très fort ralentissement

[peedjee]

bonjour,

 

Un portable Acer Aspire 8920 présente deux symptômes :

 

- soit un fort ralentissement , il faut attendre une minute ou deux entre chaque action donc en genéral il faut rebooter.

 

- soit vitesse normale et de temps à autre un message de PC Tools (préinstallé je crois) :

ACTION MALVEILLANTE BLOQUEE

Spyware doctor a bloqué une action malveillante de SVCHOST sur (nom de fichier variable)

 

J'ai désinstallé Mcafee et Antivir ( je n'arrivais pas à mettre sa base de virus à jour) puis testé avec Avast , Ad-Aware, A-squared, Spybot...

Mais antivirus et antispywares ne détectent rien.

 

Quelqu'un peut- il m'aider ? merci d'avance à une ame charitable

 

Je joins le rapport Hijackthis
