I found it interesting to note that Tom's Guide reports that AVG has been bought out by Avast, and the two AV engines were merged, making the latest version of Avast better than ever.
However, I just wonder if it is still possible to delete the little add on messages at the bottom of your emails that Avast used to add in. Or if there's a way to shut up any nags to buy the full program.

Tom's guide still likes Malware Bytes Free as a good add on program.
