Bonjour,

j'ai un pc qui rame constamment tout en ayant fais beaucoup de nettoyage (CCleaner, ad-aware, spybot, avast pro, spyware doctor, regsuprême pro, défragmentation avec Diskeeper 2008,...). Pour plus de détail,j'ai un PC HP Pavillon 745.fr 2200+ (1,8GHz)avec XP familiale, 512 mo de SDRAM DDR, DD de 60 Go partitionné en 2, et j'ai effectué une analyse avec HijackThis :

Je remercie bien la personne qui pourra m'aider.

Bonjour,

Apparemment clean.

Désinstalle correctement Avast! pour le remplacer par AntiVir.
Pourquoi changer ? Avast! vs AntiVir

Fais un scan complet puis poste le rapport en fin d'analyse.
AIDE : Tutorial sur l'antivirus AntiVir Personal Edition Classic

Salut, ok je fais ça et te reponds plus tard, merci.

No prob.

Salut comme convenu je te joins le rapport d'antivir.
J'ai effectué une analyse en mode sans echec et une en mode normal : rien trouvé :
