Having just installed systems on a new primary HD, and using Aol (which pretends not to use IE) AVG is enabled to scan email as well as all the other things.
I confess that yesterday in the initial istallation of one system the icon turned grey and insisted that email scanning was non functional!
I have done so much installing, configuring, and rebooting in this period that I can't remember how it returned to normal full cover.
Why not install it and check?
Do uninstall any other AV program first!
