Naked

Worm Naked spreads in the Internet by e-mail. It comes in messages with infected attachments. When a user executes such attachment, the worm runs a fake animation application and sends itself to all e-mail addresses in the Microsoft Outlook Address Book. Then it removes all critical computer files. The worm doesn't install itself into the computer and runs only when a user executes an attachment. However, Naked still can destroy the operating computer, so the infected PC will not be able to load the OS and start any software.
