Buongiorno a tutti, da qualche giorno il PC - Windows7 Professional SP1 - è lentissimo e la CPU è fissa al 100% con due voci svchost.exe costantemente sopra al 30%.
Ho fatto scansioni con due antivirus e trojan ma non ha trovato nulla.
Provo a postare la scansione con Hijackthis sperando che qualcuno possa aiutarmi:
