Csrss.exe & winlogon.exe shown in 'process' of the Task Manager with no user name or from a cache. How can I remove or put an end to this process?

Csrss.exe is a knowledge trojen or spyware to invade the PC security

Hi Albert,

Csrss.exe, this is the part of the user mode of the subsystem Win32 (Win32.sys being the kernel-mode portion). CSRSS means client/server run-time Subsystem and is an essential subsystem that must run continuously. CSRSS is responsible for console windows, creating or deleting threads, and some parts of the 16-bit virtual MS-DOS environment.

Winlogon.exe is the part of Windows Login subsystem. This process is responsible for managing the security key sequence (by pressing Ctrl + Alt + Delete before you see the logon box), loading of user profiles, the locking system when a screensaver is running and check the activation key for the operating system.

I suggest you to run the Microsoft Safety Scanner and check if there is no virus.

Microsoft Safety Scanner: http://www.microsoft.com/security/scanner/en-us/default.aspx

Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again. The data files that are infected can be cleaned by removing the file completely, which means that there is a risk of data loss.

Let us know the status of the issue.

  • Csrss.exe file in the Task Manager without a user name or to the description

    I was told by a Yahoo tech, which was supposed to come back to me in my locked e-mail account, that it is a virus. I did some checking and found a response (from the forum) who said: if I'm trying to complete the process and get a warning window pop up, it's a legitimate file (I get the window). If I right click on it, nothing comes. Has verified the Virus, malware check, used the scanner Microsoft and even a (Speed up PC) supposed to get rid of this (if it is a virus), all come out clean. Yet, the guy from Yahoo (I called once again, argues that it is a virus. I'm confused, ideas?

    Hello

    Csrss.exe is a Windows file that is stored in the directory c:\windows\system32 which corresponds to the description of the file: "Client Server Runtime process.

    The csrss.exe file included with Microsoft Windows is not spyware, a Trojan or a virus. However, as any file on your computer, it can be damaged by a virus, worm or Trojan. Antivirus programs can detect and clean this file if it has been infected.

    It is not safe to remove csrss.exe processes from the Task Manager. Csrss.exe is a critical system process may not be withdrawn without causing problems with Windows in Task Manager.

  • Iexplore.exe process still running in the Task Manager

    I was see multiple iexplore.exe processes in the Task Manager when I'm not in IE, so to trouble shoot it I uninstalled IE, run several different scans/squared (which found nothing) and iexplore.exe is still appear in the Task Manager. I guess that it is some sort of virus since I uninstalled IE and it is always showing to run. No idea how to do the trick of it? I am running XP.

    IF IE 8 was present in the control panel > add or remove programs, then when you have uninstalled it from there, you have restored the previous version of Internet Explorer, in other words, IE 7.

    The best way to confirm this is to start IE and then click Help > topic.

    There is malware that disguises itself as iexplore.exe.  If you see iexplore.exe or Iexplore.exe in msconfig or in the Task Manager after Windows startup, but you did manually start Internet Explorer, you probably don't have a problem.
    What antivirus applications you scan with?

    If you haven't already done so, I suggest to do the following:

    Run a scan virus online with the eSet online scanner (may require a download if you are using a version of Internet Explorer)

    Download, install, update and run MalwareBytes AntiMalware (free)

    Download, install, update and run SUPERAntiSpyware

    You can uninstall all the latter after their use, if you wish.

    I need to be able to hide or to limit a summer in the Task Manager process.

  • When I open the Task Manager and select "Show processes from all users" there are 2 files virus csrss.exe?

    original title: virus csrss.exe?

    I use Vista Home Premium.  When I open the Task Manager and select "Show processes from all users" there are 2 files csrss.exe.  I learned that this indicates that I was infected by a virus.  Is this the case?

    Hi Julie,.

    Did you the latest changes on the system?

    Csrss.exe is Client/Server Runtime Subsystem.  All the Microsoft system has file csrss.exe running in the Task Manager, but it is likely to be infected by others. If it uses a lot of time processor and extremely abnormal in activities in the Task Manager, you can run a scan of the system security.

    You can read the following article to download the Microsoft Safety Scanner and perform a full scan on your computer.

  • in the Task Manager, processes is called xxfirefox.exe is - this legitimate?

    Upgrade to Firefox 9, when I look in the Task Manager, the name is XXFIREFOX.exe. Firefox has been hijacked or is the new name for the v4?

    The main Firefox process is always named firefox.exe in Windows 32-bit operating systems.

