Added MBAM PRO and onto my list. They are not real-timer, however. MBAM, as the same as with the Free edition, I use it as on-demand scanner. MCShield, on the other hand, as its main purpose to protect from USB-source threat, I set it to start only when a USB device is plugged in. In this regard, I make use of Zentimo's after device plugging command to launch it and scan the plugged drive automatically.
I also removed resident AV from the list because after years of hosting them, I barely get anything important, let alone critical.
My Security setup that I've been using for the past two months:
Windows 8 Pro (patched upto date)
Avast Free antivirus v7
Online Armor Free Firewall v6
Firefox 19.0.1 with No-script, LastPass, AdblockPlus, WOT, BitDefender Traffic Light, Avast WebRep.
Sandboxie 3.76 Free version
MBAM and SAS for on demand scanning.
Try Comodo Firewall. in my opinion it's better than Online Armor.
