PCgeek		isass.exe with an small caps L is a vital windows process and nt a virus. However viruses go under the name Isass.exe(Note this is an I not L) so they appear as vital windows process and not a virus. 0 1 Report Abuse
Dale		I made the mistake of deleting it from my registry thinking it was the virus instead of the virus being inside the thread. Now I realize that lsass is a needed component. So far all that I have noticed is that I can\'t search my C: drive. Anyone know where to download a clean copy of lsass since my laptop didn\'t come with an installation CD. 0 0 Report Abuse

Koko		lsass.exe Command: C:\\Windows\\lsass.exe Description: Added by the W32/Tilebot-IU worm and IRC backdoor. This infection should not be confused with the legitimate C:\\Windows\\System32\\lsass.exe file. W32/Tilebot-IU spreads to other network computers by exploiting common buffer overflow vulnerabilities, including RealVNC (CVE-2006-2369) and by copying itself to network shares protected by weak passwords.  More information 0 0 Report Abuse
Jon K.		Without it,your system will not run. Malware attacks its vulnerabilities, which is why everyone thinks it\'s malware. Scanners only display lsass.exe being infected, but it\'s a thread inside the process that\'s the malware. 0 0 Report Abuse
