Virus pc qui rame

Bonjour,
Je ne sais pas si c'est un virus, mais mon pc rame depuis hier, jaimerais savoir si il y a quelque chose de louche dans mon rapport hijackthis
norton ne detecte rien, alors je me tourne vers vous
dans le gestionnaire de taches, mon explorer.exe prends 50% du processsus, je ne comprends pas
aussi, ma barre en bas (je ne sais pas quel est le nom de cette barre) ou l'on retrouve le menu demarer est bloquée, elle ne marche plus.
