My NIS 2011 "Run Live Update" indication at 2052 today (UK time) was "1 day ago" so I did a manual Live Update. I was surprised to see the 5 updates downloaded and installed came to 86.57 MB. No restart was required. Just curious about the size. They seemed "run of the mill" definitions and never that big but one which I don't think i've seen before was "Web Protection Definitions (hub)" - is that the big one?
