How do I get rid of it?

Just like so many of the other files I've written about so far, ctfmon.exe is located in the c:\windows\System32\ctfmon.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!
