Co-op hack not working

Hello everyone, so i have tried doing a lot to get this hack to work, but it seems as if it just doesn't like me. Every time I install the hack and go to open it, it auto-deletes. Anyone have some sort of reasoning for this, and possibly what to do to solve it. thanks for any support

auto-deletes? this probably is your anti-virus

Or someone has acess to your computer lolz !
