Internet rame ordi surchauffe icones disparus

Bonjour à tous !

Comme une débutante j'ai lancé un fichier exe (mais il venait d'un ami qui est sur mac, qui me demandait de vérifier que l'outil fonctionnait bien, et qui m'a garanti que c'était un fichier propre... Mais en fait non... Merci copain...). Le fichier ne s'est pas exécuté 'visiblement' mais mon ordi s'est mis à ramer d'un coup, le ventilateur à tourner à bloc, et internet à ramer. En gros mon ordinateur fonctionne bien sauf le net (les logiciels comme toshop ou dream fonctionnent normalement).
Qui plus est, mes icônes ont disparus (le bureau dans les icônes de lancement rapide, le poste de travail, l'icone memory stick)...

J'ai lancé un spybot S&D, il m'a trouvé pas mal de malewares et de trojans (je pense que le virus en a balancé partout, c'est comme si lors de l'exécution du fichier exe ça s'était propagé partout...). Pendant la première execution, l'ordi a affiché un écran noir, m'a affiché un message genre "surchauffe" et a redémarré (enfin a tenté de redémarrer, l'écran était noir). Du coup j'ai branché mon ventilateur histoire de le rafraichir...

Voici mon Hijackthis :
