I-Worm.Kazus.b

Worm Kazus spreads by e-mail in messages with infected attachments. It also can distribute itself via IRC chat protocol. It is primarily designed to send itself to users found in the Microsoft Outlook Address Book by e-mail. However, in most cases this function doesn't work well. Kazus connects to the Internet via IRC protocol and can be fully controlled by the author through it. The worm also changes browser settings.
