Salve a tutti ragazzi mi rivolgo ancora una volta a voi vi posto il log di hijackthis. Avrei bisogno di togliere programmi inutili all'avvio che rallentano soltanto il pc ma non so quali togliere, ho paura di far cavolate visto che l'ultima volta che ho fatto questo lavoro da solo ho cancellato qualcosa della scheda di rete che non funzionava più ;)
