I have never had any issues with NOD32 updating each day when I boot, in fact it is the first AV which I ever trusted to get updates automatically. Over the last week or so I have noticed there are days which I have to check myself as I knew there was an update NOD didn't do this automatically when I booted. Other days NOD has no problem. Today NOD didn't update - I checked manually before actual launching my browser. Reported I didn't need any updates, came to this forum and noted one update was there from yesterday (I was offline when this was released) I hit 'update now' again got sever error - tried again and NOD updated. I haven't any other issues with updates for my software and this is the first 'hit and miss' with NOD somedays perfect whilst others I don't get any after booting or I am told I don't need any when I actually do. I can still update but just not depend on NOD on auto as I used to do. I wondered if the fact Microsoft call home every so often would affect NOD's initial connection with the update? NOD used to update without me even having to check to make sure.
