Da qualche giorno mi arriva sempre lo stesso messaggio da un fantomatico indirizzo email ed ogni volta il mio antivirus AVAST mi avverte
avast! Antivirus: In arrivo messaggio INFETTO:
\zupd02.zip#206834743 (Win32:Beagle-IA [Wrm]) e' stato cancellato dal messaggio

e mi chiede cosa farne del file infetto. Io puntualmente lo cancello, ed ho anche impostato dalle regole di Outlook di eliminarlo ogni qualvolta arrivi, ma niente, ogni giorno è sempre la stessa storia.

Il Pc per adesso pare funzionare regolarmente ed il Log sembra anche pulito ( a me).
Come posso risolvere?

In effetti questo reboot.exe non mi ha dato una bella impressione, adesso provvedo ad eliminarlo anche perchè guardando nella rete pare che sia responsabile di un problema al pc e cioè che provvede a spegnere randomicamente il pc, cosa che alcune volte succede anche a me e fino ad oggi non mi sapevo spiegare!
Grazie per il consiglio!
