I avoided AV software for most of my life. Though, when I worked as a student admin, I would always install AV for the majority of my users. Most users (especially older) simply could never learn not to download that cool new 'freeware' app or game or not double click a downloaded exe (the fact that hidden extensions are still the default on Windows OS is absurd). As a more savvy user, I did not desire the typical AV…
I find this a very dangerous way of thinking. You use the placebo (well, not even a placebo, just useless) and then you stop worrying that much about opening downloaded files, checking their hash if you trust the source, visiting dodgy websites...
An analogy taken to the extreme, would be to smoke and binge drinking without worries because you're taking homeopathic "solutions" (sic).
