".... and I am not seeing this issue in any other group... & ... if I remote in as an Admin it shows green...."
I am suspecting a policy problem(may be a corruption)... Because normally, if you gray down the users ability to change settings in policy , its not applied to the local admin dude... He can log in and change things... And also, I see the defs are uptodate... Just a basic step to check if SEPM contributes to this issue, move any one of the client to a group that does not have this problem... :) ... and observe...
Alternatively, you can copy the AVAS policy from a working-client-group and paste it here in this affected group...
Also, like rafeeq said, it could also be permission issues, but in that case I'm guessing you should have error relating SEP (Coh32, to be precise) in the event logs... Please check and get back.. :)
Cheers,
Visu.
