What is a Computer Virus?

What is a computer virus? A computer virus is a program designed to compromise computer security and spread itself by first infecting executable files or the system areas of hard and floppy disks and then making copies of itself. Viruses usually operate without the knowledge or desire of the computer user and are a threat to data security. They also may slow down your pc or may corrupt specific files. Viruses often come through email messages but can also come from software installation or just from clicking on a website.
