task manager unknown processes...trojans?

Hello
Task manager I have several processes listed with nothing showing for them in the des. column. They show nothing under right click properties. I am unable to end the process for them.
I have ran malwarebytes scan with no threat detected.
anything to worry about? If so how should I end them or what should I do with these? They are as follows...
csrss.exe
nvvsvc.exe
nvxdsyn.exe
winlogon.exe

Those appear to me like normal Windows and NVIDIA processes. But I have the perfect solution for you

Process Explorer + VirusTotal (to check all processes with 50+ AV's)

Also you should know that when you start Task Manager, it's started as Standard User (if you have UAC enabled which is enabled by default in Windows 7), so you won't be able to see all processes or all details for all processes until you restart it as Administrator. Or click the button in Task Manager that says "Show processes from all users"

csrss.exe and winlogon.exe are critical system processes that Windows cannot function without. nvvsvc.exe and nvxdsyn.exe are NVIDIA processes.

With UAC active, the default configuration, even when you are logged in with an admin account, you really only have the rights of a limited user. Task manager and similar utilities run under your user account are are thus restricted in regard to what information they access. Accessing the description and some other information of some processes can only be done with an elevated account. Also be aware that some legitimate processes may not have manufacturer, description, and some other information encoded in the exe. There is nothing that you can do about this.

Detection of malicious processes is very difficult with only Task Manager. The authors of such software are too clever for that. Process Explorer will help, but only somewhat.

FYI I've described in the Tutorial what to look out for and things that might be more suspicious, and how to verify signatures etc. For suspicious processes you can also activate the lower pane to do a Virustotal check of all DLL files a process is using.
