Okay sometimes when I'm seeding and leave my comp for a while and come back. Norton will have displayed a pop up that it is blocking lsass.exe. Now I know this is a windows service but I also heard that there is a virus by the same name. So far I always block the attempt but on Windows support they say that lsass is a pretty critical service. Anyone else experience this or know what I'm talking about and if I should keep blocking it?
