Pc lento y algunas acciones no se llevan a cabo

Hola @SanMar !

-Te comento que hice todo rigurosamente, según quedó indicado, CCleaner lo eliminé usando Revo. -Creé un backup del registro con Delfix. -Copié FRST al escritorio, cree el archivo “txt” con el script y lo dejé en el escritorio también.

En el último paso tuve un problema, ya que al iniciar frst y darle “fix”, el programa inició, todo parecía bien, pero al cabo de un rato se congeló y quedó en modo “No responde” demasiado tiempo. en el Log, creo que se nota que no terminó todo su proceso. Al quedar pegado, quedó en pantalla que lo último que estaba haciendo era “fixing” no se qué…

Te adjunto el Log:
