JS.Gigger.A@mm is a mass mailing worm that sends itself to all email addresses in the user's Outlook address book. It also uses a script file to spread itself through IRC if the mIRC client is installed.
Gigger also adds a line to the autoexec.bat file that will format the C drive on the next system reboot.
