Virus inconnu

Bonjour,

j'ai un problème avec un virus assez virulent. Voici les symptômes:

-Au démarrage, un tas de caractères apparaissent et disparaissent;
-La résolution d'écran change;
-De petites vagues bleues apparaissent sur les fonds noirs et des vagues jaunes sur les fonds clairs;
-Parfois l'ordinateur gèle complètement.

J'ai déjà scanné avec plusieurs anti-virus et anti-spy-wares: House Call, Avira, PC Cloud Cleaner, Ad-Aware, Malwarebytes, Spy-Bot S&D et fait un nettoyage avec CC Cleaner.

Plusieur fois, ça a semblé avoir marché, puis les symptômes sont revenus par la suite.

Ensuite j'ai vu un conseil sur un autre billet pour un problème similaire (https://forums.commentcamarche.net/forum/affich-1341750-resolution-d-ecran-qui-change-un-virus
qui disait d'essayer hijackthis si rien ne marchait.

Alors voici la copie du log mais je n'ai aucune idée de ce que ces données signifient, est-ce que quelqu'un peut m'aider? Est-ce qu'un de ces fichiers est un virus?
