Ciao a tutti da un po di tempo il mio pc accusa delgli improvvisi cali di prestazioni in alcuni casi è come se si avviasse qualcosa in background che mi mangia risorse fino quasi a bloccare il pc.
Ho già fatto una scansione com Malwarebytes ma è risultata negativa Ora provo a postare un log di Hijackthis Al momento non ci sono rallentamenti tutto sembra funzionare a dovere
SO win xp SP3
Ciao a tutti e grazie
