A computer virus is a piece of self-replicating code that attaches itself to other programs and files. Its main goal is to spread but it will often have a payload which may damage the host computer by deleting files, corrupting files, modifying configurations, or formatting the hard disk.

A computer virus is really just a program that is able to "connect to" your computer. For example, think of your operating system. It is composed of so many different components. When a computer virus enters your computer, it is compatible with some of the functions of the operating system. Therefore, when you turn on the operating system, the virus also turns on. In Biology terms, it basically lives parasitically with the operating system since it disables it from functioning and also lives comfortably within it.

Some strong Computer Viruses disable the system restore function too. Since the system restore function will restore the computer back to a period where it was normal, destroying the virus, the virus will "hook" to one of the system restore components and disable it from functioning too. To solve this problem, enter into safe mode, which will allow only the most basic computer functions to operate, and then utilize system restore.

Most people mean by a program that you get in some manner that can look at files on your computer or really do whatever it's made too. Though viruses such as rootkits are VERY rare, they allow the person to completely control your computer and even worse are discussed as your OS it's self.
