All comments about cthelper.exe:
should be some stuff the soundblaster needs
Background task that works as a plug-in manager for Creative drivers. It helps the third party manufacturers to produce drivers, add-on features, and fixes that will integrate with a tighter fit with Creative sound drivers and utilities. Ebula
Background task that works as a plug-in manager for Creative drivers. Sema4
It hogs all of the CPU. Search to see if its in a windows system folder. Ebula came up on my firewall
As it appears it is harmless, I have a seen a bug that uses this name with all cap letters running from the root directory. Normally this file allows for the third party effects and sound distribution over the creative labs soundblaster 24 bit sound systems. If you do not play games or record your own digital music. You should be able to kill this process without effecting your performance. Magus

it is only a waste of resoures zeek
it was using 99% of my CPU jason
is this thing supposed to be taking up 99% of my cpu useage? :/ deus
The only harm it has caused for me is somehow managing to use about 90% of my processors time.
not sure if it causes problems but takes up the entirety of my cpu capacity davegb10
it's annoying
Not normally dangerous, but sometimes can have a bad memory leak Matt
This file doesn't listen on any ports... so its not dangerous... It also doesn't appear to send out information. Mike Denzil

Yes it is part of Creative Snd Blaster; should only take up 0-1%of CPU usage(otherwise u have other issues); not essential unless u' use 5.1+ sound in advance gaming or media Yjrampage
For some strange reason one of my development softwares (Windev) won't run while this file is memory. Nor will the setup files run for reinstall. Other than that, no ill effects. Responds fine to end task. Ben
This file is a real pain as it is always hogging memory up to 98% of available resources, seems to be particularly bad after running demo versions of new games software, ie : MOHPA MP demo. Dave T

Part of my sound card, but is it necessary? Rob
Seems like it loads with a registry entry about WinDVD - doesnt sound good to me as it looks like Spyware Buck
cthelper.exe is present on the installation Audigy 2ZS CD-ROM from Creative and the file is present in 3 directories when installed C:\windows\system C:\Program files\Creative\SBAudigy2ZS\Program\VxD\common and C:\Program files\Creative\SBAudigy2ZS\Program\WDM\common and is connected to CtSpkHlp.dll What it does I have no idea but certainly is not dangerous or Creative wouldn't put it on their installation disk.

It helps with Sound Related Problems. Game Patches or Add-On's for Music Software might rely on this. But as far as i know (wich is probably not very far), nobody ever used this stuff. Chistian Voigt
cthelper.exe is installed with Creative Labs Soundblaster Devices. It's purpose is to aid 3rd party developers create plugins/software for the card. In this way it is a non-essential system process and can be removed from the task-bar/startup (run - msconfig). If you play games I would keep it enabled, pherhaps lower its priority.  See also: Link Michiel NL

CT Helper is in fact a tool to Enable Soundblaster Live and Audigy Cards to make use of the surround functions of WinDVD (a DVD Player Software from Intervideo). If you enable 4 Speaker mode in Creative Surround Mixer, you wont be able to use 4 Speaker Surround Mode in WinDVD unless you're running CTHelper.exe. If you dont need surround, you can disable it in the registry. Bjoern
takes up 99 percent of cpu Scott
dont even dream about running this with hl2
I go to processes and click on it and click 'end process' and i click yes but it stays there! Kyle
I find most times this program is consuming my computer is in an idle state but since I usesoundblaster for its firewire input for my audio interface I am worried about deleting it. I might need that function in the future. Plug-ins are almost essential in somespacific software and these programs will not fuction as efficiently without them.SOLUTION; I just end task in task manager. Rob V
Creative Soundblaster, Audigy, Audigy 2, ZS background driver. Should only use 0 - 1% of cpu & less than 2000k (2mb) of memory. Not critical to leave it on but it may improve performance if playing sound intensive programs (gaming as well.) If cpu usage is more than 5% you may have a conflict / memory leak and should find a fix for it. Other than that its better to just leave it on. Dev
Creative's file, may be desactivated
Its harmless, if it causes trouble on your pc, try to config it better XtremeS
You can get rid of it, it's useless even if you play with the ultimate games. Use msconfig to stop it loading at start. ßodincus
This apparently enables me to set the surround sound settings. Without it I actually can't get any EAX and high-quality sounds. I suspect CTHelper means Creative Taskbar Helper, in which case makes sense, as the Taskbar is the center of my SB Audigy's processing program. It doesn't have to run, but it lets me change my audio settings, and stores it. I guess CTHelper runs the settings when the bar isn't activated. MikeMcLarenF1
CTHELPER.EXE is a creative file. I've got a worm (c:\windows\system32\agbqfp.exe) and can't delete it, because it is used by CTHELPER.EXE. CTHELPER.EXE wont end when i click end process. Aksel
Should i kill it? and if yes how?

