I currently using Avast Free on the systems here, tried Defender for a while with Malwarebytes free, but felt like maybe needed more, but if any issues develop out it comes lol, so far so good...

Contemplating Switching from Using Avast (over 10 years) to Defender on all househould systems, actually starting to like it now that using it more on Insider Preview PC, just gotta get mind secure...
