I got Premium for three dollars (one device/year).

I like Avast free.

I forgot to add, there is one exception that is from current testing here at MWT and that is that Eset and especially McAfee are very much relevant and top contenders... Eset has given some problems in my past use (can't remember what it was right now) but McAfee is smooth as silk.

I remember now, the problem with Eset was "failed to update, and failed to create file" something to that effect. It would not update on a clean install Image

I see Bitdefender free is 2d place in the votes behind No. 1 MS Defender -- does BD free have pop ups to buy their paid AV...

No, if you deselect to show in settings, but personally I prefer Avast free.
