I use AVG paid version licences for 10 computers for about $ 60 per yr but my'server' is a PC , so not sure how it would work on a real server .
at one time I was running both security essentials and AVG as the combo proved superior in eliminating viruses but since they both scan all files they often flag identity protection files , labcorp and AC files as viruses, so had to turn off identity protection and add AC as exceptions.
I have heard from others that Avira is a good free program to use
