Virus---

A virus (from the Latin virus meaning &quot;toxin&quot; or &quot;poison&quot;), is a sub-microscopic infectious agent that is unable to grow or reproduce outside a host cell. Each viral particle, or virion, consists of genetic material, DNA or RNA, within a protective protein coat called a capsid. The capsid shape varies from simple helical and icosahedral (polyhedral or near-spherical) forms, to more complex structures with tails or an envelope. Viruses infect all cellular life forms and are grouped into animal, plant and bacterial types, according to the type of host infected.

Examples of common human diseases caused by viruses include the common cold, influenza, chickenpox, diarrhea and cold sores.

If you mean Computer Virus---

A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The term &quot;virus&quot; is also commonly used, albeit erroneously, to refer to many different types of malware and adware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. Meanwhile viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer.

How Do Computer Viruses Spread?

Computer viruses usually spread in one of three ways: from removable media; from downloads off the Internet; and from e-mail attachments................................

Answer 3

Something that can damage your computer.

Answer 4

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.

A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.

Viruses are most easily spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it&#039;s from and you are expecting it.

Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.

Viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.

Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.

Answer 5

Viruses :

Programs that infected other programs, adding their own code to them to gain control of the infected files when they are opened.
