I use whatever Microsoft call their built in security this year, use ublock origin, and reinstall Windows about once a year. This seems to be the better alternative to having Norton/McCafe/<insert name of "security" program that uses more CPU than malware>.

ESET NOD32 is still going to be lighter and more performant than any alternative, including Windows Defender. The latter includes big delay for small file access, even just metadata!