    I would be very suspicious of a process named XXFIREFOX.exe. My advice is to run a full scan with your anti-virus software, and who does not find a problem if doing a "search > for files and folders" for this executable.

  • SOLUTION EXPLORER. EXE must always run at the start of the TASK MANAGER after the LOGIN/WELCOME screen.

    Trying to restore the empty desktop icons by the recommendations, I have a white screen with a pointer after login and WELCOME screen.  CTRL-SHIFT-ESC gives me the TASK MANAGER. and I returned 'explorer.exe' I then the full desktop with white icons.  I need to do this every time I have start or restart the PC. I checked the regedit and the only entry to WINLOG, SHELL is "Explorer.exe" any ideas about a problem?  Thank you!

    Hi Eric1029,

    You can check if the following registry entries are correct.

    a. open the start menu, in the search bar type regedit, and then press ENTER.

    b. navigate to the following location and check the entries for "Shell" and "Userinit" on the right pane:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

    "Shell" ="Explorer.exe" (REG_SZ)

    'Userinit"="C:\WINDOWS\system32\userinit.exe '.

    c. also check if you have the correct permission for this registry key (winlogon)

    d. right-click and select permission. Make sure that at least with that you have group administrators, system and installer of confidence with full control and users group read permission.

    e. check if you are able to launch explorer.exe in the window running in the Task Manager.

    Important: The above method contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

    For more information about how to back up and restore the registry, follow the steps from the link below:

  • Windows 8 does not not log on screen, all black dekstop, explorer.exe, disc missing from the Task Manager

    Hey. I am a newbie in this forum. And I really like to make my PC more 'me' even though my parents and brother told me that my PC did not differ from how difficult. But, I still like my PC... ^ ^
    But my PC encountered a problem in my birthday (March 8, ehehe just FYI). Its a terrible birthday gift: (...) Oh, there. Its all started when I accidentally install a skin pack or win 7 in my PC 8 victory. There is nothing wrong with installing proggress except a notification which inform on win 7 Starter has not installed correctly. :( Well, I ignored, first. But after I have it reboot, my dekstop went all black but it still can open the Task Manager. And then I try the system restore. It did not work properly. The only thing made worse. Somehow, my "(le seul compte dans mon PC) DELETED account." In fact, the log on screen consist only of the ease of access and power button with backgorund optomistic. Where are the data of the user, I mean a place where we inserted the password? XC its make me super bad mood. And after some restoration system with various restore points, I restarted my PC in safe mode successfully. Yippie, its worked perfectly in safe mode. I created a new account in safe mode. I thought that my problem more but no. and the bad news is that there is only one user account (a new one) in the journal on the screen! It'll be better I have the new account very well work, but it didn't! The dekstop always all black with no taskbar and it's the same problem as the first.
    I am not really confusing. What should I do? Should I remove a skin pack safe mode? or reinstall win 8 in PC COUNTER? Or do something that you already know the guy?
    Help me. I am so irritated by this problem. In any case, I want to ask one last thing, you prefer something after me or just think it was a charitable organization? Well, I just want to know.

I need your response. :") SURE ME MY CRAZY MOM, IF SHE KNEW IF I AM WRONG IN MY PC AGAIN.

    Oh, there. The explorer.exe does not start in normal mode, but it works fine in safe mode. Also, I discovered that the disc is missing from the Task Manager. :) Help?

    Wish you a very happy birthday, Damaris.

    Of course, I can understand the situation you're in right now, and it's a shame. I will be happy to answer your query and try my best to offer my help as a gift for your birthday.

    Let me ask you;

    1. What happened when you tried the system restore?
    2. What was the last time that the computer worked well?
    3. What security software is installed on the computer?
    4. Remember to no particular change in the computer before the show?

    The issue may be due to any dispute of third party software, virus or any system or missing files / corruption. Let's try the methods below and check the status.

    Method 1: Since you are able to start the computer in safe mode without any mistake, I you suggest to start the computer in safe mode and then perform the clean boot to avoid software conflicts.

    Step 1: Start the computer in safe mode (as you are able to start the computer in safe mode with the steps you tried).

    Step 2: Perform the clean boot

    Method 2: Run Microsoft Safety Scanner

    The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

    Microsoft safety scanner

    Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

    Note: Data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

    Method 3: Run the tool File Checker system in case where any system files are missing or corrupted.

    System File Checker is a Windows utility that allows users to find corruptions in Windows system files and restore the damaged files.

    Enter in the right edge of the screen and then click on Search. Or, if you use a mouse, point to the corner bottom right of the screen, then click on Search.
