Virtual Private Network (VPN)
A Virtual Private Network (VPN) is a tool that allows the user to utilize a private network which is built over a public infrastructure (e.g. the internet). It enables the creation of a secure connection to another network over the Internet. This essentially masks the user's location and enables the user to browse the internet anonymously.
A Virus is a type of malicious software designed to spread from host to host and replicate itself by altering other software and inserting its own code. Viruses can cause software damages, steal or erase data and even cause a denial of service (DNS) incidents.
