Have you got Office with the text and speech installed / running
Basically it's part of the Office Xp/2000 alternate use inputs so if you loaded speech or handwriting recognition options, it's there.
Thor's Hammer is made by triCerat Software and is part of the Windows Terminal Server and Citrix MetaFrame systems. It is associated with and loaded with Ctfmon.exe from Citrix Systems, Inc
Ctfmon.exe monitors the active windows and provides text input service support for speech recognition, handwriting recognition, keyboard, translation, and other alternative user input technologies.
Thor's Hammer is the code that stores all elements in a self-replicating database called desktop2001 code named "Thor’s Hammer."
For example, if a virus attempts to run an executable it will fail. In addition, programs that users download from the Internet or receive by e-mail will fail unless they have explicit permission.
So it's actually not a bad thing.
