Welcome! Great community here, I'm sure you'll love it. Here we're going to need a little shell (command-line) use, as this is a non-standard use case.
First backup stuff. System-changing scripts can and do break. While linux breaks really nicely and informatively, it still breaks. 
Remember where you've downloaded the script to. I.e if it's in Downloads/remove_amd_message.sh, remember that.
Open a terminal (Ctrl-Alt-T), it's a little purple box. Then type:
Code:
sudo Downloads/remove_amd_message.sh
replacing the path with what you remembered.
Enter your password when prompted (you can't see it, just type and press return), then you should be okay to go.
