Pc lent, mon hijackthis...

Bonjour à tous,

plusieurs petits soucis:
- des onglets s'ouvrent tout seul lorsque je navigue sur internet
- j'ai depuis quelques temps mon processeur qui tourne à fond les ballons alors que rien n'est censé être ouvert
( gestionnaires des taches, uc: 93 qui retombe entre 50 et 58 quand je l'ouvre, je n'ai que firefox d'ouvert si j'ouvre autre chose je ne peux plus rien écrire sur FFox et ma mémoire physique est à 53 %, quand au processus 70, comment savoir ceux qui sont utilent de ceux qui ne le sont pas ? )

J'ai lancé avast hier soir et au bout de 4 heures je n'était qu'à 3 ou 4 % de l'analyse

j'habite dans une ville ou internet et un luxe, je suis à 1 Méga de connexion !!!!!

Si vous pouvez m'aider se serais sympa, très sympa,

merci

Je poste un rapport hijackthis:
