Central Command, a leading provider of PC anti-virus software and computer security services and its partners today announced the discovery of a new Internet worm that pretends to be an e-mail message from Microsoft Corporation's technical support department. The new worm named Win32.Invalid.A@mm carries a destructive payload that can render executable (.exe) applications unusable by encrypting them with a random encryption key. This mass-mailing worm first verifies that an Internet connection is available and if a connection is established it searches for all files starting with the extension ``.ht*'' in the My Documents folder.
