Problème de sécurité

Bonjour,

je me permets de solliciter votre aide car j'ai de nombreux problèmes de sécurité et avant d'en arriver à la solution ultime (jeter le pc par la fenêtre ?? J'y songe ! Non formater !) je voudrai savoir si c'est réparable.

Je vous copie ci-dessous le rapport du gentil HIJACK :
