tedder,
ZSSnp211.exe is a file often associated with Bigdog/Vimicro, who make various products, the most common being webcams. Although they mainly cater to the Chinese market, they're not exclusive to the area. I'm not 100% sure exactly what this particular file does, but I believe it is your webcam driver. It shouldn't be anything malicious. You can try disabling it, but it may cause your webcam to not function properly. That's about the best answer I can give you.
However, I'm fairly confident that you don't have anything to worry about. But if you wish, you may still post a HijackThis log.
