Ordinateur et connexion lente

Bonjour,

j'ai un problème, mon ordinateur est devenu très lent d'un coup, et ma connexion internet également et en même temps.
j'ai essayé de scanner mon ordinateur avec Antivir, et MalwareByte, mais je n'ai rien trouvé.
Pouvez-vous m'aidez s'il vous plaît?

antivirus: Antivir
pare-feu: Kerio sunbelt personnel firewall

Je vous joint un log HijackThis

Merci.
