Apparently a lot more that you idiots do
i think it is an aplication that asks for access to the internet to find cd album information.
Used by Creative Zen Mp3 player as detector
Comes with Creative sound cards (CD-detect?)
As far as I know, it's just a detector for Creative MP3 players. You plug one in, this detects it.
It gets installed onto your computer when you install something from Creative - ie your mp3 player.
something to do with creative mediasource
Auto-detect and play a DVD when using a Creative Soundblaster Audigy2 soundcard. Uses about 2.2 MB of memory. Disable it by heading to the MediaSource DVD Audio Player, selecting Tools, then uncheck the Auto Start box. It should not start up automatically again

Best practices for resolving CTDetect issues

A clean and tidy computer is the key requirement for avoiding problems with CTDetect. 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 repairing of your installation or, for Windows 8 and later versions, 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 CTDetect.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.
