Well I decided to give Avast a try, and AVG too ,cause I'm bored. Actually I used Avast many years ago, was the first AV I used. Used Rollback RX Pro for this. My only comment is, wow, they sure try to upsell you a lot of useless crap, even did a custom install and they still try to get you. Now this isn't a comment on how effective it is, just on how they are the used car salesmen of AV's. AVG is just a clone of Avast, basically whats the point?? Now, my next experiment, Kaspersky free.
Edit: Tried Kaspersky, Bitdefender, and Avira as well, all free versions, quick 10 minute test drives, the only one I might consider ever using is Kaspersky. For now Defender with Configure Defender is good enough.
