Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

Camilo Quemedigas Medaigual Windows NT4/2000/XP/2003 only. It verifies the validity of user logons to your PC/Server (in technical jargon : it generates the process that is responsible for authenticating users for the Winlogon service). An integral part of the operating system, leave alone provided that its full path as shown is either C:\WinNT\System32\LSASS.exe (Windows 2000) or C:\Windows\System32\LSASS.exe (Windows XP/2003). If the path is anything else then you may have a virus.
Darren O'Brien Possibly a virus as the real one is Lsass.exe  See also: Link
Barak G. I started to investigate what I have in the computer since I saw a non stop stream of information going out and coming in even when all progs were closed. No program I have could identify it (yet).
DaveMc If you end task it, it auto restarts. LSSAS is malware, meant to be confused with the legitimate LSASS, pay attention!
On my system it (lssas.exe) locks up port 21 with a "Listening" status upon boot.
MagiDrum adds pop up ads related to the adware.easysearch browser hijacker which is a variant of the coolwebsearch and about:search hijacker. Very annoying and hard to get rid of!  See also: Link
Phil I can not get on internet when it is running. When I "kill" it I can acces the internet.
BeerLover Without closing lssas.exe I can't run a ftp-server. I think it uses the same port 21
