Hello Steve, > As for "removing" a 3rd party signature when official ones block it, > well... overall... it wouldn't really be a good idea. Why ? Clamav official signatures + all 3rd party signatures needs a lot of system RAM. Optimizing our signatures to scan faster and use less RAM should

Hello, > Out of interest, what does it matter? The question of Axb is interesting. Such option could be used to remove signatures from 3rd party when detection is done with official signatures from Clamav. We do not need 4 different signatures in RAM to get the same sample detection. --

Out of interest, what does it matter? Why is it important that an official CLAM definition stops the virus before the 3rd party definition stops the same virus (if they both have the same criteria)? Surely a goal is a goal and it doesnt matter who kicked the ball. On 24/05/2016 11:54, Axb

[clamav-users] signature processing order

2016-05-24 Thread Axb
Good day, I've noticed that apparently third party (UNOFFICIAL) signatures get applied before the official ones. Depending on the signature types, we may never see any "official" sigs hitting, ever. Is there a scientific reason for this? (or am I missing something?) If no, could it be
