Its probably worth noting that installing the same scanner in 3 places is not 3 layers 
of protection, its the same layer of protection 3 times. Not quite the same thing. 
 
If your vendor's scanner engine has a problem picking up a certain type of malware, or 
their dat files are slow in coming, you haven't done much for yourself by having their 
product installed in 3 different places. It doesn't matter how many metal detectors I 
walk through in an airport if the item i'm smuggling onto the plane is non-metallic.
 
And no software is perfect including antivirus software, so *all* scanners, even the 
ones we all regard as best of breed, will at some time have a problem spotting a new 
kind of malware stealth method, or the scanner's updates will be a bit slow one 
arriving one day.

        This company has three levels of protection, it didn't stop Sobig getting
        in, but it has stopped it getting back out again!

        Subject: 3 Layers of Virus protection.
        
        
        I was curious how many have 3 layers of protection for their email systems.
        My current assignment has me at a place where they are comfortable with
        desktop and a set of SMTP servers doing virus and spam. Desktop is Symantec
        and Trend on the SMTP servers. My gut feeling is to also protect the IS
        stores too. How many have 3 levels.
