What does it do?
ctfmon.exe - it's an ever annoying helper tool that comes rather unexpectedly at times and liked by nearly nobody.

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.

Loads of information can be found on microsoft's site here.

Unless you're using anything in that list above you'll want to stop this file from loading!

How do I get rid of it?

Virus Precaution:
Just like so many of the other files I've written about so far, ctfmon.exe is located in the c:windowsSystem32ctfmon.exe. At the time of this writing there isn't any spyware, viruses or anything like that masking itself as this file. If you find any info on one then please let me know!
