Is csrss.exe a trojan?

Hi Amzakil,

Welcome to the 7forums :)


You need to start command prompt as administrator (right click command prompt and choose 'run as administrator') to find the file in command prompt.

Winlogon.exe is a Microsoft application, it should be located in C:\Windows\system32. The conditions of winlogon.exe is the same.

I followed your instruction and here's the result:

"Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Users\Asus>dir /s csrss.exe
Volume in drive C is OS
Volume Serial Number is 24AF-7AFF
File Not Found

C:\Users\Asus>"

Does it mean malware because it connot be found in C:Windows\Systems32?

I found in the other website that it is normal when you check the Show processes from all users and find the file (csrss) you can find its user name and description and can click Properties or Open File Location and there it is located in C:\Windows\System32

But what about winlogon.exe? Are their conditions the same? Thanks!

You tried to look for it under the users directory.
