Analyser rapport Hijackthis

Bonjour, Bonsoir.
Je souhaiterais que vous m'aidiez pour analyser mon rapport HijackThis car mon PC est infecté : Fond d'écran inchangeable affichant " your system is infected" puis des instructions etc. Plein de fenêtres s'ouvrent (notament d'un antivirus installé tout seul ) , je ne peux plus ouvrir Google Chrome et d'autres applications, Antivir a trouvé une trentaine de trojans, d'infections...Etc et je ne peux plus ouvrir le gestionnaire de tâches!
En bref mon PC est un peu pourri , j'ai des alertes qui s'ouvrent toutes les 5 minutes donc si vous pouvez me donner un coup de main, je vous remercie mille fois ;)
Voici mon rapport :
