Ciao a tutti.
Da una settimana circa ho riscontrato un problema con la cpu del mio pc: dopo un po' che il computer è acceso, normali processi come messenger, firefox o wmplayer iniziano a occupare molta cpu, intasando completamente il sistema, con conseguente lag e rallentamento delle applicazioni.
Non riesco a capire dov'è il problema, ho già deframmentato i dischi fissi, fatto la scansione del registro con regcleaner e eliminato le chiavi inutili, fatto la scansione con ad-aware ed eliminato i file sospetti... ma il problema persiste. Il mio computer è un windows XP professional SP2 con 512 mb di ram. Qui posto il log di hijackthis, nella speranza che qualcuno mi possa dare una mano.

Ciao Wegente,

il log di hijackthis non presenta cose strane.
L'unico consiglio che mi sento di darti è di cambiare il firewall (sygate è andato in pensione, purtroppo). Personalmente ti consiglio Comodo.
Qui e qui trovi discussioni in merito ai firewall.
Quest'altro è un topic dedicato ai software free per la protezione del pc.

Se, poi, vuoi fare altri controlli, fai questi passaggi:
Scansione con FindAWF
Scansioni con GMER e posta i logs su FreeFileHosting come indicato qui.

PS: se vuoi, puoi presentarti qui
