That was the time when I described to her that she wants to be safeguarded on the internet by connecting through a digital private network or VPN. She replied to me by expressing she has a very good anti-virus software and firewall to protect her already, but hacking nevertheless took place to her. I described to her the difference of VPN from the Personal computer defense tools she described.
