[H] WHS 2008 & Virus Protection?

[Anthony Q. Martin]

I'm currently updating a PC with WHS 2008 (which says 2003 inside??).  
Should I install MS Security Essentials on this machine?  I'd rather not 
bonk this install as it seems to take quite a while to get it up 
(considering it didn't have any of the drivers needed for my mobo included).
