Restore and exclude problem

i downloaded a script that i want to test in a game i play called csgo, but when i open it, it says that its not safe and they removed it. So then i looked on the internet for a solution. I tried going into quarantine, and restore and exclude, but for some reason i can only restore and not exclude. I click restore and it restores but when i try and open the script again it deletes and stops me from running it. I can restore and exclude other programs but i can only restore this one and not exclude. I have norton 360 premiere edition, please help.
