Newbie question: How to wait till the end of the script?

Hello,

I try to automate Malwarebytes execution, which I'd like to put within a .bat file executing some night tasks. I do my tests in cmd window.
The issue I have, is the script execution in background. I launch my script using following syntax:

"C:\Program Files (x86)\AutoIt3\AutoIt3.exe" RunMalwareBytes.au3

The script starts and executes in background giving me a hand in cmd window at once.

My goal is to execute this script in foreground, and to get a hand at the end of the script execution, not before.

I was not able to find the solution for this issue neither in documentation nor on the forum.

Could you please help me in addressing this issue?

Thank you in advance
