Lsass.exe - normalno ali virus?

Sem pogooglal kaj tale lsass.exe je in mi da dva odgovora.

Description:
lsass.exe is a system process of the Microsoft Windows security mechanisms. It specifically deals with local security and login policies. This program is important for the stable and secure running of your computer and should not be terminated.

Note: lsass.exe could also be a process which is registered as a trojan. This Trojan allows attackers to access your computer from remote locations, stealing passwords, Internet banking and personal data. It could also be a registered security risk and should be removed immediately.

Zdej pa mi na podlagi tega, da je NetLimiter zaznal, da mi sprejema kilobajte (cca 4,5kB na dan) oddaja jih pa ne, povejta a je virus al ni? Kateri protivirusni program trenutno najbolj priporočate?

Bodi pozoren na to ali je lsass.exe ali je isass.exe, ker če pišeš L z malo i pa z veliko zgledata isto(l I). In isass.exe je virus.
