Se me ha colado algún virus. Desde hace pocos días he notado modificaciones en algunas aplicaciones. Me he quedado sin audio y se me bloquea la conexión a internet y debo reinciar. He descargado todos los programas antitroyanos que recomendais. Tambie en modo a prueba de fallos. ¿hay alguna solución?
Gracias

Hola vicentjanuary,

Te recomiendo usar la opción de "Restaurar el Sistema" a un día antes de empezados los problemas.
