Sera a tutti.. mi si e' ripresentato un problema che pensavo di aver risolto qualche mese fa (o forse ho ripreso lo stesso virus..).
In pratica il pc si congela, ma la maggior parte delle volte e' solo il mause (usb) a bloccarsi..Altre la tastiera senza fili..
Ho xp home sp3 amd athlon 5000+....e come consigliato da Alfonso, uso ccleaner, spywareBlaster, avira antivir, spybot , pc tools firewall e malwarebytes' anti-malware che aggiorno frequentemente e che non trovano nessun problema (o almeno cosi' dicono)..
posto il log di HiJackThis; .. .. .. potete cortesemente dirmi se c'e' qualcosa di strano o che non va'? Grazie in anticipo..

Se hai il sospetto che ci possa entrare qualche malware, allora ti conviene postar nella Sezione intitolata a "Virus, Sicurezza e Privacy".
Inoltre, non so quanto convenga effettuare il LOG di HijackThis utilizzando una versione BETA: ti suggerisco caldamente ri rifare il LOG usando la versione ultima attuale stabile e poi postarla nell'apposita Sezione del forum, specificando i problemi che incontri sul PC un poco come hai fatto pure qui.
