After many months of asking which files constitute either V5 a/v (BE), or, Endpoint a/v V?, I rcvd many confusing answers; none of which really worked. Many here suggested I try Eset FS4WFS. OK! I have this code (v4.5.12005.0) running on my server 2 weeks. It works fine. I feel protected. Now, I'd like to create my Mirror and start focusing my PC clients to my server for their normal vdef updates. So,....... ...... what other code do I have to load on my server to enable this? There are just too many versions of ESET SW running around ATM. Confusing.
