Pc ralenti...infection virus

Bonjour,
je suis sur le pc de mes parents (+de60ans...les parents pas le pc !!!) et leur machine est toute ramolo...il lui faut 1 bonne minute pour ouvrir une page internet. sitot je j'essaye d'en ouvrir plusieurs, il se bloque... je suppose qu'il a qq petits virus !
bref, il a securitoo.
j'ai fait un ccleaner.
j'ai voulu mettre en route AVG-antispyware, mais securitoo le bloque en me disant qu'il y a un win-32 dans le fichier d'installation et donc, me met la mise à jour en echec !
voici le rapport hijackthis. ( plus bas )
que puis-je faire pour redonner une nouvelle vie à cette machine ?
merci de votre aide.
