Any Possibility of It Being a Virus?

It is absolutely normal and is not any virus neither it provides access for viruses to attack. There could be multiple such processes running with similar names but there is nothing to worry about this as it is verified harmless. For verifying if the Client Server Runtime Process is real or not, right click it in the Task Manager and select “Open File Location”. You should be directed to C:\Windows\System32 that contains the csrss.exe file. We highly advice you not to believe in hoaxes and other fake news that claims it to be harmful or a virus. You can run an antivirus scan to check any infected files and then do the needful. If you are directed to any other file location after selecting “Open File location” then you may have a problem as many malwares disguise as csrss.exe and afterwards cause problems. It is better to run a system scan with your antivirus tool.
