Is csrss.exe a virus, spyware or a trojan?

What is it?
csrss.exe - Client/Server Runtime Server Subsystem

What does it do?
This is the user-mode portion of the Win32 subsystem (with Win32.sys being the kernel-mode portion). Csrss stands for client/server run-time subsystem and is an essential subsystem that must be running at all times. Csrss is responsible for console windows, creating and/or deleting threads, and some parts of the 16-bit virtual MS-DOS environment.

You will not be able to end this through task manager!
