VIRUS

A computer virus is a piece of software that can be attached to another program or file. This program or file is said to be the host. Much like a human virus infects the body by attaching itself to a cell, a computer virus may attach itself to a file that is downloaded and installed on your computer. The virus spreads when the infected file is passed from system to system. Normally viruses are written to do harm to your computer, like destroy system files.

A computer virus is a type of malicious software that once activated, will replicate itself from folder to folder, inserting its own code. A virus can spread rapidly and will usually infect a system with the intention of stealing personal and financial information, sending spam or locking the system down.
