Its part of the internal webcam driver suite on Lenovo 3000 N100 notebooks, made by Sonix Technology of Taiwan. Can be verified if one looks at the driver for the webcam entry in Device Manager under XP. See Device Manager (XP) for "USB 2.0 PC Camera (SN9C201)

It came with the latest software for the Celectron USB Microscope. As per description above, mine is 262,144 & there is an icon in the task bar next to the clock, and if I right-click and select "Exit" the process tsnp2std.exe closes and is gone. It IS important for the operation of my "webcam" (actually microscope) so I certainly wouldn't delete it or consider it even 1% dangerous!

Came with my KROSS webcam. System scans do not quarantine it. This is a hardware related file used with cameras or webcams. Sonix is also a maker of this software program. This file will be found in your system startup list. This software is considered safe, and is not virus or spyware related software.
It came as part ofmy Soni webcam installation package

Best practices for resolving tsnp2std issues

A clean and tidy computer is the key requirement for avoiding problems with tsnp2std. 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 tsnp2std.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.
