Chapter 20. A Network Security Primer > Fighting Against Viruses

Fighting Against Viruses

Another threat to your network’s security is the virus. A virus is a self-replicating piece of software code. Because a virus can copy itself, it can easily (and unfortunately) be spread from computer to computer.

Viruses can be spread on floppy disks and other removable storage media. If you take an infected disk out of a computer and place it in another computer, you have spread the virus. Computers can also become infected with a virus that spreads over the network because of infected shares.
