ctfmon.exe error

I’ve installed both Comodo Firewall, Antivirus, and BOClean… Computer’s been running fine, just a small issue.

Now, whenever I start up the computer I get this error (It’s probably me mis-allowing a feature or something)

The title of the box is ctfmon.exe - Bad Image, the error message is: “The application of DLL C:\WINDOWS\system32\MSUTB.dll is not a valid Windows image. Please check this against your installation diskette.”

How do I go about fixing this? Any help is appreciated!
