That's very interesting
and good work on finding it because I didn't find much at all when I searched.
I saw a comment in that discussion that said, "There is really no benefit to running MSE and online Armor together. Uninstalling Online Armor should resolve the problem". Personally I am not at all sure about that. I don't know MSE at all so I can't attest to its ability to protect as a firewall.
I also noted that you may be able to set OnlineArmor to exclude a particular folder in MSE's program folders and that might prevent future warnings about this.
Again, good work and thanks for reporting back.
