Stamane ho scoperto di avere sul pc il trojan csrcs.exe che si annida nella cartella system32 di windows, dopo aver notato un utilizzo anomalo della CPU dal task manager, sempre tra il 70 e l'80%...
ho quindi individuato il file, eliminato e poi ho aperto il registro di sistema ed ho eliminato la chiave che lo fa partire in automatico ad ogni avvio
ho letto varie procedure in rete che consigliavano di procedere così
ho quindi cercato eventuali altri file sospetti (in rete c'era scritto di un file KHQ.exe, ma non ho trovato nulla sul pc) e poi ho riavviato.... ho ricontrollato il registro di sistema e la chiave non c'è più, tuttavia il pc continua ad essere lento e non avendo nulla di aperto la CPU si mantiene "utilizzata" tra il 65 ed il 75%
ho quindi fatto un altro log con hijackthis, analizzato online ma niente di sospetto...
ho fatto una scansione con AVG Free 8.5 ma nessun risultato...
la mia macchina è un AMD Phenom 9550 Quadcore 2.20 Ghz, 2Gb RAM, con installato Windows XP service pack 3
posto qui sotto l'ultima scansione di hijackthis...
qualcuno ha qualche idea di come risolvere questa cosa della CPU "intasata" ???
