That was the time when I described to her that she needs to be guarded on the web by connecting via a virtual personal network or VPN. She replied to me by stating she has a very good anti-virus program and firewall to defend her presently, but hacking still transpired to her. I defined to her the variation of VPN from the Computer security tools she pointed out.
