Downloaded program files endommagé

Bonjour,
voila j'ai une publicité qui apparait tout le temps sur mon pc et je n'arrive pas à la supprimer car elle ne dispose pas de croix pour la fermer, du coup, je suis obligé de faire ctrl+alt+suppr a chaque fois qu'elle apparait!!
du coup j'ai voulu regarder dans mon disque local si je pouvais retrouver ce fichier mais par hasard en regardant partout, j'ai été dans downloaded program files et j'ai vu que
{49232000-16E4-426C-A231-62846947304B} était endommagé

j'aimerais savoir comment réparer, s'il faut le réparer.
Je vous remercie d'avance

J'ai fait un hijackThis, au cas où cela serait utile, je suis pas une spécialiste de l'informatique lol
merci!!
