We have just reasonly bought into NOD32 V4 AntiVirus Business Edition Installed in on 2 Windows XP Clients all seemed OK - When we installed it on our Windows 2003 Servers it ground them to a halt! - Not Good! After a short phonecall to the ESET Helpdesk they told me I had to add exclusions. He sent me a document a few links to check out; I have done this - If I add these will this cure it; Can anyone confirm? D:\System Files*.* (This contains off our AD Data) C:\Windows\System32*.* (For DNS, DHCP etc) C:\Program Files\Microsoft SQL Server (For SQL Server) C:\Windows\SoftwareDistribution*.* C:\Windows\Security*.* Is there any others that I should be aware off and that I should add....?
