Client server runtime process & csrss.exe

Question

Windows 8.1 64bit,  9/30/2014

i have 2 client server runtime process running, is it normal? when i click on them & chose open file location both show csrss.exe as source, so it should be normal?

so if open file location shows csrss.exe located in C:\Windows\System32 with both, then its normal?

Task Manger under Detail Tab i see 16 csrss.exe running & all are running under System, is that also normal?

Answer 1

in windows forum, one explained LogonUI.exe is running when user sees welcome screen & later before windows opens it gives the work over to Winlogin.exe

Answer 2

I have someone calling me on the phone to tell me this is enabled on my PC and is sending thousand's of reports to them. They want me to disable this, because it's a virus, I'm very sure it's not Microsoft. I am not doing what they want either, their phone number on caller ID is 1-786-272-1537 and the name is MarkWest Hydroc.
