82,10MB Norton SDS Definitions update after 541,74KB failed ?

So i was among the few that had difficulties updating last night (see that thread).

This morning i started LiveUpdate and on 4 updates, 3 succeeded and 1 failed. The failed update was the Norton SDS Definitions X64 and was only 541,74KB. So i started LiveUpdate again and this time the update succeeded but was 82,10MB .

I've checked on my other computer (same OS, same version of Norton Security) and the update completed and was only 541,74KB. There is no 82,10MB update.

So I'm just curious as how from a small update of less than a megabytes the same update can weight more than 80MB ?

My guess is that as it failed to update the definitions it downloaded the whole database again, but i just wanted to have your opinion.

I use Norton Security 22.8.1.14 on Windows 10 AU.

Here are some screenshots:

Thanks a lot
