A virus is a piece of code that attaches itself to an existing computer program. The virus then changes the program and continues to multiply and spread to other computer programs. The goal of the virus is to harm your computer or to steal information, such as passwords, financial information, or other critical information. The speed of which a virus spreads can be fast or slow, or it might not spread, especially if there is a mistake in the code. Sometimes viruses can remain "dormant" in your computer for a period of time before it becomes activated. When this happens, the virus may delete important program files that your computer needs to operate smoothly.

A worm, on the other hand, is a computer program itself. Unlike a virus, it does not have to attach itself to another program to multiply. It is independent. A worm is able to spread by finding weaknesses in a computer's network. The speed at which it spreads can be incredibly fast and could affect a whole company's network, for example, in seconds.
