Hi, I found a odd behavior in update version 1.917. My NOD was updated successfully from 1.916 to 1.917. The problem is that I checked again some hours late to check if is available 1.918 or a more recent update. NOD32 started downloading engine2.nup again and updated from 1.917 to 1.917, in others words, NOD32 downloaded the same update again. This problem occurs with the server. And something veru urgent. Recently I noted that the engine2.nup file that has the u3.eset.com server is about 57 KB and the engine2.nup that has the u2a.eset.com is about 67 KB!!!!! And is the same file and the same update version. What happend!!??
