Depois de tempos vendo que minha busca do google estava infectada por algum malware de Anuncios, e que sempre que pesquisava algo, só ap��s uns 5 itens que realmente mostrava o que o google acha, os 5 ou 6 primeiros eram anuncios dessa extensão. Então tive que desativar todas minhas extensões ativas e descobri que os anuncios partiam dessa extensão, péssima, se a ideia é bloquear anuncios, pq essa m**rda me exibe anuncio nas buscas?
