ignore a threat

NIS detected a threat (I know what it is) and it WANTS me to remove it. Which I do not wish to do. I want it to ignore the threat. But there's no such option which imho is a big joke. Why ask me what to do if you're only going to let me remove it? C'mon.... Anyway I dont want to remove it. What can I do? I already added the folder to be excluded from sonar/autoprotect but it just keeps popping up every few minutes....
