I am running ESET NOD 4.0.424.0 on two machines, a desktop and a laptop. Both machines are running Windows XP SP 3. The desktop has updated the virus definitions automatically and correctly to level 5951 (20110314) as of 8:35am ET. The laptop refuses to update, despite repeated manual attempts, all that comes back is "Update is not necessary - the installed virus signature database is current." The laptop definitions level is stuck at 5945 (20110311). I have rebooted the laptop twice with no luck. Should I just wait to see if the laptop updates when definition level 5952 comes out, likely later today?
