Antivir ne fonctionne pas correctement

Bonjour,
Je suis resté deux semaines sans antivirus, je sais c'est mal ! J'ai installé deux fois antivir, mais à chaque fois ni l'udapter, ni le scan ne fonctionnaient, et impossible de fermer, je devais redémarrer l'ordi.

Alors la question que je me pose : suis-je infecté?

Voivi le rapport hijackthis :
