Problema CPU 100%

[dany3000]

Ciao a tutti,

ho un problema. L' utilizzo della CPU del mio pc sale al 100% e si blocca tutto anche quando non ho un granchè aperto!
Questo non l'ha mai fatto fino a ieri!

Non so se è sempre dovuto all' utilizzo alto della CPU, ma anche quando apro canzoni e video l'audio di questi va a scatti!
Così ho pensato di scaricare Hijackthis e questo è il log:

antivir è configurato come da guida (vedi firma)? hai fatto una scansione completa?

[dany3000]

Il log l'ho messo solo perchè forse potrebbe servire, ma quello che mi servirebbe sapere principalmente è perchè il mio pc fa così e come risolvere.
Grazie per la risposta

PS: Sto provando a fare una scansione con Avira
