Il log é pulito da spyware

rimuovi WinOverBoost, non serve praticamwente a nulla, se non a sprecare risorse del sistema

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

se continua il problema, prova a farti prestare un modem adsl da un amico, prima di comprarne uno nuovo, nel caso il problema dipende dal modem.
