WshShell = WScript.CreateObject("WScript.Shell") 
WshShell.Run WScript.Arguments.Item(1)
shell.SendKeys"{ENTER}"

Answer 1

The quick and dirty solution:

Split the script in two. One script for the download, one for the execution. Not very elegant, but effective. This way Windows defender is fooled.

Answer 2

The next time Windows Defender alerts you about the software, on the Action menu in the Alert dialog box, click Always Allow. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
