Ciao diego21

quando si inserisce il log si dovrebbe indicare anche che tipi di problemi si riscontra

il log è pulito, quindi potrebbe essere tutto tranquillo, ma se il computer si comporta in modo strano non è identificabile dal log, ad esempio i virus infettano file di sistemi che nel log risultano legittimi. Quindi facci sapere

Nel frattempo installa un Firewall, dal log pare che non lo utilizzi, ti consiglio Outpost

e dovresti aggiornate XP con il service pack 3, fallo subito dal windows update, oppure scarica il pacchetto da questo indirizzo.
