I just wondered if you remembered what the ticks in your old version were - I can't remember mine. I presume email protection is for Outlook Express or whatever it's called these days, but I don't use that, and Gmail and Hotmail have their own spam protection. But my AVG does list email protection and yours doesn't, I don't know why.
http://www.malwarebytes.org/ is worth having (also just use the free version). Other ABers may be able to offer more or better advice.
