This is an extremely dangerous Internet worm, which spreads by e-mail in messages with infected attachments. It installs itself to the computer and starts its spreading routine. It sends infected e-mails to all addresses found in the Microsoft Outlook Address Book. It also connects to some web servers and infects local files written in Visual Basic Script language. The worm has a payload: it attempts to remove built-in PC's software and erase all the data from hard disks. Then the infected PC cannot boot at all and in some cases needs to be replaced.
