==================================

Con la funzione TROVA di Windows, cerca ed elimina questi file,

==================================
NAKGG.DLL
==================================

in modalità provvisoria svuota la cartella c:\windows\TEMP con tutto quello che c'é dentro, la cartella TEMP deve risultare vuota

al termine utilizza i programmi AD-AWARE e SPYBOT indicati in questo articolo
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=388&SH=N

sempre in modalità provvisoria fai una scansione Antivirus.
