Boo,

By coincidence, Consumer Reports did a review of the “free” anti-virus packages in the July 2015 issue.

Ratings as follows:

Top of the list went to: Avira (Free Antivirus 2015)

Next was AVD (AntiVirus Free 2015)

And then…..Avast (Free Antivirus 2015)

Last on the list was Microsoft Windows 8.1 with Defender
