no av company adds within some few days all samples that are submitted to them, esp. not if they are not coming from users
Antivir, AVG and Ewido are doing this. I know because I have sent them samples and they have been added with 24 hours, in the case of Antivir and AVG, with a personal email in reply, not an automated message.
These were samples of new Feebs and Zlob variants.
These are obviously dangerous viruses- the avast! website lists Feebs as one of the latest threats, and a real threat- obtained from my email inbox or from web browsing.
These were not some exotic zoo viruses, so leaving them undetected would have left users of those products vulnerable to attack.
I still say not adding a sample within 24 hours is failing: it denies protection from that virus to users of the AV. If Kaspersky and others can do it in hours, then obviously that's the gold standard. 24 hours is in fact perhaps over generous- AV companies should do it quicker. Certainly making excuses for taking longer is not going to impress anybody who takes the time to submit a sample.
I've heard the excuse that avast! receives a huge number of emails, but I wonder: do Antivir and AVG receive fewer? Does avast! receive a disproportionate number of virus samples?
In fact the number of samples sent each day is a golden opportunity to improve detection. What more could an AV company ask than to be supplied with virus samples?
As to my submissions to avast!, sadly the response was a little less swift: my Feebs sample (a 'latest threat') is still undetected after 10 weeks.
