Salve, da stamani ho un fastidioso problema. Ogni 30 sec mi appare la finestra di avviso dell'antivirus che mi segnala la presenza di un trojan (sempre lo stesso file c:\windows\system32\perfc000.dat) . Clicco su delete e mi riappare all'infinito la stessa segnalazione. Che fare?
Allego il log di hijackthis, aiutatemi per favore
