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.
