Been using AVG for yonks and it has been pretty good. But after reading this thread and checking a few reviews decided to give MSE a go. Been on it a few days, it certainly seems less obtrusive than AVG.
I would recommend MSE.It's simple to install,it updates automatically via windows update and it doesn't hog CPU either,it just does it's stuff in the background.Hmmm,
I found AVG got a bit bloaty, then switched to Avast, but that's bloated a bit. MSE worth a try ?
