Process name: Windows NT Session Manager
Product: Windows
Company: Microsoft
File: smss.exe
Security Rating:

This is the session manager subsystem, which is responsible for starting the user session. This process is initiated by the system thread and is responsible for various activities, including launching the Winlogon and Win32 (Csrss.exe) processes and setting system variables. After it has launched these processes, it waits for either Winlogon or Csrss to end. If this happens "normally," the system shuts down; if it happens unexpectedly, Smss.exe causes the system to stop responding (hang).

Note: The smss.exe file is located in the folder C:\Windows\System32. In other cases, smss.exe is a virus, spyware, trojan or worm! Check this with Security Task Manager.

Dark Prophet It's a normal windows file, but the dang thing seems to get corrupted along with csrss.exe all the dang time. Not sure how to clean up. v.v
found it inside my windows directory and system32 the one in windows directory was smaller I have deleted it and everthing seems to work,
Telangana Reddy Obviously this is a windows subsystem file but may be a virus with a combination of other processes that appear in the taskmanager
Mufti Mahmud Not a Virus
Val A large number of spyware and trojan programs use a version of this file and the csrss.exe, both created in the %windir% (NOT %windir/system) to contact websites and irc to download programs and give outside access to your computer.
John Session Manager Subsystem,Application that is used to start, manage, and delete user sessions or client sessions under Terminal Server. is NOT a security risk
CJ I removed it from a client pc and had NO problems rebooting. File was in the sys32 directory too.
DataFighter Die smss.exe ist der Sitzungsmanager. (Session Manager Subsystem) Dieser steht als erstes Subsystem da, und startet die darüberliegenden Subsysteme und Dienste.
EvilGonzo Die Datei an sich ist völlig harmlos. Wird für Netzwerkverbindungen benötigt. Einige Trojaner nutzen Lücken dieses Progs, aber dafür gibts ja AV-Progs.
smss.exe, if located in system32, is LEGITIMATE AND NOT A VIRUS! If located somewhere else, and taking 100% cpu etc, it's a virus that just happens to use the same name, in an attempt to trick you! DUH
MAURICE IT MAY HAVE CAUSED MY SYSTEM TO CONSTANTLY HANG. ESPECIALLY WHEN ONLINE.
Piet Just read the note about this file above. If it is not in the c:\Windiws\System32 folder, it is a trojan. Go to safe mode, and simply delete it.

Richard Trend Officescan recently picked this file up as being infected by BKDR_AGENT.CZ by its real time scanner - but a full scan of c:\ reports no infected files. I one evenening between 2am and 5 am trend detected it as a virus BKDR_AGENT.CZ every minute - still looking into problem. Could be nothing or could carry a high damage risk like other variants of BKDR_AGENT
Tom smss.exe seems to be hard to delete adware (found in the windows file not system 32). Basicly a trick as it is a shared name and the process may not be stopped as it trickes windows into making it seem as a critial component. It may be deleted by renaming it rebooting and deleating the renamed file.
Paul I got smss.exe on my sys 5 times including sys32=45k/smss inc:\windows\=48k/ 1 in prefetch=30k/ 1 in sp1 files/i386=45k and 1 in c:\windows\software distribution\download\=50k i take it this is not good!! anyideas?

tony its a system file
loopthedanza not dangerous
666 - diese Wahrheit This isn't a virus. If you've installed the service pack, that file automatically gets installed with your system, no biggy. Smss stands for Session Manager SubSystem. In other words, this program is responsible for controlling sessions on your computer, which will help to stable and secure your computer. It's a critical system process, which means taskmanager can't stop it.
Mike Van got it from Dhakz.cjb.net It IS a Virus BackDoor type and it shuts off my nortons. If it wasnt for my firewall , I'd never of known. Only Trend Micro online scanner found it and still cant delete it
giel if located c:\windows\system32 then ok, if not.....sneaky they have the same names...they all should be named vires....lol
crux can also be in windows/servicepackfiles/i386 and in most cases is not dangerous
It can be dangerous. If it's not in windows/system32, delete it. If it's in system32 but uses an abnormal amount of system resources, replace it from the file on a windows boot disk (for your version of windows, of course)
micke irc client, some french Warez channel. Don´t know if it made any harm. Was in c:\winNT\security\database and in registry.
Danh A lot of viruses/trojans try to create files that have the same names as Windows' crucial files. Same goes for SMSS.EXE. If this file stays in the system32 or system folder of the Windows directory then it is a critical system process and should not be deleted (you cannot end its process). Otherwise, if it lies elsewhere and consumes a large amount of CPU resources then it is definitely a virus/trojan and should simply be deleted (in Safe Mode or Real Dos Mode). It can also be detected by HouseCall online virus scanner. Use the link below to launch HouseCall.  See also: Link

