[Trojan] Norton, adaware, Spybot inefficaces

Bonjour,

J'ai attrapé un virus qui lance internet explorer sur une page avec en adresse marqué about:blank.
Je reçois plein de pubS douteuses.

Norton peut les repérer mais n'arrive pas à les supprimer.
Idem pour adaware, A²free et Spybot qui sucrent plein de choses mais ça revient toujours.

Voici ce que me dit Hijackthis :
