Gironzoli spesso sul sito di "ComingSoon"?
Ecco cos'è capitato a Paolo Attivissimo:
http://attivissimo.blogspot.com/2006/02/comingsoon-sparavirus.html

Pare che il malware che hai beccato sia essenzialmente un DIALER che prova a nascondersi spesso fra i files temporanei di Internet. Prova a fare una bella pulizia dei "temporanei" (meglio ancora: usa un programma come CCleaner oppure DiskCleaner, entrambi scaricabili da Aiutamici).
Magari ti va bene e lo fai secco per caso.
