I-Worm.Nimrod

Worm Nimrod is an Internet worm that spreads using infected e-mails, through IRC channels and in file-sharing networks. It usually tries to look like an animation file and shows a fake error message when installing itself to the computer. It affects Microsoft Outlook mail client, mIRC and pIRCh chat applications and peer-to-peer software KaZaA and distributes itself using this software. The worm also copies itself to all available hard disks and tries to disable the keyboard and mouse.
