RatingCtfmon.exe activates the Microsoft Office Language Bar and the Alternative User Input Text Input Processor. Alex
Ratingit was a virus on my machine. I found it outside the windows/system32 folder Dan A
RatingCan either be part of the language bar, or part of spyware. Alcy
RatingIf you are using any of the IME language pack additions to the NT or XP operating systems this will be on your system. If you are unsure whether it is malware or not you can use Spybot S&D to toggle it off to see whether you notice any performance change (ie malfunctioning foreign language input), before deciding whether to remove it completely. NormalScience; Webmaster

RatingThis file like many annoying Microsoft files can be easily removed by deleting it from its folder and within a few seconds creating another file or folder named the same in the same place. If this causes a worry at all just delete the file or folder that you created to block it out. I found this works for this file Blownaparte
RatingCtfmon.exe activates the Microsoft Office Language Bar and the Alternative User Input Text Input Processor. -- that's no right, I not use office and I haven't installed it recelently (I use StarOffice) so I don't think that is a Microsoft Office component SeTZeR

RatingÜberwacht jeden Tastendruck auf dem Rechner...gut oder schlecht entscheidet der, der es installiert hat oder auch nicht ! Mick
RatingMany people confuse the legitimate CTFMON with the trojan CFTMON - make sure you read carefully. It's part of Office XP and not at all dangerous. It doesn't have any effect on performance either. Trying to remove it will only screw things up, so live with it. Dave C
RatingThere is another file with the same name. Its a keylogger program call Family keylogger. Could be dangerous if you did not install it. Defult key to unhide it is Ctrl+Shift+Alt+F. Nemesis
RatingI have office xp running on w2k advanced server. I frequently got blue screened when using Word,Terminal Services, MS Outlook, and IExplorer. (problem with the ntkernal the blue screen said.) I also notice bad lag in word just before the crash when i ctrl and drag something. I have since removed ctfmon.exe from the run section in the registry (backed it up first :P just incase) and no more word lag or blue screens. And i havent come across anything I want to do that removing this file seems to have messed up. Dude
Ratingwhen trouble with internet or any other process not running at normal speed I delete it from memory and then the slow operation works fine. I believe in my ase it is used to interfere with my work or backup operations. Hard to shut off. Usually loads when an office or IE window opens but pops up on its own when I am having difficulties. I believe it is hacker related. Larry
Ratingeaiest way to disable in WinXP...click start-run...type gpedit.msc and click ok...in the window that comes up, navigate to Computer Configuration\Windows Settings\Security Settings\Software Restriction Policies\Additional Rules...Click Action\New Hash Rule...click browse and select the ctfmon.exe file...click ok...log out and in again and it will never run again me
RatingI've stopped it from running using the task manager over and over again, but it just keeps coming back up. My PC has seriously slowed down, but that's about all it's done. Norton doesn't see anything wrong with it and none of my spyware/adware stuff does either. I've actually deleted this file and everything and it just won't go away! Emily
Ratingmost of this type of .exe files are harmless if in doubt, do not delete them, quarantine it paul
RatingThis is a part of Office XP and Windows XP. It's not dangerous, as you've no doubt read already. Additionally, it's not entirely necessary unless you're using speech or handwriting recognition. I have removed the file from starting on my system and suffered no ill effects. Justin Ellis, Trainer, The Computer Workshop, Inc.

RatingPart of Microsoft Office Language Bar and the Alternative User Input Text Input Processor.. uses such a nominal amount of resources it's not worth your time trying to get rid of it. Dan Booth
RatingI had installed the Spanish language keyboard as an option, but CTFMON was interfering with a web-cam driver (huh?). Not dangerous, but annoying. SeamanTom
RatingSeems it stopped my ADSL connection to work ok. I desintalled the file (as per instruction given in other comments), and now it is working ok. I hope I will not experience any instability as described by Microsoft. Galaf59

