Windows 7: I believe I have found a virus or two by accident

I was curious as Malwarebytes, MSE, and even ESET didn't find anything like this, while SUPERAntiSpyware found adware but not these, though I'm not too sure: but I brought up start task manager and looked under processes and found two that weren't under my user name (just so you know, under "users" it's just me), and after looking them up on google, learned that they might be trojans. They are: csrss.exe, and winlogon.exe. Well, that last one isn't really a trojan, but wasn't under my user name so I brought it up here just in case.

I don't want to get in trouble, as I need to do some accounting-related stuff soon n my comp., so I need to know if they are trojans or not, and if they are, how to get rid of them right away. Any ideas, and could there be more? (Again, Malwarebytes, MSE, SUPERAnti and ESET didn't pick this up)

Google is your friend.
csrss.exe

Client/Server Runtime Subsystem - Wikipedia, the free encyclopedia

So, no then, right? I thought I would check

Yeah, they are both good.
there are viruses that use names very very close to csrss and people confuse them for the real thing which might be why you read something confusing on the matter.

You should really put more trust into your security software. If they say you do not have an infection, it is highly likely you do not have an infection. Second guessing is unproductive and doom to failure.

Usually you can tell by the location of the process. E.g. the real csrss.exe has to be in C:\Windows\System32

Yup, its there. Thanks guys, problem's solved.

crss.exe and winlogon.exe are both valid system files, neither is a Trojan if both reside in System32.
