Ciao,
innnanzitutto vi ringrazio per il servizio: siete davvero gentili.
Il problema riscontrato è dovuto ad uno spyware. Ho installato WebMediaPlayer pensando fosse semplicemente una radio per internet e lo è, ma racchiude anche una piccola e poco carina sorpresina
. Clamwin e Spyboot non lo rilevano.
Il sistema operativo è Windows XP e sono installati ZoneAlarm e Avast. Da un giorno il Centro di Sicurezza PC di Windows avverte che non è attivo nessun firewall anche se ZoneAlarm è funzionante e continua a lanciare i suoi messaggi di alert.
Lo spyware rileva il tipo di pagine che visito, quindi apre delle nuove finestre del browser in cui mi fa vedere delle pubblicità correlate al contenuto di ciò che sto visitando al momento. Alle volte compaiono delle pagine in cui mi si dice che il mio pc è infettato e quindi mi propone di fare delle scansioni on-line.
Come browser uso Firefox 2.0.0.14. Internet Explorer è installato ma lo utilizzo solo quando è strettamente necessario.
Ho notato (empiricamente) che se in Firefox disattivo JavaScript lo spyware non è più in grado di aprire le sue finestre.
Il log è il seguente:
