How do i delete Csrss.exe?

I ran a malwarebyte's anit-malware scan and i showed csrss.exe as a virus. i know that your if you delete it, your computer will get the blue screen of death. However, in the processes, there are two csrss.exe. The first one is located in system32 and the other is in the Appdata/local/temp folder. i tried to delete it but it would just reappear again. Does anyone know a way to delete this virus?