Trev If this is not some kind of Virus/Trojan, then why are so many people having this problem, non of you guys have addressed that yet that think this is a normal file.

beees the entry i found on my system with hijack this is REG:system.ini: Shell=Explorer.exe smss.exe - and seems not to be the "Windows Session Manager Subsystem" process since this one is also being (positively) identified by hijack this and is running under .../windows/system32 - where it is supposed to be running. i suppose it s not a normal process
Jake system files are crucial for the system processes of your comp - but - some viruses will pretend to be a system file so they cannot be detected - at the moment, my current smss.exe is running at over 500mb (which isn't good - it increases like a page file).

Tonyk compare the two versions, the one in system32 is legit, the one in system is not, it is probably a keyboard logger and should be deleted in safe mode. Counter spy blocked this application when it was trying to load into the startup registry, as the file is blocked it could not be scanned by the malware scan. McAfee latest updates did not find anything wrong, may be because it was blocked. So if it is in system delete it, if it is system32 then compare it to original. Use Windows utility sfc.exe
Logic Several versions, several situations alone determine status of file. All are conditional. In specific locations as described above, is requisite system file excepting particular circumstances where modified by malicious software and displaying particular excessive behavior. In locations other than typical, as specified above, it is malicious software. 2000 Server sp4 uses version with size 312k-other systems differ perhaps in native normal file size.
Mr B. New feature on Zonealarm detects some programs trying to use it. Did not monitor before new version so programs accessed it then, so it should still be OK now. PC does not have a virus or a worm.  See also: Link
Big Doc Lou a System file - pay attention people, if it is smss.exe and located in the system32 dir, it should be ok. Any other variation on the name or location, THAT file is bad.

Alec There is a ligitimate executable named smss.exe without which Windows will not work. People on here sayin 'it made my system go slow' are either referencing a different application masqurading as the ligitimate file, have peculiar problems which they are attributing to the file or are just confused. The risk here is that you may see a file named smss.exe running and believe it is the one which does need to run, when in reality you are looking at a virus. A good way to check is, if you are running more than one of these you may have a problem.
R3DBALL If not found in system32 then probably a virus. I watched this thing which was located in the windows directory quickly open regedit and then close it again. Only virii does that. This program had also set up a UDP on port 1076. It was not in the winlogon hirachy and ran off of internet explorer. Only remove if you can verify it is not the real smss.
Daron I had the virus! I had c:\windows\SMSS.exe and c:\windows\system32\SMSS.exe. Deleted BOGUS c:\windows\smss.exe and problems went away.
If smss.exe runs from a diffrent directory than system32\ (mine ran from system\) IT'S A TROJAN VIRUS! But be aware! Do not under any circumstances delete the MS systemfile system32\smss.exe - that's not a virus. Read the note in the top of this page!
Baloney I found this in a folder named 'WinSecurity' in Windows. It suddenly appeared after a browsing session and i isolated the time/date it arrived. Taking the advice of 'if its not in System32 file delete it' I deleted the whole folder. it also had services.exe and other malware programs in there
Ashley My AVG anti virus detects this file as a VIRUS, but for some reason will not get rid of it. It is very frustrating to say the least
Smss and lsass and csrss are Normal Files ** When they are located in the system32 directory **. If they are in the root Window folder They are SPYWARE. If you want to nat get infected with these files in the future, Here's What to do. Reboot in safe mode, go to your windows directory and locate the offending file. copy a version(Ms Certified) of that file from windows\servicepackfiles\i386 to your windows directory and write-protect them. By the way most spyware programs have another one unnamed that re-creates the offending files and makes them hard to get rid of.
xobkcah This file is not a virus! is a cool process that helps windows to run well , lol
look at the date it was created, if after windows install or update and is in windows system not sys32 then it is a virus. mine was installed by a bogus key gen (yea i know) and ever since 1/26/06 it attempts to shut down NIS 2005. i will rename and delete....not in sys32!
