Good write up, thx for reposting.
I use MSE and MWB on my personal pcs since I moved to win8. When I was running xp, vista and 7 I preferred Symantec's corporate versions. Work now uses webroot after we got sick of kaspersky grinding our laptops to a halt for simple updates.
Haven't done a family/friend computer fix in a while, but was still loading avast on those. I have heard of avira but haven't used it, I will now.
