Avira = (checked!) Definitely proven to be one of the light in footprint however contradict on some parts that can be problematic because of resource usage. Also their removal feature can be cause of problematic because of their process.
ESET = (checked!) Another accurate result here, 2 process and sometimes a scenario can spike high up resource usage but not always.
Kaspersky = well still remain likely questionable on some, since as you know they exert a lot of effort by providing patches on the build; however seems the components are not fully optimized for majority.
