Impossible d installer un antivirus

Bonjour,
Il m'est impossible d'installer un antivirus
kapersky me met une erreur 1304
zone alarm arrete son installation a 6% après un message d'erreur
Avast s'installe mais après avoir redemarré je ne peux pas la lancer car quand je clique sur le logo avast il recherche la cible exe

je vous joint le rapport hijackthis
