CPU intasata! Navigazione impossibile!

[gione11]

Ogni tanto mi si attiva un programma che si chiama "Win9x.exe" ke ha come effetto di occupare tutta la CPU e di impedirmi la navigazione in internet. Togliendolo dai programmi lanciati all'avvio non si ottiene niente perchè dopo un certo tempo ricompare lo stesso. Terminando il processo con Task Manager tutto ritorna a funzionare ma dopo un pò riappare.Win9x si trova nella cartella C:\Windows\System32. L'antivirus Norton non me lo segnala.Che fare?

VVoVe: Grazie

Mi sembra logico che adesso devi cancellare il file:
C:\WINDOWS\System32\Win9x.exe
Fatto questo scarica RegCleaner e prova a vedere se ti cancella le chiavi inutilizzate del programma che SICURAMENTE ha intasato un pochettino pure il registro!!!
Senò passi al piano "B" cioè rimozione a mano delle chiavi inutilizzate con MOLTA prudenza!!!

[gione11]

Grazie! Ho dovuto cancellare le chiavi con hijackthis, ma ora sembra funzionare tutto bne!.