Ratingas far as i kno there is a file ctfmon.exe that has to do with microsoft office programs such as microsoft word,microsoft powerpoint,etc. if u right click it then hit properties then the information on it pops up. on the tabs there should be one called version.click it and read the info on it. it should say sumthing like copyright microsoft corp. and stuff. so this is cleary not the one. maybe its cftmon.exe not ctfmon.exe. yet ive never heard of the trojan cftmon.exe dave has so however we may have gotten sumwhere today.....wat did we learn. CTFMON.EXE is with microsoft word,etc and CFT.EXE terrell
Ratingi try to close the language bar and it goes away then returns a couple of minutes later. Even when I delete the process it still returns. So I don't like it and it's made by Microsoft whom I totally do not trust!! anais

RatingThis file is needed for Voice Recognition. If you have the microphone taskbar loaded then this will be active. Gravity
RatingMy startup has been running very slow lately. When it gets to the welcome screen it freezes at that point and will not move any farther. So everytime I press crtl+alt+delete and what do you know ctfmon.exe is running. So finally I tried ending it and my desktop loaded up instantly. Now I have to use ctrl+alt+delete to end it every time I boot up my computer. Can someone help? Neil
RatingThis file appears after installing the Microsoft SpeechSDK. Unless you are using speech recognition software it isn't neccessary to run it. jon
RatingEND it. everything else will be fine. MK
Ratingit runs in background, starts on startup and it's impossible to disable it from starting normally. Spybot S&D identifies it as malicious software/spyware; it doesn't do anything useful, no program specifically requires it, so i blocked it and never had any error requesting it to run or anything of that kind, but instead less processes in task manager (: Serge
RatingIf it is in the system32 folder nothing is wrong but if its outside that folder it is probably a keylogger as Cupydon said
Ratingcan be removed by tweak-xp tools, remove it from the autostart menu, waste of memory and resources, nobody needs it. anonymous
RatingThis is used by Office Xp por Input reasons.. u can just search this file inside microsoft knowledge DB. But there is a new virus called Win32.GMSteal.

RatingCtfmon.exe monitors the active windows and provides text input service support for speech recognition, handwriting recognition, keyboard, translation, and other alternative user input technologies. It's an ever annoying helper tool that comes rather unexpectedly at times and liked by nearly nobody. Javed Iqbal Lodhi
RatingAnd if you find this service running or located outside \windows\system32 folder, then it is not the normal system file, you might want to scan your computer and get rid of it. Just in case you want to stop the service, if that is the normal service, control panel -- regional and language options -- languages tab -- details button -- language bar button and from there, disable it Javed Iqbal Lodhi
RatingI am not sure but diabling this file speed up my Internet access (dial up using GPRS), I am not sure why? Narinder Sahota
RatingIts a geniuine window process although there may be some trojan/viral variant of it if you have ability to set process prority set to low if high and if it returns to its original priority then its malicious Tony Stark
RatingWin32 system file. Its a geniuine window process it occours when you want to direct text from a web page directly to HD on a text document. There may be some trojan/viral variant of it if you have ability to set process prority set to low if high and if it returns to its original priority very quickly then i would say its malicious Tony Stark
Ratingmay have been replaced by one from a scumware program to use to host it speedball
RatingIt is a windows file. Uninstall office if it's a problem. Ach y fi
RatingNot dangerous but annoying. difficult to remove in my system... Daniel
RatingIf I understand MS correctly, you need this if you use the language bar to switch between keyboard layouts (as I do), or use other special input methods (speech recognition, etc) TGN
RatingSeems to be office releated, disbled it in msconfig and everything works still well. Ron
RatingThis causes a conflict with the latest version (8.0) of Dragon NaturallySpeaking. Scansoft recommends disabling the process - follow the directions posted earlier. Jon

