Hey Steve,

I have read the support article on doscan.exe causing high cpu problems. I
curious to know if that would cause a problem in my environment where we
have no dos based applications. Is the doscan.exe installed by default? We
run basically 4 servers SBS 2003, Windows Server 2000, Windows Server Web
and Windows Server 2000 for GIS Applications. All of my clients are XP Pro
with full updates using SUS. Thanks for the heads up on the SAV CE 10.0 roll
out you did...im still trying to figure out the best route for our small
government office to take on this.

Hi Jason,

This last spring I was put in the position of deploying SAV CEv10.0 for 
my company - about 150 clients/servers.  Almost immediately it started 
causing problems.  I work for a video game developer for Playstation2 
games, and (sadly) a lot of the tools for PS2 are DOS-based (they're not 
Win32 apps).

First off there's an "issue" with 10.0 where doscan.exe causes high CPU 
usage - dragging the machine to a halt.  SAV does a "quick scan" (and I 
use the term loosely) on boot.  We've put in a regkey fix to remove the 
boot scan. 

They added "tamper protection" with a lot of our tools seem to trigger.  
We've had to disable that.

And generally has been responsbile for a LOT of performance problems.  
We're using high-end x86 dual-Xeon workstations, too - so it's not like 
we're under-powered.

Needless to say I'm currently doing a hefty performance analysis of 
other anti-virus solutions so I can find something "nicer" towards our 
environment.

HTH,
Steve
