Problema CPU occupata all'avvio da vari processi

[ligar]

Ciao a tutti. Il mio problema è questo: spesso capita che all'avvio e per i successivi 10 o 15 minuti il mio portatile vada in palla totale. L'utilizzo della CPU balza alle stelle e dal task manager viene fuori che tre processi in particolare rompone le scatole. Si tratta di svchost.exe(netsvcs), perfmon.exe e svchost.exe (secvcs), il primo dopo un po' si ridimensiona mentre aumenta di importanza l'ultimo. Ho provato a fare varie scansioni del pc sia col mio antivirus (Avira) che con altri antivirus e antitrojan online ma non è mai risultato nulla. Ho anche effettuato un controllo con hjackthis ma anche qui niente di rilevante a parte il driver della scheda audio che il sito di hjackthis mi riporta come da eliminare. Mi potete aiutare?
Grazie a tutti

Per sicurezza allego il log
