Good comments,

I know about the small sample sizes and the difficulty with proper testing conditions. I just find it interesting to see Avast (and the competition as well) in action with different files to see what it misses and what it catches.

Yes, you would need the big companies and the labs to do the proper representative testing. But they don’t have the time to put out the videos for the average Jane/Joe user who simply might find the videos interesting to watch. (As I do.)

I think it’s very interesting to see how the AV companies work night and day, every day to keep computer users safe.
