Hola, hace cuestion de una semana que me aparecen en mi PC algunos mensajes de infeccion de mi computadora por virus, y me dice que tengo que descargar un antivirus que me remediara la situacion, pero despues me lo quieren vender, esto era al conectarme a internet, pero ahora esto sucede a cada momento (aun sin estar conectado), se me desaparecio el fondo de entrada y me aparece ahora el mensaje de warning del antivirus (spy sheriff o algo asi), ademas instale el norton 2005, el cual me elimino algunos virus que si tenia, pero me aparece el mensaje que tengo infectado el winini.dll con el w32.desktophijack y no lo puedo eliminar, tambien instale el ewido security y me detecta unos trojanos, aparentemente los elimina pero vuelven a salir, y el computador se hace cada vez mas lento, les ruego me auxilien en este problema, envio mi log,
gracias...
