Why are there such file names in Kaspersky Anti-Virus updates?

Question

Antivirus

A long time ago (about 5 years ago) the main Kaspersky databases were called basexxx.avc (now .kdc, but that's not important). xxx were 3 digits - from 000 to 999.

And it became very interesting to me - what will happen when there are more than 999 of them? My personal hypothesis was that there would be 4 digits - from 0000 to 9999 (in my opinion it is logical). But oddly enough, after 999, 99a, 99b, 99c, 99d, 99e, 99f, 9a0, ... went, in general, the transition to hexadecimal digits, but only after 999.

A strange scheme. But okay. Now it became interesting to me - what will happen when they reach fff. Again, my personal hypothesis was that since they do not want to switch to 4 digits, it will probably be ffg, ffh ... ffz and so on. However, again, this did not happen. Instead, 00a, 00b, 10a, 15a appeared ... in general, the same hexadecimal numbers, but already everywhere, and not after 999.

Now I'm actually wondering - after all the numbers from 000 to fff are still filled - what will happen next? I'm afraid to even guess :D

Answer 1

I suppose you think about this more than the one who chooses the way these bases are numbered)

Answer 2

will use the remaining letters after F

Answer 3

Then there will be a new database format :) and everything will change.
