RE: Why NOT to disable Real Time Antivirus on Servers

I would have to agree with George & Nick. Between the lessor of two
evils, to have or to have not, I would HAVE AV installed. I believe
taking a performance hit over, "who knows how long the network will be
down to sanitize the infection!", is the better choice. Just my 2 cents.

Classic case would be that a new Virus gets released and your 
enviroment doesnt have the DAT's yet , or the AV vendor hasnt 
released them. Someone gets an email, opens it and executes the 
attached exe file. Lets say this thing spreads on the LAN and 
infects everything, or targets servers and file shares. You then 
get the DAT file, update everything with AV and the problem starts 
to go away. 

Whooops, your servers dont have AV, they are infected.

      Greetings,
      
      An Engineer and I are having an argument about keeping Real Time 
Antivirus disabled on servers.
      
      His point is keeping Real Time Antivirus Enabled on servers such 
as the Exchange Server takes a huge performance hit on the server.
      
      My argument is that keeping real time antivirus software disabled 
defeats the purpose of PREVENTING a server from being infected in 
the first place. Once it is infected, it is all too late already. 
The antivirus software is enabled on the workstations.
      
      He argues that since all of the workstations have the antivirus 
enabled, then there is no way for the virus to get in.
      
      Mine argument that a virus can still get in through other means. I 
need examples and case studies to refer to.
      
      I would like to find different case studies or scenarios where the 
real time antivirus was disabled on the servers, enabled on the 
PCs, and the company still got infected. Also, would like to find 
solutions to enabling real time scan and stream lining it so it 
does not affect the Exchange Server as bad.
      
      Would someone point me in the right direction or post potential 
case studies.
      
      Please post or email me.
