A day or two ago I was visiting a board elsewhere, and was rather startled to see ZA (free) pop up a program-access request for lsass.exe, which has never happened before. I know it's a valid Win component (or should be, anyway), so ok'd it without the "always" tag. I've since removed it from ZA's program list because it seemed so odd. Any idea what could have triggered this, and whether I should be concerned? It's my understanding that lsass is primarily involved with security and encryption functions, neither of which should have been relevant to the particular site. Thanks and best, Mike P.S. If another forum would be more appropriate for this, by all means feel free to move it, as usual.
