_zope_app_container_contained.pyd is a process file created out of the Python programming language. It can be found on websites that run on the Zope application server.
The Zope application server is a software framework used to house various applications, often for creating websites. You may have its process file on your computer because you visited a site or a page that runs on Zope. The file in itself is not harmful.
If you are getting error messages about this file, however, it may be possible that it is damaged or out of date. It could also be a virus or Trojan file, disguising itself as one of Zope’s processes.
The only way to know for sure–and fix it if it needs to be fixed–is to run a registry cleaner (unless you want to pay a PC technician). You can get a free registry scan with ZookaWare PC Cleaner to determine what the problem is.
