Lsass.exe Is not a virus , it is the service program of Windows. Local Security Authority Subsystem Service (LSASS) provides an interface for managing local security, domain authentication, and Active Directory processes. It handles authentication for the client and for the server. It also contains features that are used to support Active Directory utilities.
This program is vulnerable to virus SASSER. Apparently, you have picked up it.
Update the Windows on a site microsoft.
It is necessary to establish the following:

The update removes the vulnerability by modifying the way that LSASS processes the specially crafted LDAP  message.

"Virus MlourdesHReloaded II ha atakdo esta computadora"
"Virus 100% Méxicano, no es muy peligroso que digamos"
"Pero tu has sido el rival más débil ¡Adios!"
"Saludos a Ana Paty de Sinaloa y a Gedzac Labs"
"Espero y se hallan pasado una feliz Navidad y un próspero año nuevo"
"Feliz 2004 para todos"
"Para mayor información enviar un e-mail a tips@esmas.com"
