Scan hijackthis à analyser

Bonjour,
Mon PC ne me parait pas anormal dans son comportement, mais j'aimerai en avoir la certitude.
Du coup, je viens d'effectuer un scan hijackthis, mais je suis incapable d'interpéter le log, quelqu'un peut il me dire ce qu'il en est ? Ma bécane est-elle saine ou infectée ?

Un grand merci d'avance.
Bien à tous,
Looping.
