to copy itself into other programs stored in your computer, and
then spread itself from one computer to another.
• Virus programs are written by computer programmers or
hackers--usually with malicious intent--and are typically
spread through shared documents, spreadsheets, executable
files, software programs, or floppy disks.
• Viruses can do anything from displaying random messages or
sounds, to damaging data, to wiping out the contents of your
hard disk.
