Une nouvelle analyse

Bonjour,
J'ai des problèmes sur un ordinateur, en particulier pour les connexions au réseau. Je ne sais pas si cela provient de virus ou d'autres programmes malfaisants, mais je serais heureux d'avoir une analyse du log fourni par hijackthis, pour éviter de lancer au démarrage des programmes inutiles ou même malfaisants.
Avec tous mes remerciements,
o_parodi
