CSRSS.EXE Fake Claim That It Is A Virus

Have a new client who was previously contacted by a hacker who told her that her csrss.exe file as a known virus and she had to hire him to clean it.

This actually a required file for Windows 10 and while it *could* be a virus it is easy to determine if you are running a legit version by simply opening the task manager and checking if the file is located in the System32 directory.
