Virtual: The word "virtual" can have many different meanings, but in computer/tech terms, it refers to anything on the computer or on the Internet that is a representation, or "virtual" version, of the same thing in the real world. So a computer program that provides a way to put up little "sticky notes" on your computer desktop would be providing you with "virtual Post-Its." Virtual versions of a real-world item perform the same function as the real world item, at least to some degree, but usually do not have any actual physical presence.
Virtual Assistant: A virtual assistant is a rather recent phenomenon that has become very successful. A virtual assistant is a real person who performs computer-based services, as an assistant, in a telecommuting capacity. So you might hire a virtual assistant to do editing, figure checking, research, or to return phone calls and yet never actually "meet" your assistant. In fact, you and your virtual assistant may live many, many miles away from each other. A virtual assistant career is a great choice for the home office worker.

Virus Protection: Virus protection includes security measures such as a firewall, which prevents nonusers from entering the computer system or network, and virus protection software, which prevents viruses from being downloaded and installed onto a computer or network.
