This so-called dynamic link library (DLL) contains all the functions that have been transferred to a separate file. These transferred functions are available not only to this particular program, but can also be used by other applications. The program executes in the background, and can only be terminated using Windows Task Manager. It is no part of Microsoft Windows. The file does not contain any exact product information, as would normally be expected today. It also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. For this service - unlike Windows' own system services - there is no good description available. CmdLineExt03.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 78% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.

A CmdLineExt03.dll file has a 82% certainty of being dangerous if it is found in a subdirectory of "C:\Users\USERNAME". In this case, the file size is usually 90,112 bytes. The CmdLineExt03 file is not part of the Windows operating system. The file also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. This process does not appear as a visible window, but only in Task Manager. The CmdLineExt03 file does not supply any version information or other description. There is no concrete documentation available for this service.

If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves CmdLineExt03.dll. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.

Seems to come from games - and perhaps it has som kind of spy-attitude. Solution is to run "regsvr32 /u cmdlineext03.dll" and then rename it. (further information...)
Hacker process... somehow gets on your system through the use of games... or so it seems. Delete it. (further information...)
runs from temp directory i think its not a friendly programm ;)
This file is part of some copy protections that come with games, and also leaves a massive hole in several ports on your system. Game may not run with it in quarantine, reinstall will fix game if need be.
while I was playing with viruses one made it so I couldn't right click on exes, using ShellExView I disabled it and I can right click again!
