How big can the accumulative database update zip file reach in the future?, Manual update of Kaspersky Internet Security or Antivirus Options

[Humanpix]

Those who has to manually update Kaspersky Internet Security or Antivirus will wonder how big can the accumulative database update zip file reach in the future? It used to be just around 7 MB at KAV version 5. Now it's around 19 MB.

I guess you need to be asking those that create the malware. While we are in a world using definitions to help keep known malware at bay, it will not stop growing.

Maybe in a years time it will becaome 50MB or even 100MB.
It indeed depends on the malware writers

you have to remember that a database isn't just a book with signatures for malware, it also holds algorithms for packers (some are modules of the program eg zip but some are built in to the engine, for example a lot of runtime packers), the more packers the bigger the database, then there's disinfection algorithms, generic signatures, some heuristics (v7 has a new heuristics engine which is a separate module, ~1MB on it's own), web anti-virus streaming signatures (didn't exist in v5), registry monitor keys etc.
