We have many samples to process both automatically and manually. We prioritize those that actually appear in our userbase. If this is a 6 year old sample, there is 99.99999999 % chance that we already have it, so there is no need to send it over to be analyzed. It is just not viable to analyze old, low prevalent samples when there are many new samples that might be undetected as we speak now.
i was using zoo samples and 99% were blocked by deep screen
but now there not
deep screen will not block the malicious behavior now
it like the behavior signatures is excluded now from deep screen database
I do not understand why deep screen will not block virus/file infecting behavoir
What has changed? Or going on
