Pop up d'avast permanents

Bonjour,

Depuis quelques jours j'ai un probleme avec mon pc..
des pop up d'avast surviennent sans arret déclarant que des virus sont trovés dans mon ordi, mais également d'autres me signalant "trop de mails identiques envoyés"...
De plus j'ai aussi noté, un ralentissement considérable de mon ordi, notamment sur internet, avec des pages qui ne veulent parfois meme plus s'ouvrir..

j'ai fait un hijackthis, est ce que qq1 peut m'aider à l'analyser, et à trouver une solution à mon petit pb?
