Ovviamente il mio sistema windows é più pulito del sederino di un neonato appena cambiato, tra l'altro siccome sto usando solo linux la cosa suona stranissima: ho inviato una mail ad un tizio bloccata da un filtro antivirus? Come mai?
Andando a leggere il log in maniera più approfonidta si va a capire che a questa e-mail era allegato un file messagge.scr contenente il virsu netsky-p.
Qua il mistero s'infittisce. Semplicemente ho avvisato tutti i miei amici di controllare il proprio sistema e di eliminarmi dalla rubirca di windows.
Una cosa del genere mi mancava. Quanto mi piacciono i misteri :D
