Inker.B is a specific script worm with a rich set of malicious functions. The threat written in Visual Basic Script language is an extremely dangerous variant of the similar Inker worm. It spreads in the Internet through IRC chats, by e-mail and via file sharing networks. Once executed, Inker.B starts to run its destructive payload. The worm terminates running software including certain multimedia and office programs, Internet messaging and system tools, antiviruses, firewalls and other security-related applications. It changes the Internet Explorer default home page, prevents standard system tools and some other programs from running, disables Windows Firewall and modifies essential system security settings. Inker.B also deletes some useful tools such as the Notepad and Calculator, uninstalls certain software and blocks access to major Internet search engines, security-related sites and various popular web resources. The worm performs several annoying actions. It swaps the mouse buttons, changes icons of various file types and hides the desktop. Inker.B compromises overall system security by enabling the Guest account and creating a registered user. It distributes infected files using mIRC and ICQ programs, Microsoft Outlook mail client, Kazaa, Morpheus, BearShare and Grokster peer-to-peer applications. The parasite runs on every Windows startup.
