This file is not a core Windows file, but we don't recommend terminating it because it is a part of a process that provides tasks between installed software and sound card from Creative Labs. In other words, CTHELPER.EXE 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. In most of the cases, CTHELPER.EXE works in the C:\Windows folder and takes about 23,100 – 29,520 bytes of disc space.
In order to hide their own viruses, hackers are naming their processes the same as a legitimate Windows files. So, although cthelper.exe is a genuine process, its name can also be used for hiding serious threat, such as trojan, worm or rootkit.