RatingI had a nasty trojan which installed ctfmon32.exe - a big problem which self-replicated when I deleted it. But I also had the genuine ctfmon.exe in the same folder (no '32' in the name) which was fine. Don't confuse the two names. Tim
Ratingctfmon.exe is used to Inject a DLL named msctf.dll into all running processes. The msctf.dll resides within the System32 folder and is used to hook all WH_??? messages generated. I have hooked the API calls from msctf.dll and found that It hooks the keyboard, mouse and windows shell. Why, I don't know. As this is a trusted module installed by MS, I assume it is safe. But I also consider anything that hooks the keyboard to be a potential risk.  link for more info Anon Developer
RatingI found while surfing the web, a popup that asked if I would install this y/n. after accidently accepting by mistake. It changed my Active desktop, to some kind of spyware warning notice, put pornography links on my desktop and hijacked my browser start page. I found the infected file to be in memory, though, it was previously /system32/ctfmon.exe, now infected. So I attempted to delete only to find it recreated itself again! Then after afew reboots and removal attempts, at shutdown I see a window popup titled "Microsoft.corp.#" freezing up. (an trojan access attempt running hiddenly?)  link for more info Beware
Ratingsimply use winpatrol 9.0 to disable it. u can always enable it back if u encounter any trouble. Ralf
RatingSystem file :P Diego
RatingI know that everytime it came on it fragged my Internet connection... I slapped that bitch with a delete and haven't had a lick of trouble since. Scirocco GTX
RatingI have Microsoft Works and not Office installed on here. Might be part of Windows Update. It is in windows/system32. Causes a moment of lag during startup but does nothing else. Does not appear to be Spyware, Adware or virus/trojan/worm. Im staying Neutral due to the amount of lag it causes on my Laptop which does have Office. Systems with 256MB RAM will suffer more that systems of 1024MB (mine) Rahkin
RatingSlows my entire system and dsl connection, as soon as i end process with task manager everything is ok again! definately move where viable. Roy
RatingWinPatrol noticed it being added to Startup after I added speech recognition via Add/Remove Programs -Update Office XP Dennis
RatingEvery time I delete it from the "Run" area of the registry, it re-appears. I installed Ad-Watch, which reports ctfmon.exe trying to be put back into the registry whenever I reboot my PC and run an office application. Joe
RatingI run both Office 2003 and Windows XP SP 1 and ctfmon.exe is automatically loaded. If the file is stopped or uninstalled, speech recognition stops working although you can still train the system. The file on my system is only 13k bytes in size but uses 444 kbytes when running. Bill
Ratingif you go to search and search for msconfig.exe once you find it open it, look trough the different tabs until you find one with a lot of processes on it that u would usually find in your task manager (alt+ctrl+del) go down until you find ctfmon.exe disable it, when requested, (after closing the program) restart, should never bother you again. mick from australia
Ratingmy ctfmon.exe is for my japanese language pack that was installed on a fresh windowsXPpro it's been there ever since.. Never run Office before and never will. Open office is much better anyway. ctfmon in some cases is just language pack. Frank_Castle
RatingI don't have microsoft office xp and it is runig on my other users proccess. hi
RatingIf you installed Unreal Tournament 2004. You may have also installed the Speed Redist. as well. Check Add/Remove programs for speech enabled programs. midfingr
RatingThis file is both harmless and dangerous. A variant of coolwebsearch (one of the worst spyware out there) now uses the legit ctfmon to fiddle with IE explorer (not sure exactly how). Also other forms of spyware and malware are begining to use ctfmon.exe so if you don't use the legit applications of ctfmon then disable and or delete it. crazyed
Ratingit is incorporated with the "my doom" virus going to check it out this arvo, be back with info soon mate. Micky d!
RatingHier ist mehr im Spiel als ihr denkt.Ctfmon.exe ist ein Ueberwachungssystem, nur getarnt als Microsoft Office Bestandteil. Mit dem Taskmanager in die Quarataene damit ! Frank the Cracker
RatingDie ctfmon.exe ist ein Programm das zu Office gehört. Sie überwacht offene Fenster und dient der Spracherkennung, sowie der Zurverfügungstellung alternativer Texteingabegeräte und der Spracherkennung. Im übrigen kann das Programm auf dem PC sein, obwohl man gar kein OFFICE XP hat. DataFighter

RatingHad Spybot resident running while not connected to the net. It wanted to install once installation of OFFICE 2003 finished. It may log your input, but its not spyware. Eddie
RatingGets installed by other programs besides office. My XP laptop had it installed when I put on the new Delorme Street Atlas USA 2005. The "alternate input" in this case is the voice command to the mapping program. Anyway, be aware that other programs besides Office install this file. Phil
RatingThis file also takes control of com1 serial port cavu
