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.

 

Bad Memory leak related to a csrss process, system process and possible CCC.exe

CCC is the ati video card software. Very large program. Could be updating software in background, and installing software.

csrss could be a virus. It depends where it is located, It is easy to misidentify a process as a virus, you have to look at it very carefully (check spelling, spaces, file type ect)

Read up on the csrss.exe to figure out if it is a virus or a legitimate process
