Problème lenteur sur pc

Bonjour,

quelqu'un peut-il m'aider à analyser ce scan fait sur hijackys ?
problèmes rencontrés sur le pc :
lenteur à l'allumage, à la recherche de sites et de pages,
au bout d'un moment, sur msn, on ne peut pas parler avec plus d'une personne
pas possible de consulter internet en même temps que msn

merci beaucoup pour votre aide
