Bueno te doy la bienvenida al Foro de Spyware, te comento que encuentro un virus tipo gusano en tu sistema el cual puede que sea el culpable de estos problemas.

1- Inicia en "Modo a prueba de fallos" (modo seguro)

2- Prende la opción de "Ver archivos ocultos y del sistema"

3- Pasale tu antivirus de forma completa y elimina todo lo que encuntre.

4- Ejecuta el HijackThis y dale a estas entradas:
