Multiples problèmes

Bonjour,
j'ai pas mal de petits problèmes sur mon Pc, tout d'abord sa connexion est devenue très lente du jour au lendemain, sa force du signal est toujours "faible", de plus lorsque je me dirige vers poste de travail ou encore dans mes documents le PC a du mal a ouvrir les dossiers, et se met souvent en "ne répond pas", ça commence à être pénible!
J'ai fais une défragmentation, un scan ... mais toujours rien !
J'ai essayé HijackThis et voilà ce que sa donne : Que dois-je faire maintenant ?? Merci d'avance !!
