The Nvidia Control Panel Display Properties Extensions applet is installed by default along with drivers for Nvidia graphics chips. It implements the extra tabs of configuration information that appear when you enter the ""Display Properties"" section of the Control Panel. This should be considered effectively part of your graphics card drivers and left alone. 

If you want a detailed security rating about your NvCpl.dll (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!