Because they drop a Global kernel level hook and kernel level keyboard (keylogger) hook in with installshield (which seeks RPC locator service immediately) all the other more obvious backdoors are decoys for us to find. Having a kernel level rootkit in they own your box. The only way to remove it is repartition and reformat. You will not find it. l0thar

I think its best to disable this item, as it records ur mouse movements n keystrokes which is detected by ZoneAlarm and its v dangerous if u were to goto internet transactions and records ur ID or PIN number without u knowing it.. redlightdistrix
This files has been idenitfied as a key logger on my computer. My firewall caught it. Be carefull with this file WC
This program frequently froze my operating system. Cthelper.exe especially doesn’t like pendrives and digital cameras attached to USB port. The error window appears and system hangs. Agano
It interfered with other software on my system - ie it caused After Effects to shut down and may have been interfering with Avid Xpress Phil
was sending packets for me and would not end process geddoe
Sometimes usues 100% of cpu cycles. Newer versions seem to be ok.
Name can be co-opted by W32/Rbot-XB worm. You will be unable to end this process via task manager if this is true.  See also: Link Flash
it may be part of Creative files, but why does it have to access the internet on windows load? I am running Panda Antivirus and everytime I start my computer, it says this file is trying to access the internet. I have it blocked from internet but leave it running in processes. Budreaux
Time by time it uses nearly 100% of my CPU. I have to shut it down with task manager when this problem occures in order to be able to work at normal speed! When I shut it down, everything works properly. oldves
I have Audigy 2 ZS and mine CTHELPER.EXE is not in C:\Windows\System folder it's in \System32 folder and doesn't take 2 mb, it takes 4,5 mb of memory. Is something wrong?
Lags my computer. Gets locked up and unresponcive. Zap
The reason i became aware of this file is because at every startup the Dr Watson Post Mortem Debugger is launched by it, i.e. cthelper is unable to launch itself... apparently it is not necessary unless your are using 4 speakers or windvd or both, so to avoid this debugger at every startup i have disabled cthelper at startup... fingers crossed! dbenno

SB platinum file Lostsoul
not a problem unless openoffice.org's error reporting has been forcibly turned off by micro$oft, at which point, Lsass.exe and cthelper.exe share about 98% of the CPU.. Why?! I have absolutely NO idea. Micro$oft does hate opensource, and OO.o is Opensource... Deviros
creative driver, absolutely harmless if its the one from the creative drivers. mine never seems to use any cpu whatsoever. after extensive monitoring of this file. although EAX, EAX2HD seems to not work when I disable/stop this file. seems pretty harmless to me monkboy
Not much but just installed sound blaster Alan
i removed cthelper from "run" and then sampling with soundcard goes only up to 6000 Hz, I thoght my card is out of order, but registering again cthelper in autorun and the audigy samples properly holg
Has replicated over LAN, tcpdump says it tries to scan internal shares and open an irc port. Spyware 4 sure. Mario

cthelper.exe is installed with Creative Labs Soundblaster Devices. It's purpose is to aid 3rd party developers create plugins/software for the card. In this way it is a non-essential system process and can be removed from the task-bar/startup. If you do not have a creative labs device then you may have a virus or a trojan. If you are having problems with this file your system may not have the required recources for it to run. it is not system essential but will disable 3rd party plugins for the creative labs devices. if it is hogging recources then consider scanning and removing it.

A lot of people report stuff using a lot of CPU usage, its normally a defect in the installation of the hardware. Try re-installing it. Also, check to see if your system meets it's system requirements, if it doesn't you can suffer extreme penalties such as the CPU usage. Not all users will find that it takes a lot of CPU usage, This should be enabled for the best performance in any of your Creative products (mainly Sound Blaster). Jason Strese
I have an e-mu 0404 soundcard, which i use for sound production. I know that creative now owns e-mu and uses some of the same parts in both brands, but when i was using linux it would always detect a soundblaster card the for which the drivers are incompatible. (E-mu drivers have no official support from Linux or windows so neither one ever detects them right.) I was just wondering if cthelper is needed to run the e-mu drivers and patch mix software (1 each 1/4" L-R stereo outs and ins are the only i/o devices i use and i don't play any video games on my machine or have any use for surround dicky mkeatballz

I can't end the process. This may sound odd as Creative is supposed to be reputable, but I reinstalled my sound card drivers directly from their website on a fresh factory settings PC and immediately got a virus. This was about 3 weeks ago.  See also: Link Susan
It's Creative's part, it came to me only with SB install. Uses ~1% of CPU resources. (SB Live! 5.1 Digital, WinXPSP2) laji
has a tendancy to take over the CPU causing a serious slowdown, it does this if you change the sound settings (like from 2 to 5.1 speakers)

Pshhh...Close this. It comes with Creative Drivers/Software, but it's only the help program. It's hogging your memory.
It is required for plug-ins for your soundblaster card. Meaning 5.1 surround sound won't work with out it, but you don't need it otherwise. Jet

It was installed with the IRC client Irssi Client and was located in the program files folder for this program. I do not have a creative card or anything creative so it isn't that.

Hi, I suspect there is a trojan using CTHelper's handle. I had a problem last week with CThelper, "CThelper Apollo" was on my computer and AVG had to clean my computer up after it had been slowing down for weeks. All other processes eventually ground to a halt. They seemed to use Malwarebytes to clean my desktop up. Derek.W

Software installed by the Creative soundcard driver
It is part of Creative files for the Audigy series of soundcards. Reportedly if you disable of remove the file, the only adverse effect is that the soundcard doesn't shut down all the speakers when you plug in headphones in a front jack. It can be a resource hog so disabling it from startup is advised. Troggster
can be disabled without any apparent effect. might cause as yet undiscovered problems though. awesome knowledge man.
Agree that it's Creative's file. I'm running a notebook Audigy ZS on an XP MCE machine. Could be a culprit behind some BSoD. Does not play well with others as it might cause crashes if two MIDI programs are open at the same time. Check for memory leaks, you will hear popping in the audio before as this happens. Rec using a mem defrag if switching SoundFonts as the memory leaks seems real. Creative still hasn't fixed it, or isn't aware this is happening. Chris
I just reinstalled my OS (Win XP Pro) so it can't be infected with anything yet. Also, I installed the drivers for Creative SoundBlaster Audigy from Creative Labs. It makes perfect sense that "ctfmon" is a startup app that the SoundBlaster audio card needs. snoofy10
