da un po' di giorni sto' impazzendo con il mio pc e sospetto la presenza di un virus. Ecco i sintomi: improvvisamente, ogni tanto si disattivano tutte le porte USB e il processo system sale al 99%. In ogni momento, se provo a lanciare Avenger o Process explorer questi vengono killati. Se provo ad eseguire una qualsiasi ricerca su internet per process explorer o provo ad andare nel sito di download si chiude il browser (sia Explorer 7 che Firefox). Ho eseguito la scansione con AVG e AVG antirootkit, Kaspersky on-line ma non hanno rilevato nulla.
Di seguito riporto il log di Hijackthis:
