Analyse d'un scan hijackthis

Bonjour,
depuis une semaine mon navigateur est très très lent j'ai donc fais un anti virus (avast) qui n'a rien détecté et j'ai vu sur le forum qu'il fallait faire un scan hijackthis ce que j'ai fais mais je ne le comprend pas.
si quelqu'un pouvait m'aider se serait gentil

merci d'avance.
