Ciao, spero riusciate ad aiutarmi.
Il problema è il seguente: il pc si riavvia costantemente quando sono su internet, da ieri, quando per errore ho lasciato aperte le porte del firewall per un'oretta ed è entrato qualche trojan.
Il pc tuttavia è stato ripulito con svariate scansioni con nod32, kaspersky, anti rootkit e vari toos specifici, ora nessun antivirus individua alcuna infezione, ma credo che qualche virus mi abbia corrotto dei file. Ho anche installato la patch di XP per ovviare al bug dell'RPC (Remote Procedure Call, che mi causava il conto alla rovescia con riavvio: risultato, ora dopo poco che sono su internet riavvia senza conto alla rovescia) C'è qualche soluzione diversa dal formattare? (Ho l'hard disk partizionato, per fortuna...)

Ecco il log di hijackthis:

Ciao, il log non evidenzia infezioni.
Ho alcune perplessita sul programma NME Alerts. Se non l'hai installato tu, rimuovilo.

Dovresti aggiornare il sistema installando il sp2.

Aggiorna il JRE alla versione 1.6.0_03 che trovi su questo sito.
