    This is the "Client/Server process" and an essential part of Microsoft Windows operating system. It is not unusual to have more than a single instance running concurrently but as certain virus/trojans can masquerade as this file, you should perform a system scan if in any doubt. The legitimate file resides in %SYSDIR%\csrss.exe. Any instance running from a different directory will almost certainly be malicious.
