Well, I feel it would be helpful to see what that software has provided for you. Yes, it has made you aware of threats that it has blocked. Ok, but we also need to remember that the software has reported threats that the software has blocked - this type of report could be seen as the software maintaining the need for itself. The software makers gain profit from your use of their software.
There are some Mac veterans on these forums that have used Mac operating systems going back quite a bit - I remember some of them having experience as far back as OS 9 - and most of them are making claims that would suggest that AV software isn't needed on a Mac. These people do not profit from giving you their advice.. advice that has accumulated over many years.
Let's talk about handholding, as I feel it is detrimental to others. If we are constantly holding someone's hand (as in protecting them from harm), then they aren't able to learn as much as possible and fend for themselves. Remember the saying "Give a man a fish and you'll feed him for a day. Teach a man how to fish and you'll feed him for a lifetime"? I realize that you're aware of the dangers of relaying malware to others, but, and forgive me for saying so, that is called handholding - you aren't responsible for everyone else's computer, let others learn for themselves.
Rather than remove all AV software, turn it off for a while, follow the advice of the Mac veterans and see what happens. You know the healthy computer practices - they're listed in this thread - so follow those and.. see what happens. I'm not trying to tell you what to do, rather I'm giving you enough advice for you to be able to see for yourself - anti-handholding.
