ciao, quelli che mi hai detto li ho rimossi, ma nel frattempo mi è apparsa una finestra che mi chiedeva di installare Drive Cleaner. Io gliel ho negato e mi è apparsa una pagina che mi ha scaricato Del Internet Dialer, che ho subito eliminato... ora ho il processo svchost a 98 e il pc che va lentissimo, mentre Panda (di cui ho installato oggi la nuova versione) continua a trovare virus. Posto un nuovo log di hijackthis. Grazie per l'aiuto.
