Image hors cadre sur l'écran

Bonjour,

J'ai comme l'impression d'avoir un virus sur l'ordi. en tous cas il est lent et par moment la taille des fenêtre est plus large que l'écran. Je ne peux pas fermer la fenetre autrement que alt f4. Ci dessous le hijack fait il y a cinq minute.

Comment je peux contrôler la présence d'un processus qui est une menace en temps réél?
Un mail peux t il etre un virus qui ne fonctionne qu'une seule fois lorsque l'on clique dessus ?

Merci pour votre aide
