prima di postare il log una domanda:
come antivirus ho avira premium security suite e poi faccio delle scansioni con spybot e malwarebytes.
vanno bene o devo installare qualche altro programma? se nessuno dei tre trova alcun virus vuol dire che il pc non è infetto?

ecco questo è il log di HijackThis
