    "lsass.exe" is the Local Security Authentication Server. It verifies the validity of user logons to your PC/Server. It generates the process responsible for authenticating users for the Winlogon service. This process is performed by using authentication packages such as the default Msgina.dll. If authentication is successful, Lsass generates the user's access token, which is used to launch the initial shell. Other processes that the user initiates inherit this token. More info

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

    Virus with same name:
    W32.Nimos.Worm - Symantec Corporation
    W32.Sasser.E.Worm (Lsasss.exe) - McAfee
    W32.HLLW.Lovgate.C@mm - Symantec Corporation
