Buenos días gente.

Kaspersky Total Security

• Disinfect and restart the computer

Try to disinfect without computer restart.
This method does not guarantee complete disinfection.

Ya se le ha dado a Disinfect and restar computer, pero sigue saltando el aviso cada vez que se reinicia el PC.

¿Alguna idea?

Un saludo.
