Do you really have MS Exchange or Sharepoint and wanna have additional scan on this servers when this scan already done on client side? If answer equal to "no", than buy ABA AV instead ABA Pro.
Software Updater (free) has been killed to Patch Management (additional pay). There is no now any reasons to buy it ABA Pro if you don't have Exchange/Sharepoint. And I don't know anyone who wanna use it data-shredder constantly
