The original video behind this clip is not documented, so it is best known online as a Portuguese meme sound rather than as a line from a film or television show. Its title gives away the joke, which helps it travel in short videos, reaction edits and soundboard collections where a recognisable warning works better than a longer explanation. Because the situation is universal, anyone who has guarded a computer from a sibling, a pet or a curious friend, it keeps getting reused whenever a new clip needs a firm but funny way to say hands off.
