I know it monitors when you plug in headphones. When I kill it in Task Manager and plug in my headphones, I have to manually change my speaker settings.

Hogging up my CPU last night. Very Annoying. Couldn't use my machine. Windows XP Professional.

EAX does not need this file to work, I'm not sure if games require it, but for 95% of users ditch it and gain 5megs of memory.

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.

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.

Best practices for resolving cthelper issues

A clean and tidy computer is the key requirement for avoiding problems with cthelper. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the cthelper.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
