That was the time when I described to her that she wants to be protected on the web by connecting by way of a digital private community or VPN. She replied to me by expressing she has a good anti-virus plan and firewall to safeguard her previously, but hacking nonetheless occurred to her. I discussed to her the difference of VPN from the Laptop safety resources she talked about.

Simply because of my friends’ predicament, I realized that numerous folks are unable to explain to the difference among anti-virus applications, firewalls, and VPN connections.
