Hi I am changing Virus protection after McAfee's Dat file debacle up has wasted a day of my life. I am considering Eset and Kaspersky. I have 5 computers on the network. One of which is a server in the sense that is where my files are stored, my SQL database is served from and my Public Share Folder is served from and no user uses this computer on a daily basis. The operating system is Windows XP Pro SP3 on all 5 computers. If I go with Eset do I need both ESET® Smart Security: Business Edition and ESET NOD32® Antivirus v4: Business Edition. Thank you.
