Vidéo internet saccadée , son distordu

Bonjour,
depuis 24 h environ je ne peux plus regarder une bande annonce sur in internet sans que la séquence ne soit saccadée avec un son distordu . Je sais que j'ai été infecté par un adware Gibmedia. J'ai peut-être eu une attaque alert security windows.

Voici le rapport de MBAM :
Version de la base de données: 3363
Windows 5.1.2600 Service Pack 3
