Smss.exe is a valid Windows file (session manager). However, it is also the name of a trojan. Location of the file will be the difference.


First:
Let's make sure your file is the valid one (I believe it is)

Please submit the following file(s) to Jotti.org for analysis: http://virusscan.jotti.org/

C:\WINNT\system32\smss.exe


Be sure to post the results in this thread.


Second:
Reboot in Safe Mode* and run HiJackThis. <-- IMPORTANT

Check the following items in HijackThis.
(note: If any R* items do not appear in Safe Mode, re-run HiJackThis in Normal Mode and remove them after you finish removing these items.)
O4 - HKLM\..\Run: [Windows Sound Manager] SndMon16.exe
O4 - HKLM\..\RunServices: [Windows Sound Manager] SndMon16.exe
O4 - HKLM\..\RunOnce: [Windows Sound Manager] SndMon16.exe
O4 - HKCU\..\Run: [Windows Sound Manager] SndMon16.exe
O4 - HKCU\..\RunOnce: [Windows Sound Manager] SndMon16.exe


Close all windows except HijackThis and click Fix checked.


While still in Safe Mode*, delete the following: (you may need to show hidden files**)
(Files specified without a full path will be located in C:\Windows\ or C:\Windows\System32\)
E:\WINDOWS\System32\SndMon16.exe

*How to Boot into Safe mode: http://service1.symantec.com/SUPPORT/tsgen...001052409420406
**Show Hidden and System files and folders: http://www.xtra.co.nz/help/0,,4155-1916458,00.html

Also, uncheck the boxes for hiding known file extensions and hiding protected operating system files. We want to see it all. When we finish here, it would be a good idea to rehide the protected operating system files but leave the rest to be shown.

Reboot in normal mode

Run HiJackThis again and post a new log in this thread.


Last:
Please download SilentRunners from here:
http://www.silentrunners.org/Silent%20Runners.zip
Unzip it to the desktop and double-click on it.
If you get any kind of warning message about scripts, please choose to allow the script to run.
When the scan is finished, a message will pop up and a logfile will have been created on the desktop.
Please post the entire contents of this logfile for me to see.

GO ahead and delete smsss.exe -- it's bad and not a part of Windows.

ALso, you do not show an AntiVIrus -- just a firewall?

Last, check your ignore list in HiJackThis. Your log is extreme,y short and I would expect to see more.
