[VIRUS] MON PC RAME

Bonjour, je pense avoir attrapé un virus sur mon pc (voir plusieurs) ce qui rend mon pc extrement lent. J'ai essayé de faire divers scan mais ca ni change pas grand chose j'ai l'impression. J'ai de plus une icone qui clignote ds ma barre des menus a droite ( un rond bleu avec un point d'interrogation et un petit rond baré, style sens interdit :p ).
Voici le rapport HijackThis si ca peut servir :
