BitDefender vs ESET NOD32 ?

I've used Avast Free in the past, but it ended up thinking my video drivers on my server were a virus and deleted them. I had other issues too.

I then bought Avira (my mistake) and it ends up finding programs on my computer over and over again, that I've already TOLD IT were okay. Even when I put them in the list to ignore, it still flags them every couple days.

So now I want to try ESET or Bit Defender. Which behaves better? I'm looking for a set-and-forget capability the most.
