Origins:   Fizzer is a mass-mailing virus which spreads through file-sharing programs such as Kazaa as well as by e-mail containing a file attachment with a .exe, .pif, .com or .scr extension.

Once a computer is infected, the virus will scan the victim's address book and send out infected messages using different subjects, message texts and file attachment names.

Fizzer also installs a keylogging program to record every keystroke as well as open a way to access a victim's computer over Internet Relay Chat, and the virus also regularly connects to a web page to try to download an updated version of itself.
