Ciao,
il log é pulito...che problemi riscontri?

Al limite installa un firewall diverso da quello di windows
http://www.aiutamici.com/software/view.asp

Be per MSN non so che dirti....al limite prova a fare una scansione antivirus online:
BitDefender
http://www.bitdefender.com/scan8/
oppure
Panda

Se riscontrano infezioni postaci il log delle scansioni
