[hijackthis] Pc Lent

Bonjour, depuis ce matin j'ai un problème. Mon PC est extremement lent. Je n'arrive plus à naviguer, et le PC finit par planter. J'ia onc fait une analyse Hijackthis, soupçonnant un virus. J'ai donc fait une analyse hijackthis, mais n'étant pas très calé, je ne sais interpréter les résultats.
pouvez vous m'aider ?

Merci d'avance.
