It manages a webcamera. You'll have whenever you have installed a software
Above tsnpstd3.exe was installed on my WinXP PC after I connected a newly bought webcam (in Thailand), with the name "PC WEBCAM - Real Digital Life", made in China. Apart from this .exe-file it also installed a DLL with the same name. Alos installed was the file "vsnpstd3.exe", a file version which is also going through the internet. The ini-file reads like it is necessary for TWAIN data sources. So, it seems, that both files are "harmless" and are needed for the Webcam to wo rk properly - at least that´s what I hope. Both files have been installed in Windows-folder and in Program Files Shar

13 May 2009. tsnpstd3.exe, vsnpstd3.exe & FixCamera.exe are all harmless files. They originate from a company called "Sonix". This company manufactures & programs the chips that control many types of webcam. If you have installed the relevent webcam, then these files will run on startup. Only worry if you haven't installed a webcam. Dave UK
