Il log é pulito da spyware

Fai una scansione antivirus on line da questo indirizzo
http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym

se vengono rilevati virus significa che il sistema é infetto e il tuo antivirus e stato disattivato dal virus, in questo caso conviene formattare il disco fisso e reinstallare tutto.
