    CSRSS.EXE - Confusion

    Csrss.exe is the Microsoft client server runtime which generates worker threads for client requests. The confusion over csrss.exe comes from Trojans or viruses that use the same executable name (.exe) as that of csrss.

    Many spyware/malware programs use filenames of usual, non-malware programs.

    The legitimate csrss.exe is part of the Microsoft client server software and is a very important part of the system which should not be removed.

    One way to determine if csrss.exe is a legitimate file besides looking at the date modified is to right click on csrss.exe inside Task Manager and attempt to end process. Because csrss is a critical file, Microsoft should inform you with a message that csrss.exe is a critical system process and end it is not possible.

    If you do not receive this message when attempting to end the csrss.exe process, then it may indeed be a virus.
