Re: Av vendors

I have never heard of different AV engines sharing the same signature files. Each vendor develops their own virus 
definitions.
No vendor can always be the fastest in developing a signature to detect a new virus every single time. That is why you 
want to use multiple AV engines in the first place.
Look through the Securityfocus mailing list archive. I believe someone posted a link documenting various AV vendors' 
response time to the most famous virus outbreaks. You will note that different vendors had different response times for 
each outbreak.
