What free antivirus software works with MacOS Sierra?

[iMore Question]

My favorites are Sophos, Avast!, and Avira. But Avast! will not install under Sierra, and the other two are incompatible with Time Machine (hang it up).

Try Panda Security! Love it!

I had some silly PUPs that kept coming back a few months ago, BitDefender got rid of them in one scan.
