I-Worm.Niqim

Worm Niqim uses several ways to spread. It sends itself in infected e-mail messages to all addresses found in the Microsoft Outlook Address Book. It infects mIRC chat application and ICQ messenger to distribute itself via chat networks. It also places its files to shared directories of the KaZaA peer-to-peer client, so other users could download and run infected executables. In some cases the Niqim tries to format the main hard disk on next PC's startup.
