1. MSN Messenger can be unticked but can sometimes return depending upon you running it.
2. Ctfmon is a process used by Microsoft Office for the Language Bar and Speech and Handwriting recognition . Whether you have MS Office or not, that process will be present with IE7 for IE7's Language bar.
If you don't need that functionality, you can stop it from starting up. From the Start menu, Control Panel then Regional and Language Options, then click Languages Tab, then Details, then Advanced tab, then put a check next to “Turn off advanced text service” and hit Apply. This removes ctfmon.exe from the running processes and from starting up on boot up.
If the file is named cftmon it is probably a Trojan.
