Hola Fulgore, bueno antes que nada te pido perdón por haber tardado tanto en responder, realice los pasos que me indicaste y limpie todos los virus y el registro, pero el S.O me seguía dando errores de software, al tener 2 discos uno de 40gb con el S.O y otro de 160 gb de almacenamiento me decidi por formatear el disco de 40gb instalar el xp sp2 nuevo y actualizarlo con el url que me incaste (esta de p.m.) mucho más comóda que tener que andar buscando por la página de update de microsoft, como no he formateado el hd de 160 gb he realizado otro scaneo online con el kaspersky y no me ha encontrado ningún virus a continución te pego el reporte, solo una cosilla he cambiado de firewall estoy probando el ZoneAlarm Pro versión:6.5.737.000, y me detecta muchos intentos de conexión (en 2 días me ha detectado 3500 intrusiones de las que 40 las identifica como de gravedad alta, esto es normal???), con el agnitum outpost 4.0 pro no tenía casi avisos ni cuando estaba infectado con los virus.

Gracias, un saludo.
