Is there a mechansim for controlling the cpu load on windows 2003 standard edition 64-bit with kav5.0.77 64 bit installed?
There is no registry entry like this for 32bit ver.
HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\Components\2A\Fileserver\5.0.0.0

I havn't found registry entry for any setting

I had to shut down kav (luckilly, kavshell stop works ! ) because reply from fileserver was very slow (opening of an excel worksheet took dozen of seconds)

Does any KAV certified-64-bit version based on 6.x versions exists?

sure, read pls these informational materials:

http://www.kaspersky.com/anti-virus_window...rver_enterprise

For instance, for Enterprise Edition it's stated that the supported operating systems list includes:
Microsoft Windows Server 2003 x64 Standard Edition (Service Pack 2)
Microsoft Windows Server 2003 x64 Enterprise Edition (Service Pack 2)
Microsoft Windows Server 2003 x64 Datacenter Edition (Service Pack 2)
Microsoft Windows Server 2003 x64 Standard Edition R2 (Service Pack 2)
Microsoft Windows Server 2003 x64 Enterprise Edition R2 (Service Pack 2)
Microsoft Windows Server 2003 x64 Datacenter Edition R2 (Service Pack 2)

If you have a valid license for KAV for Windows File server, you should be able to update to this product for free.

Thank you,

I have downloaded this version: kav6.0.3.837_winserven.exe and it will be installed.
