A Virus Is: A program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. The term "virus" is commonly but erroneously (Incorrectly/ Wrongly) used to refer all types of malwares. You should be careful in the following points.
> Virus, Trojan Horse and Worm are terms often used interchangeably.
They are all Malware. But they are not the same.

VIRUS does have a abbreviation. VIRUS stands for "Vital Information Resources Under Siege" based on the activity it performs and the vital data it destroys. it's not an abbreviation, it was adopted from the term virus.(Like flu virus).
All computer viruses are manmade. Viruses can also replicate themselves. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it actually cannot infect your computer unless you run or open the malicious program. It is important to note that a virus cannot be spread without a human action (such as running an infected program). This means the virus can exist on your computer, waiting, but not infect your machine until you run or open the program. Because a virus is spread by human action people will unknowingly continue the spread of a computer virus by sharing infecting files or sending emails with viruses as attachments in the email.
A virus typically 'infects' another file. So, for example, you could download a free game from a website, and it could be infected with a virus. When you start your game, you are also letting the virus run. It is not safe to download just anything from any website (or peer-to-peer file-sharing system) without taking precautions.
